The mold spring is mainly a kind of raw material used by zipper machinery for some injection molds, metal materials, plastic machinery, die-casting molds, and other ductility, fitness, sports, high-precision equipment, machinery and equipment, cars and other industries. Generally, the key material is chrome carbon steel. Furthermore, the die spring not only has the advantages of heat resistance and strong rigidity in the whole application process, but also can increase the overall service life of the die spring. So, what must be paid attention to when applying reliable die springs?

1. Because it is very easy to change to the application close to the periphery when the mold spring exceeds 300,000 standard, and the close proximity to the periphery can make the number of coils gradually close, and it is very easy to cause the spring yellow parameter to increase, and because of the compliance The uniqueness of standing up like the picture and becoming high ground stress is very prone to loss conditions, so the standard of 300,000 should be prevented from being exceeded.

2. Because if there is a gap in the mold spring, it will increase the severity of the plastic packaging products, and it is very easy to lose more and more precision mold processing. In the whole process of application, an early reduction amount exceeding one millimeter should be carried out.
