Spring Wire Produce Process
- Wire rod
Raw material for steel wire products is supplied by steel mill. Steel mills make wire rod by hot rolling process from billet.
- Surface treatment
Descaling wire rod removes rust and scales on the surface of wire. Surface coating wire rod facilitates drawing.
- First Drawing
Descaled and surface coated wire rod is brought to 1st drawing machine to draw to required diameter and to give mechanical properties suitable for application.
- Patenting
Heat treatment to transform wire into required microstructure and to facilitate drawing.
- Intermediate Drawing
Intermediate Drawing after 1st drawing.
