Precision machined components for the automotive sector

PSI specializes in precision machining for the automotive industry.

We manufacture parts such as crankshaft gears or bearing rings in large series.

Our objective: to ensure a partnership of industrial excellence by knowing how to guarantee process performance and co-development solutions.

Our experience in robotic integration for the manufacture of rework products such as forgefoundryand plots is an important asset. 100% integrated control is also part of our specifications.

Dimensions : from Ø40 to Ø250 mm

The different steps of part machining for the automotive sector

We work according to the requirements of large contractors and proceed to the prototype, initial samples, PPAP phases then launch into series production and transmission of control reports.

Our control process includes a validation phase at the start of series, automatized control in production then final control before shipment (editing and transmission of a control report).

Our experience as well as the complementarity of our machine park (turning, machining centresinduction hardening, grindingflat lapping, etc.) allow us to offer complete services through a partnership capable of providing technical and economic solutions by offering adaptations, different sources of supply (forging, foundry, laser cutting, flame cutting, etc.)

Integrating the entire production chain internally ensures responsiveness, technical mastery and quality, and proposals for economic optimization.
