Both vacuum plating and water plating are used in the surface treatment process of zinc alloy die casting parts in the die casting production process. Zinc alloy die-casting products are generally treated with appearance, because the processed die-casting products are more beautiful and wear-resistant. There are two electroplating processing methods for zinc alloy die casting parts, namely water electroplating and vacuum electroplating. The water electroplating process is suitable for zinc alloy die-casting products; it is mainly to put the electroplated products into the chemical plating solution for electroplating. Vacuum ion plating, also known as vacuum coating; suitable for zinc alloy die-casting products. Due to the cluttered process, high environmental and equipment requirements, the unit price is more expensive than water electroplating.
The biggest difference between water electroplating and vacuum electroplating is the price. The price of vacuum plating is higher than that of water plating. A brief overview of the pros and cons of both:
What is the electroplating surface treatment process for zinc alloy die-casting parts, after the above analysis, I believe you have a certain concept of vacuum electroplating and water electroplating! Of course, this is to decide according to our intention and structure. plan. Yuge Die Casting Factory is a professional manufacturer of zinc alloy die casting parts and aluminum alloy die casting parts. For more than ten years, the company has been dedicated to die casting. The process from mold design to surface treatment is very complex, and then to useful and progressive die casting parts. Good production quality and low production cost!
Product appearance cleaning, static removal -> spray primer -> vacuum coating -> spray paint -> baking finish -> packaging. Vacuum plating can be divided into ordinary vacuum plating, UV vacuum plating and vacuum plating; the process includes evaporation, sputtering, gun coloring, etc.
The water electroplating process is relatively simple and does not require vacuum ion electroplating from equipment to the environment, so it is widely used. However, the water plating layer is defective and can only be plated with ABS material and ABS + PC material (the effect of this material plating is not very satisfactory). The temperature resistance of ABS material is only 80 °C, which limits its application scale. However, vacuum plating can reach about 200 °C, enabling the plating of components used at high temperatures. For air nozzles and air nozzle rings, PC material is required, and these components need to withstand high temperatures of 130°C. In addition, high temperature resistant parts are generally required, and a layer of UV oil should be sprayed during vacuum plating to make the product look shiny, high temperature resistant, and combined to ensure adhesion.
