Bending and forming machinery

Modern bending and forming machines produce complex wire parts in a single cycle—from straightening and cutting to 3D coiling and profiling. CNC spring coilers with 2–7 axes manufacture compression, tension, and torsion springs, while multi-formers handle intricate geometries like double torsion and custom-shaped profiles.

Cold heading machines enable high-speed, high-strength production of bolts, screws, and rivets without heating the material—preserving grain structure and mechanical properties. Thread rolling machines form threads by cold forming, significantly improving fatigue resistance compared to cutting.
