Material-first engineering for sterilization-critical applications
This range of PPSU (Polyphenylsulfone) medical device housings is engineered from a high-performance amorphous thermoplastic chosen for one reason: it survives what ordinary plastics cannot. PPSU combines outstanding toughness, high-temperature resistance and broad chemical compatibility with excellent optical clarity in its natural amber tone — the ideal housing material for surgical instruments, diagnostic devices, sterilizable enclosures and fluid-handling equipment.
Each housing is CNC-machined from solid medical-grade PPSU stock, allowing us to hold tight tolerances on fine features — seal grooves, optical windows, threaded ports and thin walls — without the tooling cost and lead time of injection moulding. This makes it equally suited to rapid prototyping and low-to-mid volume production.

PPSU (Polyphenylsulfone) is a high-performance amorphous thermoplastic offering exceptional toughness, high-temperature resistance (continuous use up to 180 °C) and excellent optical clarity. It is biocompatible (USP Class VI / ISO 10993) and resists thousands of sterilization cycles, making it a benchmark material for reusable medical housings and surgical instruments.
PPSU is engineered to withstand 1,000+ steam autoclave cycles at 134 °C without cracking, discoloration or loss of mechanical properties. It is also compatible with gamma, EtO and plasma sterilization, giving you flexibility across hospital protocols.
Standard dimensional tolerance is ±0.02 mm, with ±0.01 mm on critical features. Surface finishes range from Ra 0.4 to 1.6 µm, and we offer optical polishing for transparent windows and fluid-viewing sections.
Yes. We machine the full range of engineering plastics — including PEEK, PEI (Ultem™), PC, PMMA, POM, PTFE and nylon — as well as aluminum and stainless steel. We can also assist in selecting the optimal material for your specific application.
We accept STEP, IGES, STL and 2D PDF/DWG drawings. Prototypes are typically delivered within 5–10 working days, with low MOQ for custom projects. Provide your drawings and target quantity for an accurate quotation.
