How the color of vacuum deposition is formed, and which gases are composed of different colors. In daily production, a wide variety of products come from different factories. Is the surface effect of the products coated by the same PVD coating machine the same? Are the colors all single and uniform? What are the effects of surface treatment on the color of PVD coating machines?

1、 Polishing treatment type
In the process of processing, transportation, storage and other processes, the surface of hardware workpieces often contains rust spots, yellow spots, polishing wax, oil stains and other pollutants. In order to improve the beauty, applicability and corrosion resistance of the product, it is necessary to do sanding, polishing or sand blasting and other pre-treatment on the product, and then conduct vacuum deposition plating. Moreover, surface treatment is also a key step to improve the adhesion of metal and vacuum deposition coating. Common polishing surfaces include laser light, mirror light, sand light, and vibration light.

2、 Will vacuum plating alter surface polishing?
For each different polishing effect, the unevenness of the product surface is different, and the reflection of light on the product surface is different. Therefore, the surface pre-treatment of different products is different, and the refracted luminosity and color also vary. Vacuum deposition is the process of transferring atoms or molecules from the source to the surface of the substrate, which is the material transfer of physical processes. PVD vacuum deposition generally does not change or affect the surface brightness of the product, so the gorgeous color or surface effect has a great reason with the product itself

3、 Frequently Asked Questions
Why is my product not as bright as other products after coating? For mirror light products with different finishes, even if produced in the same process, the effect after coating will still vary, so the brightness of the product is still closely related to the product itself.

4、 Why do products from the same furnace have different colors?
PVD coating machine coating is a physical combination of ions, not a fixed color added externally. Therefore, even products made with the same parameters may have inconsistent colors due to different materials and surface treatments.
