What are the selection standards of mold steel

Nowadays, the application of molds has involved all aspects of our lives, as large as automobiles, aerospace equipment, as small as daily necessities, mobile phones and other products, as long as the number of products will be applied to mold production. The mold frame is an integral part of the mold, which is equivalent to the skeleton of the whole mold. Therefore, the selection of the mold will affect the quality of the final product.

For example, when the mold is used, the temperature is basically high, so the mold must have a certain high temperature resistance and can withstand a certain pressure. The steel used in the corresponding mold will have strict requirements to ensure the overall performance of the mold.

Selection standard of die steel

1, the mold frame needs to be heat treated to improve its hardness. Because the use of the mold will be subjected to greater pressure and friction, it is necessary to ensure the accuracy and stability of the mold shape and size, in order to ensure that the mold can be used for a longer time. The wear resistance of the die frame is greatly affected by the chemical composition of the steel and the hardness of the heat treatment, so when the hardness of the die frame is increased, it will have more wear resistance.

2, cutting processing will have a long impact on the performance of the mold frame, in order to make the cutting tool can be used for a longer time, to ensure good cutting performance and reduce roughness, in the mold frame must use the appropriate steel.

3, the steel used in the mold must be properly polished to make its surface more smooth, the impurities in the steel can not be too much, and there will be no pitting and orange peel problems when polishing.

Summary: The performance of the mold steel has an important impact on the mold itself, so we must pay attention to the selection standard of the mold steel to ensure that the service life of the mold is long enough.
