Tangshan Xinye technology introduced the coated sand process

Coated sand process, an advanced technology in the casting industry, has won the favor of many casting enterprises with its unique process flow and excellent casting quality. Xinye Technology will give you a detailed introduction to the coated sand process, so that you can appreciate its charm.

Coated sand process, as the name suggests, is to cover the surface of the sand with a layer of special material film. This layer of film is like putting on a "protective coat" to the sand mold, which plays a crucial role in the casting process. So, what is the magic of the coated sand process?

First of all, the coated sand process can improve the finish of the casting surface. In the traditional casting process, due to the direct contact between the sand mold and the casting, it often leaves rough sand marks, which affects the appearance quality of the casting. By coating the surface of the sand mold, the sand mold is isolated from the casting, which makes the surface of the casting more smooth and greatly improves the appearance quality of the casting.

Secondly, the film sand process can improve the dimensional accuracy of the casting. In the casting process, due to the shrinkage and deformation of the sand mold, it often leads to the deviation of the casting size. The coated material used in the coated sand process has good dimensional stability, which can effectively reduce the dimensional deviation and improve the dimensional accuracy of the casting.

Thirdly, the coated sand process can improve the internal quality of the casting. In the casting process, due to the poor permeability of the sand mold, it will lead to bubbles, shrinkage holes and other defects in the casting. The film coated material used in the film coated sand process has good permeability, can effectively discharge the gas in the mold, reduce the defects inside the casting, and improve the internal quality of the casting.

In addition, the coated sand process also has good sand resistance, which can reduce the sand phenomenon on the surface of the casting and improve the surface quality of the casting. At the same time, the coated sand process can also improve the strength of the sand mold, reduce the damage in the process of handling and assembly, and improve the efficiency of casting production.

In short, as an advanced casting process, the coated sand process has many advantages and is widely used in the casting industry. With the continuous development and improvement of the coated sand process, it is believed that it will play a more important role in the future casting production. Let's look forward to the coated sand process to bring more surprises and changes to the foundry industry.
