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
Performance factor
Performance factors: spring stiffness, maximum deformation, maximum load and spin specifications.
Spring stiffness is the angular return torque per unit of angular displacement.
Maximum deformation refers to the maximum deformation of the spring before damage.
Torsion spring rotation is right, left and double.
