Hot Coiled Spring Production Line

The hot-coiled spring production line is engineered for the complete manufacturing process of coil springs (automotive suspension damping springs), covering material cutting, induction heating, coiling, heat treatment, and hot-setting — with each stage seamlessly automated and integrated.
The core heating unit utilizes medium-frequency induction heating technology, delivering rapid and uniform temperature distribution. It accurately heats spring steel billets (e.g., 60Si2Mn) to the required forming temperature while controlling decarburization depth (≤0.1mm) to ensure superior surface quality of the finished spring.
The line incorporates two key modules — a tip-grinding induction heating unit and a hot-coiling induction heating unit — addressing end-taper processing and full-body coiling respectively, accommodating various spring specifications.
With a high degree of automation, the line minimizes manual intervention and delivers stable, efficient operation. It has been widely deployed in the automotive components industry and earned strong recognition from customers.
