Custom Spring Steel Industrial Usage Compression Wire Forming Spring
Wire Forming spring using the elastic effect of the data made of
parts, under the effect of external force can attack deformation,
remove the external force and restore to original state. The size
of the elasticity of linear spring has a close connection with its
density processing.
The roughness of the end face of the linear spring should not be
less than 12.5μm. The two ends of the ring and the special-shaped
spring supporting ring are not less than three-quarters of the
circumference, and the thickness of the end is usually not less
than 1/8 of the diameter of the steel wire.
Wire forming 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 → → feeding → washing → color passivation →
washing → drying → blanking → inspection
