Vacuum coating is widely used in various industries, including machinery, electronics, hardware, aerospace, medical, chemical and other fields, so what is the difference between before and after PVD coating, and where is it reflected? So many industries are using it and there must be a reason for its existence.
Briefly talk about the difference before and after PVD coating:
1.After the product is coated, a protective film will be formed on the surface of the product, which can effectively resist corrosion, be more wear-resistant, and improve product quality.
2.The coating can change the appearance of the product. It can be electroplated with different colors and appearances according to different product customer groups to meet consumer needs, such as hardware vacuum coating 18k gold.
3.The thicker the electroplating film, the longer the color retention time.
4.Due to the extension of quality and service life after electroplating, it can bring added value to the product, which is conducive to improving the economic benefits of the product.
For PVD vacuum coating, different products should choose the appropriate electroplating process, magnetron sputtering plating (mainly metal products), evaporation plating (mainly plastic products), optical ion plating (mainly glass products), and there are also a variety of colors to choose from. .
The following is a brief introduction to the before and after comparison of the surface of PVD-coated mold parts:
By comparison, we can see the obvious advantages of PVD coating from the picture: the film layer has wear resistance, corrosion resistance, high hardness, dry lubricity, beautiful, gorgeous, and environmental protection.
