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 oxidative 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.
2. Stomata and shrinkage
The porosity problem is the most common in the process of low pressure casting. It is generally caused by the poor exhaust of the casting tool, the poor spraying of the mold coating system, and the improper setting of the cooling ring, which can also lead to the generation of porosity and shrinkage.
3. 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 our country’s processing technology. With the development of technology, its drawbacks are increasingly emerging. Only by analyzing the root cause of the problem can we solve the problem better.
