        Rotherham出间pressure castingShenzhen zinc alloy pressure casting surface processing process is rich in colorful, and the actual effect of Shenzhen zinc alloy pressure casting casting on the Shenzhen zinc alloy pressure casting is very beautiful and generous. How to solve the actual effect of the surface layer of zinc alloy die -casting. Shenzhen zinc alloy pressure castings are generally used to high -end items, so the sales market has a large requirements for Shenzhen zinc alloy pressure castings. Therefore, how to improve the quality of Shenzhen zinc alloy pressure castings into a key daily task of Shenzhen zinc alloy die -casting plant. During the entire process of Shenzhen zinc alloy pressure casting manufacturing, the smooth production processing and mirror processing after the production processing and processing of production and processing is called the surface layer layer of grinding and polishing production processing. process. Grasp the effective polishing method, which can improve the quality and characteristics of Shenzhen zinc alloy pressure casting, thereby improving the quality of Shenzhen zinc alloy die casting products. Which kind of polishing and polishing method is used for Shenzhen zinc alloy die -casting plant 1. The key to grinding polishing Shenzhen Zinc alloy die -casting plant is to rely on drilling or plastic deformation of the surface layer of the raw material, and to remove the raised part of the steel surface layer to get smooth. The polishing and polishing method of the surface is tightly pressed on the surface of the steel parts in the research and processing of wear -resistant materials to do high -speed operation of fitness exercise. The roughness that can exceed RA0.008 \u0026 mu; M is the best in various polishing and polishing methods. Optical laser lens grinders often use this method. Rubing polishing is the key way for mold polishing. 2. Chemical polishing chemical polishing is part of the raw material in organic chemicals that make the external economy raised partly compared with partially selected and fused, and then obtain a smooth surface. This method can polish the complicated steel parts, and can polish many steel parts in addition to it, which is high efficiency. The roughness obtained by chemical polishing is generally RA10 \u0026 mu; m. 3. The basic concept of chemical polishing and chemical polishing is the same as chemical polishing, that is, the surface layer of the raw material is selected by selectively measuring the surface of the raw material, making the surface layer clean. Compared with chemical polishing, it can remove the harm reflected by the negative electrode, and the actual effect is good. 4. Ultrasound polishing and polishing ultrasound polishing is a production processing method of using a special tool horizontal surface as an ultrasonic vibration, according to the mixing of wear -resistant materials to polish the polishing crispy and hard raw materials. Put the steel parts into the wear -resistant material mixing and place the ultrasound together in the work. With the shock effect of the ultrasound, the wear -resistant material is cut and polished on the surface of the steel part. The macroeconomic efforts of ultrasound production and processing are not easy to cause steel parts, but the production and installation of workstors are more difficult. 5. Fluid mechanics Polishing and polishing fluid mechanics Polishment is the use of liquid liquid liquid and matte particles with matte particles with the surface layer of the steel parts that exceeds polishing. Fluid power grinding is a hydraulic driver. The key selection of the material is made of unique chemicals (high polymers lactating) with too strong working pressure and excessive. Essence 6. Magnetic lens polishing Magnetic mirror polishing is to use magnetic wear -resistant materials to produce wear -resistant materials under the efficacy of electromagnetic fields to produce and process steel parts cutting. This method is high -efficiency and cost -effective for production and processingHigh, production and processing standards are very easy to manipulate.Select suitable wear -resistant materials, the roughness of production and processing can exceed RA0.1 \u0026 mu; M.7. Spark discharge ultrasonic composite polishing and polishing Shenzhen zinc alloy die -casting plant in order to increase the roughness RA to 1.6 \u0026 mu; the polishing and pollution rate of the steel parts of about M, choose ultrasound and dedicated high -frequency narrow single pulse peak value volumeThe pulse power supply carries out compound polishing and polishing, which is used by ultrasonic vibration and the erosion of electrical sparks. In addition, it is also on the surface of the steel parts to quickly reduce its roughness.The abrasive gear is not smooth and polished and polished, and the actual effect is significant and very reasonable.Auto die casting parts神没还有在者说Wherepressure castingHighlanddiecastThe automotive industry is one of the key customers of the Chinese casting part industry chain. With the development trend of China's economic development and the improvement of the living standards of ordinary people, the parallel sales of Chinese automobile sales have increased. Essence With the increasingly higher and higher call of Chinese automobile new energy, the internal upgrading and upgrading of the automotive manufacturing industry is gradually implementing, and the aluminum alloy pressure casting is gradually replaced by ash -iron casting. The amount requires continues to rise. In addition, with the development planning of the aluminum pressure casting industry around the world, the need for aluminum alloy casting in various fields has continued to expand, and the development of the casting part industry chain is very broad. my country's economy maintains a trend of rapid development trend. Because the differences between resources and the natural environment are gradually deteriorating, according to the provisions of the construction of ecological civilization, the green economy and green manufacturing have become a key basic national conditions for the sustainable development concept of socio -economic development. Authoritative experts emphasize that the scope of aluminum die -casting, that is, contains a variety of working pressures such as low -pressure casting and squeezing and casting, causing shape processing processes, and its total output value is about 1.5 million tons. The manipulation of the ambient temperature of the die casting is very critical for the casting parts of production manufacturing. The temperature of the abnormal or uncomfortable mill can also cause unstable specifications of the casting. During the processing process, casting parts deformation, resulting in the disadvantages of heat work pressure, sticky mold, surface dentation, internal shrinkage and hot bubbles. When the difference between the mold temperature is very large, the independent variables in the production cycle, such as adding time, refrigeration time, and spraying time, will cause different levels of harm.和Redcar & Clevelanddiecast manufacturer体表Aluminum Alloy Die-castingWhere只见Aluminum Alloy Die-casting前就Auto die casting parts

What are the general defects and causes of die casting aluminum alloy castings? Answer: The strain has a band -shaped scar in the direction of the mold on the surface of the mold, there is a certain depth, and there are severe unilateral scars. The other is the damage of metal liquid and mold welding and adhesion. The surface of the casting lacks meat and meat. Reason: Damage to the surface of the mold cavity, the tilt of the mold pulling direction is too small, or tilted, there is an acute deflection, the injection temperature is too high, and it adheres to the alloy liquid. The effect of the molding agent is not good, and the iron content is lower than 0. 6% waiting for B bubbles: The surface of the casting has a grain of rice bump, and a hole is formed under the skin. The reason is that the liquid of the alloy is too low to meet the pressure of the pressure chamber. The melting temperature is too high, the mold temperature is too high, the metal solidification time is insufficient, and the strength is insufficient. C: The cold -spacing wall on the surface, the die -casting parts are clear, there are two irregularities, uneven line patterns (penetrating and penetrating? The shape is thin and fine. Sometimes the edges become smooth and may follow the edges, and may be as the edges become smooth, and may be as smooth as the edges. The role of external forces develops. Two metal currents are connected to each other, but they are not completely reconciled. They do not insert between them. There are two metal bonding weak milk. It is not suitable for choosing a low -temperature alloy. Due to poor liquidity, is the lane location incorrect? Or the traffic is very long. The charging speed is indeed very low, and the pressure radiation is lower than the pressure. D: color change, spots: the surface of the casting has different metal color ratio substrates. Reasons: Improper molding agent, excessive dosage of the molding agent, excessive work, the graphite in the lubricant containing graphite falls on the surface of the casting.        之先Which majorpressure castingIs there a solution这好diecasting manufacturerHow much is the general charge陀的We sincerely invite you to inquiremethod心激Aluminum Alloy Die-casting4. Enthusiastic processing LOE should pay attention to what enthusiastic processing is to change the die -casting material that changes the combination of gold, through enthusiasm and cooling, the intensity, hardness, viscosity, high temperature under size stability, enthusiasm, enthusiasm under size stability, enthusiasm, enthusiasm Fatigue anti -fatigue, processability, such as cutting work, it is my phone acquisition. The description of the enthusiastic processing of die -casting: The same material requires the quality and performance of the same material after the same hardness processing, and the quality and performance are completely different. The H13-based thermal treatment technology and the gold after thermal treatment are based on the regulations of the North American Die Casting Association (NADCA 207-2003). The mold steel sales company recommends the heat treatment of the mold to avoid the occurrence of quality disputes caused by different materials and thermal treatment manufacturers. The quality of high -pressure liquid nitrogen -cooled vacuum furnace quenching products is H13 steel dice. The surface of the mold, oxidation, and deformation of the mold can prevent [2,3]. The quenching temperature rises to 1020 \u0026 deg; C ~ 1050 \u0026 deg; The mold, heat treatment is not enough to dissolve carbohydrate compounds, and the type of cracks stay between the crystal boundary. However, Gangliden Point AC1 and AC3 want to heat up to prevent rough orsera [4,5]. Different acceptable can be baked three times under hardening temperature, and then keep two to three times. In addition, when nitrifying treatment, it can be the process of MRR once the fire returns. The cutting stress stress in the mold processing, the stress of the retention of the residue, the thermal fatigue stress generated by the die casting, the light MRR generated by igniting, or it can be eliminated. Moom is a stress fire treatment of cyclical solution: the first ignition treatment before quenching (the fire temperature is 700 \u0026 deg; c ~ 750 \u0026 deg; Once, the exit process. The stress temperature of H13 steel is lower than the stress temperature at the last quenching of 20 \u0026 deg; C ~ 40 \u0026 deg; c, the insulation time is 1 to 1.5 hours. The hardness of the mold is reasonable, the American AISI H13 ESR material is used in bird type. If the hardness is too low, the bonding type and early cracks are the current level. If it is too high, the risk of cracking may be increased. The alloy is 47 ~ 52HRC, which is used for mold pressure connection; 46 ~ 48HRC is inhibited by the magnesium alloy into small aluminum and magnesium alloy molds; large aluminum, magnesium alloy molds, the thickness and form of the stump and the hardness will be reduced to 44 ~ 46HRC. Hitachi DAC55, ZHD435, 1 win 100DIEVAR steel performance is excellent when the hardness and heat resistance are high, and the intensity of 2 ~ 4HRC may be increased by 2 ~ 4HRC when applying. The type of mold type is easy to mold, suitable for various molds, nitrogen, carbon nitrogen sedimentation, Japanese KANUC, low -temperature plasma pottery, evaporation (PVD physical gas deposition, CVD chemical gas deposition), nitride, gas deposition, laser [6] are selected for strong surface treatment, such as MRR bonding or erosion.Now, we often use Japan Kanuc.In addition, when nitrogen is needed, the total depth of the surface nitride layer is less than 0.2 ~ 0.3 mm, and the thickness of the casting wall is suppressed from 0.04 ~ 0.08 ~ 0.12 mm to thin, and the white bright layer of non -complex is quickly cracking.Easy -to -adhesive parts can be treated by surface treatment, such as nitrogen with 1 to 20,000 molds per die -casting 1 to 20,000 molds.After the mold pressure casting 80,000 ~ 100,000 molds, the hardness of the mRR has a force or similar possible occurrence, or it can also be treated with nitrogen.In addition, the mold surface is released by light after exit and before the wind removal.Which is near虫两diecasting3. Factors affecting shadow polishing quality of the shadow. Because the polishing of the machine is mainly done manually, the appointment of polishing technology is also the main reason for the current level of the raid quality. In addition, it continuously involves mold materials and surface environment before polishing, and enthusiastic processing technology appointments. It is better that because steel materials are prerequisite for obtaining abrasive quality, if there are differences in hardness and surface characteristics, it is easy to grind. Various switches and air holes in the steel are not conducive to gloss. 3.1 Hardness is the appointment of increasing hardness affecting polishing technology and increasing the effect of polishing, but the roughness of polishing is MRR. Due to high hardness, the polishing time required to be lower. It also has higher hardness and less polishing opportunities. 3.2 The appointment of the appointment of the shadow effect of steel materials The surface of the appointment of the project parts is a broken past cutting machine processing, which is kept on the surface of the cutting machine, internal stress, or is broken by other elements. The failure of the cutting parameter affects the shadow to the polishing effect. The surface of the electric spark processing, due to the polished general machine processing surface and enthusiastic processing, is Comare polar \u0026 quot; if there is no proper selection of the electric fireworks, the depth of the thermal influencing layer will rise to 0.4 mm. Because the thin residue of hardening is higher than the substrate hardness, it must be removed. Therefore, it eliminates residues on the surface of the scratches on the bottom of the sea and established an average coarse metal surface, providing a good foundation for polishing.

Mold manufacturing is generally carried out at the temperature of 150 to 200 degrees Celsius, with constant pressure and temperature effects. Therefore, the performance and quality of the steel materials of the mold are important. What are the requirements for plastic steel? 1. Outstanding processing: Except for EMD processing, fixed processing and assembly and maintenance, most plastic molds need to be carried out. In order to extend the service life of the tool, improve the cutting performance, and reduce the surface roughness, the hardness of the steel must be suitable for the mold. 2. Good thermal stability: Due to the complexity of the injection molding parts, it is difficult to process after quenching, so it is necessary to choose an injection molding part with the best thermal stability to ensure the accuracy and surface roughness requirements of the mold size. 3. Good polishing performance: High -quality injection molding products, which require small surface roughness value of the cavity. The selected steel is a material with less impurities, uniform tissue, and no directional fibers. It requires no marijuana or orange defects during polishing. 4. enough surface hardness and abrasion resistance: The hardness of plastic molds is usually 50-60 HRC or lower. The heating molds require sufficient surface hardness to ensure that the mold has sufficient rigidity. Because the mold must withstand pressure stress and friction, large filling and plastic flow during the operation, it is necessary to maintain the accuracy and size accuracy of the mold shape to ensure that the mold has sufficient service life. Because the abrasion resistance of the mold depends on the chemical composition and thermal treatment of the steel, enhanced the hardness of the mold is conducive to improving the wear resistance of the mold. When selecting materials, for example, when the surface is relative to move, consider preventing adherence to wear and tissue structure so that the same material can be selected. In special cases, it may be plated or nitride on one one. There are different surface structures on both sides.nearbyThe injection molding mold is classified as a processing process method completed in the forging liquid mold and dedicated type die -casting mold. For aluminum die casting, the three factors of aluminum pressure casting material, aluminum pressure casting machine and abrasive gear are indispensable. In the process of application production, it can develop production output power, well -known brand quality and high economic income, and allow injection molding molds to obtain the application of life limit. The application and maintenance of injection molding molds is very critical. Proper application and maintenance methods of injection molding molds: 1. Reduce the rapid cold and hot heat of the grinding gear as much as possible, and continue to produce as much as possible. In the case of cold molds, it is strictly forbidden to shoot quickly. In the process of aluminum pressure casting, the injection molding mold has always been in the reciprocating fatigue situation of thermal expansion and contraction. Most of the temperature of the grinding mold concave mold has always been changed at 160 degrees-350 degrees. Then, the abrasives were fatigue and destruction. In the case of cold molds, the temperature of the mill has begun to increase from the ultra -low temperature, the temperature difference increases, and the decrease in the abrasive gear increased. The tiredness of the abrasive manifestation is relatively increased, which will accelerate the abrasion of the abrasive and reduce the life limit of the abrasive. Therefore, when the production of aluminum pressure casting, it is necessary to continue to produce as much as possible, minimize the rapid heat and heat of the grinding gear as much as possible, and then broaden the abrasive life limit. In addition, under the condition of cold molds, the mill does not reach the temperature when all normal production, and the gaps in each place are relatively large. Under such conditions, it is strictly forbidden to open the speed and increase. Otherwise, the gap in each gap, which contains the position of the rail slider, the small chain holes, etc., and then simply string into the aluminum skin, and then destroy the abrasive manifestation to harm the abrasive life limit. 2. Reduce the voltage rate as much as possible, reduce the pressure as much as possible, and reduce the impact of the grinding gear. During the production of aluminum pressure casting, the height of the firing rate is not only endangered the charging rate of aluminum die casting, the internal adhesive oral rate of the firing internal inlet, a high voltage rate, and the maximum impact value will increase. Therefore, the firing rate is high, the internal tape is faster, the erosion of the mill will increase, the impact maximum value increases, the impact force of the abrasive adoption will increase, and the abrasive life limit will be greatly reduced. Therefore, when we regulate the casting process, we will reduce the voltage of the voltage as much as possible under the condition of ensuring the quality of the product, the development limit of the development of abrasiveware, and the economic income of the development of aluminum die -casting companies is very critical. At this stage, the excellent aluminum pressure casting machine weapon equipment has the equipment and equipment of the ejaculation and brake pedal, which has the highest impact value to reduce the impact value, reduce the impact of abrasive adoption, and develop the abrasive life limit. The voltage ratio in the casting process is also a key main parameter. The voltage ratio is generally 400-900kg/cubic centimeter according to the quality regulations and its characteristics of the casting component. Over 900kg/cubic centimeters, the general effect of internal quality of the casting is not great. The high voltage ratio is too high, not only to increase the rising force of the abrasive accepted, but even the locking force of the rising power over CNC lathe, producing aluminum. Together, if the abrasive has a large increase in power, it will also destroy the abrasive or reduce the lifting of the abrasive life. Therefore, in the production of aluminum pressure casting, in addition to the high attention of the firing rate, we should pay more attention to the voltage ratio of pressure. Because the voltage ratio is not a simple research on the firing rate, it is usually careless. In fact, pressure -compacted compression is a key parameter in the casting process, not only harmThe quality of the casting components is also very harmful to the abrasive life limit. This should be very important to attach great importance to aluminum die -casting companies. 3. The abrasive application should be combed immediately to avoid squeezing the abrasive. In the application of the mill, the abrasive gear and aluminum skin will usually appear because of a variety of causes. At this time, it must be sorted out immediately. Otherwise, it will squeeze the grinding gear. It is a very guide rail slider position. If the ropeway enters the aluminum skin, etc., because the aluminum pressure casting machine lock the mold is very large, the guide rail slider will collapse and break. Therefore, when encountering such problems, the grinders must be sorted out immediately, and the abrasives are repaired immediately for the reason. Otherwise, it will be more severely harmful to the abrasive set of the abrasive life limit when the mill is destroyed. 4. Reduce the watering temperature of the lithium bromide solution as much as possible, and develop the application life limit. The pouring temperature of the lithium bromide solution during the production of aluminum pressure casting not only endangers the quality of casting components, but also harms the application life limit of injection molding molds. When aluminum die-casting, the pouring temperature of the lithium bromide solution is 630 degrees -720 degrees. For different parts, we should choose as low as possible when choosing the pouring temperature. Application life limit. Because the higher the temperature of the lithium bromide solution, the greater the grinding of the mill, the greater the operating scale of the temperature gradient of the mill, the greater the hot increase and contraction. Therefore, properly reducing the watering temperature of lithium bromide solution, which is beneficial to widen the life limit of injection molding molds. 5. Improve the maintenance of the abrasive, perform maintenance regularly, and perform quenching stress solutions on the time of timely execution of the abrasive concave mold. Injection molds have always been produced under pressure, speed, and high temperature, and the application standards are extremely extreme. During the entire application process, the grinding gear will cause damage or problem risk. Therefore, to improve the maintenance of the abrasiveware, perform maintenance of the abrasives regularly, replace the destruction position, replace the parts, and combine the ropeway, small chain holes, etc., which is very important. Sexuality can also broaden the application life limit of abrasives. Together, because the injection molding mold continues to be damaged in the application and continues to heat up, it will produce new thermal stress. If it is not removed immediately, the abrasive set layer is simply cracking or cracking. Therefore, the regular execution of the ground stress quenching of the grinding gear molding, clearing the stress, is also the key technique of broadening the abrasive life limit. Under general conditions, after the application of funds is applied, the initial quenching should be carried out after 3000-5000 models. In the future, according to the application status, each of the 10,000 abrasives is produced up and down, and the ground stress quenching needs to be carried out on the grinding equipment, which can greatly broaden the application life limit of the grinding gear.Selection of processing methods in high -speed processing programming. With the introduction of high -speed processing centers, mold companies have begun to achieve high -precision and high -efficiency mold manufacturing through application high -speed processing solutions. High -speed milling programming involves the surface and use of the CNC servo system and processing materials. In CNC programming using the CAM system, you can not only choose the tool, cutting dosage and corresponding processing parameters, but also set the corresponding processing parameters according to the situation. Selecting processing methods are the key to high -speed processing CNC programming. By selecting the appropriate processing method, the following points need to be considered to achieve high -speed processing. (1) The high -speed processing center has a positive visual and preview function. When the tool needs sharp curves, the processing center slows down in advance, and the movement speed is improved after the rotation is completed. The function of the machine tool is mainly to damage the spindle and machine tool of the inertia groove to avoid big inertia shocks. Although some high -speed machining centers can withstand inertial impacts, without this function, this situation is not conducive to the main axis of the lathe, which affects the part of life, such as the main axis. When using CAM for digital programming, make sure the exercise of the tool is as smooth as possible. (2) Due to the movement speed of the tool in the high -speed processing process, because the tool is usually very small, in order to keep the tool fixed in the processing process, the knife is needed to avoid overloading. Whether the load of the tool is uniform, which directly affects the life of the tool, and it also directly affects the main axis of the machine tool, because sometimes it causes cracking when the tool load is too large. (3) A safer and more effective processing method and fast safety inspection and analysis. Example: Check the interference of the bracket and head to ensure the safety of the path trajectory.Auto die casting parts

2022Latested:Aluminum pressure casting is a product. It is made of aluminum into a liquid, and the aluminum is made of aluminum. The aluminum and high -speed injection of the die -casting mold cavity. After cooling the aluminum water, it can be formed by opening the mold. However, aluminum die casting uses aluminum ingots instead of waste aluminum. Waste aluminum contains a large amount of impurities, affecting die casting work. What are the functions and characteristics of aluminum casting parts in life: 1. Aluminum pressure casting has excellent durability, which is the performance of many castings. 2. Aluminum stability, strong oxidation, aluminum die is not rust, and corrosion resistance. Therefore, aluminum die -casting is adopted by many decorations and can remain non -fading. 3. Aluminum die casting is safe. Aluminum products have excellent seismic resistance. Many experiments have shown that the resistance of wind pressure and weathering is amazing. Therefore, using aluminum castings, we become safer. In addition, the weight of aluminum die -casting is relatively light, which can reduce people's burden and reduce risks. 4. Due to the good toughness of aluminum, it can determine its plasticity, design various shapes, and the elongation is particularly good. Therefore, aluminum castings can be used for recycling, saving materials, and expanding the scope of application. This characteristic of aluminum also determines its creativity. It is very good and can be modified freely. 5. The aluminum is relatively light, so even if it is installed, maintenance can be used without pressure.度达diecast manufacturerTrick变成diecastingThe melting of zinc alloy materials is a key step in the whole process of zinc alloy die casting in Dongguan. It changes from solids to liquid based on the melting aluminum alloy. This is a complicated whole process of organic chemistry and physics. Slag, mud dregs are mainly chemicals of iron, zinc, and aluminum metal materials, but with zinc alloy materials with more than 90 % percent, the response time generated by zinc residue will be increased with the rise of temperature and increase In order to reduce the cause of low zinc slag, the following content should be used: 1. Strictly control the temperature of the smelting. Due to the higher the temperature, the more zinc slag will be. 2. Try to avoid regularly stirring the aluminum alloy liquid in zinc cookers. Due to the stirring of all methods, a large amount of cumulative liquid and oxygen molecules in the air are fused, and a large amount of zinc residue is generated. 3. When carrying out the slag, it is necessary to apply a porous structure of the plate -shaped scum, and slowly scrape it under the mud residue to avoid mixing the aluminum alloy liquid as much as possible. The slag rake slowly beaten by the zinc pot to return the metal material flow liquid to the zinc pot. 4, cut slag does not have to be overly frequent. When the melted aluminum alloy is exposed to the gas, it is all produced by air oxidation and mud residue. If unremarkable slag, it will save a thin layer of mud dregs on the furnace surface, which is beneficial to the liquid in the pot. Oxidation, this is also a point in Shanghai zinc alloy die casting. 5. Metal materials such as chromium, copper, nickel and other metal materials with electroplating process waste are not dissolved in zinc. When they stay in zinc alloy materials, they will be stored in hard fine particles, which will make it difficult to polish and mechanical processing. Therefore, it is necessary to prevent it from putting it in the zinc cooker of the casting part immediately, but it is redefined and refined and then aluminum die casting. How can Dongguan zinc alloy die casting reduce zinc residue? According to the above show, everyone has some understanding. When carrying out the zinc alloy die casting in Dongguan, we must pay attention to the mixing aluminum alloy liquid and slag that does not have to be excessive. Oxidation, so, brings a lot of zinc alloy materials.者之diecast manufacturerThe casting components of Shenzhen die -casting plant are high -efficiency production and processing methods for forming. It can produce components that are complicated and processed. The use of car bathrooms and sanitary ware in small cars and home. However, zinc alloy materials do not resist air erosion. It is necessary to roll on its surface, chromium safety protection and decorative art paint. The conventional characteristics of steel items and unique production and processing methods are very harmful to the electroplating process. 1) The raw materials for aluminum alloy casting are zinc -aluminum alloy profiles, all of which are cheerful two -sex metal materials. Among the two metal materials, aluminum is more difficult to solve in front and plating process. Therefore, it is necessary to manipulate aluminum water content. Generally, the raw material of zinc alloy casting casting of rust electroplating process. If the aluminum water content is too high, the electroplating process will not be able to carry out normally. 2) The parts design scheme should be effective. The appearance of the casting parts should be taken into account the covering ability of the electroplating process. Try to avoid not buried the holes so that the hand washing is not easy to bring the aqueous solution. Reduce the position of the diagonal angle, so that the high -pressure lines are well -proportioned during the electroplating process. 3) The design of the casting process and die -casting mold is effective, so that the casting parts do not cause shortcomings such as shrinkage, needle eye and loosening. The disadvantages will immediately harm the binding of the coating. 4) During the whole process of aluminum pressure, try to avoid shrinkage. For example, aluminum shrinking in some places, when the oil is off, the aluminum is first melted. It will cause stomach and needle eye to be cleaned on the surface of the casting part, resulting in a poor binding. 5) During the whole process of grinding and polishing, you should pay attention to the sense of measurement. The high -density layer of 0.05 to 0.1mm produced during the whole process of casting parts is very critical to the electroplating process. If this layer is thrown away, the exposed porous material will be exposed, and then this layer will not be able to obtain a good electroplating process layer. 6) The copper, one nickel and one -chromium plating process composed of multi -plated species, is relatively compared to routine, can only be mechanical and equipment maintenance effects. Therefore, be sure to ensure that the coating has no holes. Otherwise, the etching substance of zinc alloy material will make the coating bubble. In terms of relative nature, the coating should be two thicker, and zinc alloy casting can be used. 7) The sediment in the process of casting parts in the whole process of aluminum pressure casting and mechanical processing should be cleaned up as much as possible after production and processing. Because sediment is a cheerful metal material, in all the processes of the electroplating process, it is reflected with the aqueous solution, and the destruction of the plating solution will cause the quality of the electroplating process.不知Metal die casting Auto die casting partsWhich is more professional
