Manufacturing technology of self-made spring

Spring processing includes cold rolling, hot rolling and other processing methods, and then it goes through a series of processing procedures such as grinding, shot blasting, heat treatment, setting, coating and packaging.

1. Choose steel wire suitable for your own needs, mainly with moderate thickness (not steel wire, steel wire is elastic, steel wire is not elastic).

2. Burn the steel wire red with fire and naturally cool it. The purpose is to anneal and make the steel wire lose its elasticity.

3. Find a round bar with proper thickness, iron or wood. Wind the annealed steel wire into a spiral shape on a round bar, just like the spring shape you need.

Prepare a pot of cold water, put the unfinished spring water on the fire to burn red, and immediately immerse it in the water. This is quenching, the purpose is to restore the elasticity of steel wire.
