2021/10/22 679

The mold core refers to the precision parts used for the key operation of the center part of the mold. The general structure of the mold core is extremely complex, the processing is very difficult, the cost is high, and the labor expenditure for manufacturing often exceeds the material itself. The choice of mold core material is directly related to the cost of the mold and the service life of the mold.


Why choose optical mold core?

because the choice of material quality directly affects the service life and cost price of the whole set of molds in the later period.If the demand for the product is large and the mold core is made of poor quality materials, the mold may be scrapped before the production demand is reached, and the mold needs to be re-developed, which will ultimately affect the company's production efficiency, and the secondary processing will increase the cost of the mold.

If the demand for the product is small, choose good quality materials to make the mold core, although the good use of the mold in the production process is ensured, but the production capacity of the mold has not been fully utilized, the production demand has been exceeded, and the company's cost is excessive. , Is also a waste


So what are mold core material?

Common mold core materials include P20, 738, 738H, 718, 718H, NAK80, 2316, 2316A, S136, etc.

According to the customer's demand for hardening the mold core, the following materials can be selected: 2344, 8407, SKD11, SKD61, etc.


The following is our company's Japanese customer case

Accuracy requirements: ±0.005mm
