Machined parts for automotive injection system
We produce parts for injection, especially safety valves
Indeed, we are a leading manufacturer of pressure limiters for injection systems.
We can guarantee a “metal-metal” waterproofing under pressures of up to 2,800 bar, by having surface roughness and geometrical defects under control.

We manufacture bar-turning parts for injection industry:
