Alloy Steel Precision Casting

Low pressure casting is widely used in metal processing technology and plays a huge role in my country's modern industry. With the wide application of low pressure casting in my country, the drawbacks it brings are also exposed.

   1. Oxidation of slag inclusions

The reason for the occurrence of oxidized slag inclusion is generally because the charge is not clean, or the charge is used too many times during the use process. Poor design, improper settings when filling. ,

   Second, pores, shrinkage holes

  The problem of porosity is common in the process of low pressure casting. It is generally caused by poor exhaust of the casting tool, poor spraying of the mold coating system, and improper setting of the cooling ring, which can also lead to porosity and shrinkage.

  Three, cracks

In the process of low pressure casting, cracks are very common. The design of the mold is unreasonable. The sharp corners and the difference in the thickness of the wall will lead to cracks. In order to eradicate the cracks, it is inevitable to improve the structural design of the mold. Only when the design of the mold is reasonable can it help to solve the problem.

  Low pressure casting technology is widely used in the processing technology of our country. With the development of technology, the drawbacks are becoming more and more obvious. Only by analyzing the root cause of the problem can we solve the problem better.
