Coiled Spring Pin Manufacturing Process

STEP 01

Coiling

Spring steel strip is precisely rolled into multiple concentric layers to form the characteristic coiled structure. This process creates the flexibility and shock-absorbing performance required for reliable fastening applications.

STEP 02

Heat Treatment

Controlled heat treatment improves hardness, elasticity, and fatigue resistance. The process helps maintain consistent spring performance under repeated installation and operating loads.

STEP 03

Surface Treatment

Natural Finish + Protective Lubrication
Electroplating, phosphating, or other plating/coating treatments, followed by hydrogen embrittlement relief to prevent hydrogen embrittlement.
