Details of cooling operation in precision casting processing

The scope of application of precision castings is getting wider and wider, and there are more and more processing techniques. Among them, the cooling process is an indispensable process. Some of them have to undergo solid-state phase transformation of alloys. During the phase transformation, the comparison of metals changes, such as The volume of carbon steel decreases from the δ phase to the γ phase, and the volume increases when the γ phase undergoes eutectoid change.

A good solution to the problems faced by domestic precision casting products

The level of technology is low, and the quality of precision casting products is poor. 1. The problem of cracks in castings is serious. 2. Large castings have serious segregation and inclusion defects. After the solidification of large steel castings and large steel ingots, there are problems of macro segregation and coarse grains at the root of the riser and the thick section of the casting. 3. The application of simulation software is not popular. Casting process simulation is a necessary part of casting production. In foreign countries, if there is no computer simulation technology, it is impossible to get orders. The level of technology is low, and the quality of precision casting products is poor. 1.

Development of precision casting

Precision casting is also called lost wax casting. Its products are precise, complex, and close to the final shape of the parts, and can be used directly without or with little processing. Therefore, investment casting is an advanced technology near net shape.

How much is the development prospect of precision casting related to the automobile industry?

Precision casting is an important link in the automobile industry chain. About 20% of the spare parts in the manufacture of a vehicle are castings. As a downstream industry in the automobile industry chain, precision casting mainly provides cylinders for various major systems. Blocks and pipes, such as cylinder blocks of engines and transmissions, intake and exhaust manifolds, etc. Of course, many precision casting companies are not necessarily linked to the automobile industry, and now many industries also need castings.
