A grinder is a widely used abrasive processing process in which a spinning wheel is covered with coarse grains. Cutting pieces of metallic or non-metallic substances from a workpiece to make the surface flat or smooth.
Powder coatings were developed in the 1950s as an alternative to traditional finishes such as liquid coatings. While the versatility and appeal of liquid coatings isn't likely to disappear anytime soon, powder coatings offer many advantages and are growing in popularity.
The metal surface is easy to rust and corrode in the natural state, which will cause excessive loss of metal products. At the same time, in order to meet the functional requirements of metal products such as brightness, wear resistance, and aesthetics, the coating on the metal surface plays a very important role. Surface treatment can improve product appearance, texture, function and other aspects of performance.
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.
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.
Metal fabricators looking to take on finishing should know about two of the most common finishing alternatives—liquid and powder coating—and the requirements involved for a company hoping to apply one or both.
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.
