Surface treatment process for screws


The colors of the screws are very diverse, and a variety of colors can be produced according to the needs of the product. The colors of the screws can be diversified. After the screws are produced, they are subjected to surface treatments such as electroplating again, and the metal layers of other colors are covered on the surface of the screws. This is the variety of colors we see.
The surface treatment involves another problem. Different materials have different surface treatments, and the colors that can be produced will also be limited.
For example, carbon steel material, it can be electroplated into a variety of colors, gold, silver, black, etc., and the plating effect is very good, can stainless steel screws? Of course, stainless steel screws can also be plated in various colors, but stainless steel screw manufacturers do not recommend it. Generally, stainless steel screws are mostly treated with natural colors, that is, after cleaning oil stains. This is because the properties of stainless steel materials are different. When other colors are plated, When covering the surface of stainless steel screws, they are not as perfect as carbon steel screws. After plating of stainless steel screws, the plating layer is easy to fall off, and during the plating, collisions between screws and screws are prone to cause defects on the screw surface.
