Swiss precision

Rumpel SA is an independent, highly successful SME in the screw machining sector. Founded in 1932, the company currently employs a workforce of around 50 people.

Using the most up-to-date equipment, we manufacture smaller and larger production runs, turned parts, shafts and special screws. We produce the required parts according to your specifications, using all current materials, in diameters ranging from 4 to 65 mm and with a maximum length of up to 600 mm.

We process predominantly machining steels, as well as various types of stainless steel and aluminium. Depending on the size and complexity of the production run, we produce workpieces on CNC multi-spindle and turning centres and long-part lathes.

As a certified company in accordance with ISO 9001:2015, ISO 14001:2015 and ISO 13485:2016, we completely fulfil the requirements of a modern quality management system.
