PSP Injection Plastique

PSP manufactures thermoplastic components using injection moulding for custom industrial applications. Its Muret production team supports small and medium production series and controls the process from sample approval through serial deliveries. The company also manages product traceability and statistical production monitoring.

PSP supplies technical plastic parts engineered to meet functional requirements in automotive, aeronautical, medical, leisure and building applications. Manufacturing projects may combine moulding with secondary machining and finishing. The company works with customers to optimise part feasibility and industrialisation before production.

The team participates in early-stage product and process studies, helping customers assess manufacturability and optimise designs. PSP considers the interaction between component geometry and mould construction to improve technical feasibility and manage tooling cost. These engineering activities continue through prototype evaluation and initial sample acceptance.

PSP supports development projects with prototyping and validation prior to series manufacturing. Its in-house tooling and machining resources can support iterative changes to moulds or plastic components. Prototype work is integrated with the company’s small- and medium-series industrialisation approach.

PSP designs and manufactures injection moulds ranging from prototype tooling to series-production moulds. Its machining workshop uses milling, turning, grinding and erosion equipment, and the company specifically highlights aluminium mould construction. Tooling can be developed alongside the moulded plastic component to balance functional requirements and manufacturing cost.

PSP offers pad printing to mark or decorate moulded plastic components after production. The process supports monochrome and coloured graphics where the customer requires a finished, ready-to-assemble or market-ready appearance. The company also lists hot stamping as a complementary finishing technique.

PSP provides secondary operations and subassembly services in its finishing workshop. Components can be joined or fixed by clipping, adhesive bonding and ultrasonic welding, depending on the product specification. These operations help customers receive assembled plastic products rather than separate individual mouldings.

Ultrasonic welding is among the assembly processes explicitly offered by PSP for joining compatible plastic elements. This capability is used alongside clipping and bonding in its rework and finishing workshop. The company integrates the joining step into the delivery of ready-to-use plastic subassemblies.
