We deliver your special parts according to requirements: Collar studs, parts with shoulder, stepped bores as well as parts with female/male threads
Cold extrusion parts (cold formed parts): precision formed connecting elements at a low unit price
The automotive industry, mechanical engineering and other high-tech industries have a strong demand for precision formed connecting elements of any different kinds. At the same time, these parts are subject to high price pressure.
Thanks to our highly modern cold forming and extrusion technology, we can also manufacture complex parts which, in the past, could only be produced at great effort and expense on lathes, as low-cost cold extrusion or cold formed parts.
We specialise in collar studs, parts with shoulder, stepped bores as well as parts with female and male threads – in steel, high-grade steel, brass, copper or light metals.
For smaller batch sizes, we recommend the manufacture of low-cost blanks as cold extrusion parts. The respective special forms are produced by further cutting processes.
Forming takes place on extruders without heating, in one or several stages, for solid parts and for hollow parts. Screws and bolts in double-stroke and multi-stroke range.
Cold extrusion parts, resp. Cold formed parts: Low-cost production for batch sizes from 30,000 pieces. Also suitable as blanks for further cutting processes for special parts. All products are sorted machine-compatibly on request. Criteria and PPM figures can be defined commonly.
