Surface treatment is a process of changing the surface of metal materials:

Dalian metal surface treatment is an ancient technology that has been mastered by humans since the existence of humans on Earth. The life of primitive humans was difficult, living in groups. In order to survive, they made stone tools and used grinding technology to make the stone tools have sharp edges, producing a "sharp cutting" effect. In the Neolithic era, the stone tools used by primitive people were polished throughout, with a delicate and smooth surface.

What products are PC plastic particles used for

① Hand polishing tools. Manual polishing is mainly carried out by wrapping wooden blocks (rubber blocks) with sandpaper or wooden blocks (rubber blocks) with water sandpaper. Wooden block sanding cloth is mainly used for dry grinding of putty layer, while water sandpaper wrapped rubber block is mainly suitable for water grinding of fine putty and intermediate coating paint film. When using manual polishing tools, they are usually paired with tools such as a scraper, brush, cotton yarn, etc. If dry grinding putty, you can first use a scraper to remove the burrs on the surface of the putty layer, smooth and rough scratches, and then polish it.

Dalian surface heat treatment can significantly improve the fatigue strength of workpieces:

Dalian surface heat treatment can significantly improve the fatigue strength of workpieces. For example, the automotive half shaft made of 40MnB steel was originally quenched and tempered as a whole, but was changed to quenched and tempered+surface heat treatment, which increased its lifespan by nearly 20 times. In addition, surface heat treatment reduced the sensitivity of the parts to notches. The size of the outer panel mold is generally larger,

The steps of Dalian metal spraying usually include the following processes

Dalian metal spraying is a common method of metal surface treatment, also known as metal coating or metal coating. It forms a protective or decorative layer by spraying paint onto the metal surface, in order to improve the corrosion resistance, wear resistance, and appearance of the metal.

The steps of Dalian metal spraying usually include the following processes:

What are the common surface treatment methods for Dalian metals?

Dalian metal surface treatment is a common process used to improve the performance and appearance of metal surfaces. It can provide the anti-corrosion, rust prevention, wear resistance, corrosion resistance and other characteristics of metal materials, while also beautifying the metal surface, improving its appearance and texture.
