Process type of precision casting of stainless steel plate

Stainless steel precision castingAlso known as investment casting. This process avoids or basically does not carry out drilling during the whole casting process. It is a casting process with little or no drilling, and it is an excellent process technology in the field of casting. Its application range is very wide, not only suitable for casting of various types and various aluminum alloys, but also the specifications and precision and process performance of the produced castings are higher than other casting methods. In addition, investment casting methods can be used for castings that are heat-resistant and inconvenient for production and processing. This type of casting method is more suitable for casting components of high-tech industry chains such as aerospace, defense and security because the whole casting process is not at high temperature and high pressure.

At this stage, inStainless steel precision castingAt the level, a variety of perfect technologies and processes have long been available.

Silica sol shell process. The silica sol shell making process is widely used in the field of relatively top-notch internal combustion engine parts casting. This way The applied paint has good reliability, does not require the whole process of chemical hardening, is heat-resistant, and has a stronger ability to resist deformation. However, the disadvantage of this technology is that it is less mild to wax molds. Although improvements can be made based on the addition of surfactants, it will increase capital investment to a certain level.

Water glass shell technology. The technology is low-cost, the actual operation is relatively simple, and the regulations on raw materials are not high.Stainless steel precision castingThe application is more common. However, compared with the silica sol shell making process, the larger difficulty of this technology is that the process performance of the obtained casting is general, and the specification accuracy is lower. However, due to its cost advantages, this technology is still used in some civilian or low-precision internal combustion engines in China. Since the introduction of this technology, Chinese scientists and technicians have carried out relatively large improvements to it. The specific manifestations are improved shell coatings, improved curing agents, and selection of composite shells.
