To ensure the perfect fit of your parts, threading is one of HEMA’s unique selling propositions. Depending on the production requirements, we rely on different processes (flat-die process, roll-to-roll, roll-segment).


Grooves, sharp edges, or cross holes: Not all geometries or details can be (exclusively) produced by cold massive forming. Where necessary, we can also bring parts to perfection by further cutting processes (milling, turning, drilling).

HEMA - knowing it fits!

We work according to certified processes and highest quality standards, with reliability and sustainability being the central guidelines. This ranges from the quality of our products, deadlines and deliveries up to energy management and environmental protection. HEMA already thinks into the future. Something you can rely on.
