Cross use of stainless steel precision casting technology

Cross use of stainless steel precision casting technology

Stainless steel precision casting, also known as investment casting, is a casting process that minimizes or eliminates cutting during the casting process. It is a widely applicable casting method with high dimensional accuracy and excellent surface quality. At the same time, the casting process is not under high temperature conditions, making it suitable for casting components in high-precision and cutting-edge industries such as aerospace and national defense. Today, precision casting manufacturer Yufeng Metal will have a detailed discussion with you about the cross use of stainless steel precision casting technology.

1. Cross use with rapid prototyping technology:

The cross use of science and technology is mostly complementary. The design and mold manufacturing process of wax molds in stainless steel precision casting is complex and time-consuming. However, rapid prototyping technology can effectively overcome this disadvantage. Using rapid prototyping technology alone is because material limitations cannot be implemented. Therefore, in recent years, many use polymer technology to obtain circular castings, manufacture wax molds, and put them into stainless steel precision casting. For example, photopolymerization stereolithography (SLA) and selective laser sintering (SLS), which are currently mature technologies used in conjunction with investment casting, SLA technology can provide high dimensional accuracy, especially the accuracy of the outer surface of parts, SLS has slightly cheaper raw materials to a certain extent, but its accuracy is also lower than that of SLA technology, making it suitable for some casting work with cost requirements. However, in the process of use, it is still important to pay attention to the key integration points between rapid prototyping technology and stainless steel precision casting technology, such as cost control and casting accuracy of parts, and comprehensive consideration. Choosing the appropriate balance point is a key issue in the combination of rapid prototyping technology and investment casting technology.

2. Computer technology:

The scheme design and optimization work in stainless steel precision casting process is a relatively labor-intensive and time-consuming task. In recent years, with the continuous development of computer technology, many industries that require a large amount of calculation and precision calculation have introduced computer work, and corresponding calculation software has been developed, such as ProCAST Various software such as AutoCAD, AFSolid, Anycasting, etc. can calculate or simulate the design and casting process of stainless steel precision casting, and optimize the current plan through data calculation, playing a good role in promoting the development of stainless steel precision casting.
