Why can we call the products obtained by precision casting and by casting? The answer is precision casting. Moreover, from the current point of view, its application is more and more extensive, can be said to penetrate all the industrial sectors, especially in the fields of electronics, petrochemical, energy, textile and so on.

For precision casting products, tempering is necessary because it can improve the service performance and internal quality of the workpiece. Precision casting is also called lost wax casting. Its products are precise, complex and close to the final shape of the parts. It can be directly used without processing or little processing. It is an advanced technology of near net shape formation. The key (explanation: an important part of things) lies in the reasonable selection of materials and forming process, and the second is to do a good job in heat treatment. Moreover, it is also beneficial to the mechanical, physical and chemical properties of castings, so let's talk about it in detail.

The main points of heat treatment process of precision casting are as follows:

(1) The tempering process shall be strictly followed and implemented, and no illegal operation is allowed. Precision casting is also called lost wax casting. Its products are precise, complex and close to the final shape of the parts. It can be directly used without processing or little processing. It is an advanced technology of near net shape formation.

(2) In order to prevent the deformation and fracture of some parts which are easy to change, we can add the support bar.

(3) It is necessary to control the tempering temperature, neither too high nor too low, so as not to affect the tempering effect.

To do these three points well, we can basically do a good job of heat treatment and get good results. I hope you can pay enough attention. Precision casting refers to the process of obtaining precise size castings. Compared with the traditional sand casting process, the precision casting has more accurate dimensions and better surface finish. It includes: investment casting, ceramic mold casting, metal mold casting, pressure casting, lost foam casting.
