Spring Manufacturing Equipment

Coil Spring Manufacturing Equipment

Our coil spring manufacturing machines can produce various types of coil springs.
These coil springs are used for automobiles, trains and heavy machines.
We have made the machines for wire diameter up to 100mm.

STEP 4 セッチング


Setting Machine

The purpose setting process is to improve fatigue strength of coil springs, and enhance its elastic limit. Setting process can identify "specified load" or "specified height" of coil springs.

Cold Setting UnitB663S


This is an equipment to make a setting of coil springs after shot peening in a normal temperature two by two. The machine has a function to cool a coil spring, which is peened in a hot condition. Coil Springs after setting are hooked to hanger conveyor for painting. Jigs, which are changed in accordance with shapes, can be automatically changed by jig changer (Option).

  • Cooling Device by water
  • Setting Machine
  • Jig Changer (Option)
  • Hooking Device (to painting hanger)
  • Positioning Device and Transfer Device
