ODM heavy duty Metal Spiral Torsion Coil Spring For Garage Door

Customized OEM ODM Metal Spiral Torsion Spring For Spring Toy

Description

Torsion Spring is a complex design principle among all types of springs and the type change is quite lively, so the theory involved in the design is the most complicated. Each ring or close or separate around, can be suitable for torsion load (at right angles to the spring axis). The end of the spring can be wound into a hook or straight torsion arm.

Torsion spring production process:
spring wire → spring winding → low temperature stress relief annealing → high temperature degreasing → washing → dilute hydrochloric acid washing → washing → electric galvanizing (80 min) → washing → blanking → dehydrogenation treatment (200 ℃, 4 h) → feeding → washing → color passivation → washing → drying → blanking → inspection
