Proof Coil Chain G30 Details

How Is Link Chain Made?

The link chain is produced by the following steps, cutting, forming, welding, polishing and calibrator.

  • Raw Material Incoming
  • Raw Material Treatment (annealing and drawing)
  • Material Preparation
  • Former, Knitting Welding and Burr Removing
  • First Inspection (Auto calibrator, and Printing)
  • Heat Treatment (Quenched & Tempered)
  • Drawing Test Second Inspection
  • Measurement Final Inspection
  • Surface Treatment
