Surface treatment is a process for artificially forming a surface layer with different mechanical, physical and chemical properties on the surface of the substrate. The purpose of surface treatment is to have the corrosion resistance, wear resistance, decoration or other special functional requirements of the product. For metal castings, the more commonly used surface treatment methods are mechanical grinding, chemical treatment, surface heat treatment, and spraying the surface. The following will talk about details among all these different methods.

A woodworking sander is a tool or machine that uses an abrasive cloth or paper to make the surface of a wooden workpiece smooth.

Thermoforming or vacuum forming is a common method of processing plastic materials, and vacuum formed products are ubiquitous in daily life. The process involves heating a plastic sheet until soft and then placing it over a mold. A vacuum then draws the soft sheet into the mold. The sheet is allowed to cool and is then removed from the mold.

Polishing refers to the use of mechanical, chemical, or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It includes the modification of the surface of a workpiece using polishing tools and abrasive particles or other polishing media.

The spraying technology process has a wide range of applications, including industries such as steel, printing, aerospace, optoelectronics, corrosion protection, and petrochemicals.

In recent years, plastic electroplating has been widely used in decorative electroplating of plastic parts. ABS plastic is the most widely used kind of plastic electroplating.

It is inevitable that there will be some defects in the reprocessing process of metal-related mechanical equipment or parts. Therefore, the surface processing procedure of the last item is very important, and the function of surface beautification and protection is carried out, thereby improving the performance of metal parts and avoiding rust.

Generally, the steel blackening (black oxidation) treatment can effectively improve the corrosion resistance, but the protective effect is still quite limited. Oil immersion or subsequent rust prevention treatment is still required to really improve the corrosion resistance and lubricity of the blackened layer.

Anodizing is a process of surface treatment. The final process of metal manufacturing is surface finishing, anodizing precision machined metal parts, a reliable and relatively inexpensive method to improve wear resistance and coloring aluminum and other non-ferrous metals.
