Heavy Duty Impact Specification Large Alloy Compression Coil Spring
Compression spring is a kind of hardware fittings with spiral geometric shape formed by wire, so it is more difficult to harden and strengthen the work than the plane hardware fittings (such as stamping parts).
In addition, it is also necessary to strictly control the hardening effect of the cross section of the compression spring, so as to fully control the fatigue fracture resistance of the decompression spring after use
