Surface Finishing Guide For Precision Machining

DALIAN, China - Nov. 8, 2021 - PRLog -- What Is Surface Treatment?

Surface treatment is a process of forming a surface layer on the surface of the basic material that is different from the body's mechanical, physical or chemical properties. The purpose of our surface treatment of products is to make the products meet certain requirements of corrosion resistance, wear resistance, decoration or other special functions. Surface finishing is the process of changing the surface of a manufactured metal part to a desired appearance or surface texture. There are different surface treatment methods and processes for different products.

Why Is Surface Treatment Important In Industrial Manufacturing?

With the development of the manufacturing industry, surface treatment technology plays an important role in the development of it. With the development of science and technology, the requirements of the manufacturing industry on metal surface treatment technology are getting higher and higher. Take the application in the automotive industry as an example. With the rapid development of the automobile industry, people have put forward higher and higher requirements for the ability of automobiles to withstand the external environment and the reliability, stability, corrosion resistance and appearance of the automobile for long-term operation. The surface treatment technology requirements they rely on also getting higher and higher.

Different Surface Treatment Processes

The main types of surface treatment commonly used in machining are: electrostatic spraying, baking varnish, galvanizing, chrome plating, nickel plating, titanium plating, gold plating, silver plating, aluminum anode, impregnation, oil spraying, sandblasting, DLC treatment, Teflon treatment , Black dyeing, cold plating, etc. We are here to introduce several common surface treatment types and their functions.

1. Electrostatic Spraying

Electrostatic spraying uses the action of a high-voltage electrostatic field to move the floating paint particles in the opposite direction of the electric field and adsorb the paint particles on the surface of the workpiece.

A thicker coating can be obtained by electrostatic spraying once, and the powder coating is solvent-free and pollution-free, which improves labor and hygiene conditions. The use of new techniques such as powder electrostatic spraying has higher efficiency, has a good performance for automatic assembly line production, and can be recycled.

2. Electroplating

This usually involves chemical and electrical processes to change the properties of the metal surface. Some examples are chrome plating, nickel plating, zinc plating, etc.
