The vacuum plating and water electroplating processes are all the surface treatments we use for zinc alloy die castings in the whole process of aluminum die casting production. Generous and wear-resistant. Zinc alloy die-casting electroplating processing technology is divided into two types, namely water electroplating process and vacuum plating. The processing technology of water electroplating process is suitable for zinc alloy die-casting products; it is mainly to put the products that need electroplating process into the organic chemical electroplating process solution. electroplating process.

The big difference between water electroplating and vacuum plating is the price

The price of vacuum plating is higher than that of over-water electroplating process, and the level of disorder of pure natural processing technology is also higher than that of over-water electroplating process. Briefly describe the advantages and disadvantages of the two:

• If the main vacuum plating is UV oil, the zinc alloy die-casting after the solution has poor adhesion and cannot pass the 100-grid test. From this point of view, water plating is better than vacuum plating! Therefore, vacuum plating is required. , Afterwards, it is necessary to carry out a special painting solution, so the cost increases.
• The color of the water electroplating process is simple, generally a small amount of color such as white chrome and black grid, but the vacuum plating requires a variety of colorful colors because of the requirement of middle and late production and processing.
• The general coating material of the water electroplating process adopts "hexavalent chromium", which is an environmentally friendly material.

What kind of electroplating process and surface treatment does zinc alloy die castings want to do? After analyzing the above aspects, I believe you already have a certain definition of vacuum plating and water electroplating process! Naturally, it depends on your intended use and structure. make decisions. Yuge Die Casting Factory is a professional manufacturer of zinc alloy die casting and aluminum alloy casting. Effectively develop the production quality of castings and reduce production costs!

Here is a brief and detailed introduction to its production process:

Commodity surface cleaning, antistatic --> spray paint --> bake finish --> vacuum plating --> spray paint --> bake paint --> packaging. Electroplating and spraying can be divided into general electroplating spraying, UV electroplating spraying, and electroplating spraying; processing techniques include evaporation, sputtering, gun color, etc.

The secondly difference between the two processing techniques:

The water electroplating process is generally used because of its simple processing technology, and the requirements from machinery and equipment to the natural environment are not as harsh as vacuum pump plasma spraying. However, the water electroplating process has a disadvantage, only ABS material and ABS+PC material are plated (the effect of this material plating is not very ideal).

The high temperature resistance of ABS material should be 80 ℃, which makes its application and operation scale controlled. However, electroplating and spraying can reach around 200℃, which can be solved by electroplating process for components used at high temperatures.

For example, the tuyere and tuyere ring is made of PC material, and these components are required to withstand a high temperature of 130 °C. In addition, it is generally stipulated that for heat-resistant components, a layer of UV oil must be sprayed for electroplating and spraying, so that the surface of the product has both gloss and heat resistance, and at the same time ensures adhesion.
