Red mold spring:

Red mold spring compression deformation in 25.6%, 28.8%, 32% range, mold spring is a heavy load compression spring, made of rectangular section steel wire, rectangular section mold spring compared with circular section spring, in the same space the use of rectangular section spring cross-sectional area is large, so its stiffness is large, can be used as a heavy spring. The stiffness of the die spring with a rectangular section is also close to a straight line, so the stiffness is relatively stable.

A glance at the national industry standards of Elastic Yellow

Originated in the early sixty years, it has been 40 years. The butterfly spring has already produced a sound quality standard system. At present, there are 22 national industry standards and 30 national standards of the bomb. In 1998, the General Administration of Quality Supervision, Inspection and Quarantine allowed the establishment of the technical Association of missile and Arrow standardization across the country (SAC/TC235), and the standardization of missile and arrow has been promoted in an all-round way. In 2004, ISO/TC227 (bullet and arrow) was established internationally. In the real identity of Chinese members, this means that the standardization of torsion spring Chinese bullets has entered a new link, namely; All-round tracking and practical participation in the work.
