Low pressure casting is widely used in metal processing technology, and plays a great role in China's modern industry. With the widespread use of low pressure casting in China, its disadvantages are also exposed.
Low pressure casting is widely used in metal processing technology, and plays a great role in China's modern industry. With the widespread use of low pressure casting in China, its disadvantages are also exposed.
1. oxidation slag
The reason for the occurrence of oxidation slag inclusion is generally because the burden is not clean, or in the process of use, the use of the burden is too many times, there is another reason can also lead to oxidation slag inclusion in the process of low pressure casting, that is, the poor design of the casting system, the improper setting of the filling.
2. stomata and shrinkage cavity
The problem of air holes is common in the process of low pressure casting. It is generally caused by poor exhaust of casting tools, poor spraying of mold coating system, improper setting of cooling ring, which can also lead to the generation of air holes and shrinkage holes.
3. crack
In the process of low-pressure casting, cracks are very common, the design of the mold is unreasonable, sharp corners, the difference in the thickness of the wall will lead to the phenomenon of cracks, in order to eradicate the phenomenon of cracks, improve the structure design of the mold is the inevitable choice, only the design of the mold is reasonable, the solution to the problem is helpful.
Low pressure casting technology is widely used in the processing technology of our country. With the development of technology, the disadvantages are becoming more and more obvious. Only by analyzing the root causes of the problems can we solve the problems well.
