Advantages and disadvantages of low pressure casting

The development of the casting field is obvious to all, and the casting methods have become diversified. Among the many casting methods, there is a low Pressure Casting, which is more important and has more advantages. Low pressure casting includes Investment Casting, Precision Casting, lost wax cating and Sand Casting. But each has its own characteristics. It is difficult for one method to be perfect, so low-pressure casting also has defects in some aspects. Shenzhen SCZY Technology Co., Ltd will introduce some advantages and disadvantages of low-pressure casting, which is also helpful to promote the improvement of products.

1. Advantages of low pressure casting

It can be seen through practice that the use of low-pressure casting to produce metal castings has a very high utilization rate of raw materials. Mainly because of its technology, there will be no runners and risers. In this way, the processing time will be greatly shortened, and the overall work efficiency will be greatly improved. Again, low-pressure casting is very suitable for some High air tightness, high-precision products, sand holes and pores of the product that cannot be improved by other casting processes, low-pressure casting is no problem.

It is also because of the production process that metal castings can form a directional solidification, which reduces the possibility of internal defects. Because of the above points, even if the operator's skills are not very good, it is still possible to cast products with excellent quality and performance.

2. Disadvantages of low pressure casting

In the low-pressure casting process, although the problems of the sprue and the riser are saved, the gate is still an obvious problem and is somewhat restricted. Moreover, low-pressure casting is not suitable for mass processing, because the productivity of this casting process is relatively poor, and its entire production cycle will be relatively long. In addition, the high control requirements for various data make low-pressure casting difficult in some aspects. Applications are restricted.
