Precision machined components for the hydraulic sector
PSI specializes in precision machining for the hydraulics industry.
PSI produces barrels, port plates, friction washers, as well as valves, blocks and distributors, for hydraulic pumps and motors. Our experience of flat lapping, as well as our specific expertise in precision machining, tailored to the requirements of the hydraulic sector enable us to guarantee an optimum service for our customers. Starting from customer’s technical drawing, we manufacture in medium and large series.
Our experience and our deburring equipment are valuable assets.
Dimensions : from Ø40 to Ø900 mm
Examples of machining parts manufactured for the hydraulic sector
Machined parts in steel, cast iron, brass, bronze for motor or hydraulic pump type:
- Distribution ice
- Friction washer
- Block and distributor
The different steps of part machining for the hydraulic 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 in-house manufacturing process: sawing, turning, milling, cutting, induction hardening, grinding, lapping allows us to guarantee parts with very high added value (location, position, parallelism, precise surface finish, etc.)
We machine all types of metals and have a perfect knowledge of foundry parts – FGL or FGS cast iron – or forging, brass, bronze, bi-metal and also all types of supplies such as bars or tubes.
The diversity and versatility of our machine park allows us to adapt to the majority of industrial needs.
Our experience as well as the complementarity of our machine park (turning, machining centres, induction hardening, grinding, flat 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.
