Turned part for injection system

Joseph Martin, a specialist in bar turning since 1946 in the Arve Valley in Haute-Savoie (74), France, ensures the control of surface conditions and geometric defects, allowing us to guarantee « metal-to-metal » seals under pressures of up to 3,000 bars.

Our components can be mounted on both hybrid and electric technologies.

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.
