Custom-machined Ultem® (PEI) sterilization trays made to your exact size, hole pattern, and instrument layout. Autoclave-ready. Built by Enplas.
When trays cycle through steam autoclaves and low-temperature processes day after day, material choice decides longevity. Ultem® (PEI) combines a high glass-transition temperature around 217 °C, exceptional hydrolytic stability, and chemical resistance so trays resist creep, warpage, and whitening even after repeated sterilization. Select healthcare grades are compatible with steam (up to ~134 °C), vaporized hydrogen peroxide (VHP) gas plasma, EtO, gamma, UV-C, and e-beam methods.
Historic application literature for Ultem® specifically lists sterilization trays among typical reusable medical uses, underscoring its track record in clinical environments.
Because Enplas machines trays from our own extruded Ultem® stock shapes, you are not bound by mold sizes. We produce the exact outer dimensions, wall thickness, and corner radii your instrument set needs, with:
Ultem grades’ sterilization resilience and dimensional stability make them ideal for thin-wall sections and long, flat surfaces that must stay true through many cycles.
Our engineering team designs for sterilization realities: steam access, shadowing, drain paths, and low-stress corners. We recommend fillets, ribbing, and hole patterns that balance stiffness with flow—and we’ll guide grade selection, e.g., unfilled Ultem® 1000 for clarity and toughness vs. glass-reinforced varieties for extra rigidity. Healthcare-focused Ultem® HU grades are noted for repeat-cycle compatibility in steam and VHP and offer biocompatibility options (ISO 10993 / USP Class VI) where required.
Because we control the value chain—extrusion of stock shapes + CNC machining—you get lot traceability, consistent flatness, and finishes tuned for easy cleaning. Our PEI machining methods manage heat and chip evacuation to keep edges smooth and reduce stress, preserving tolerance over the tray’s service life.
Whether you need a compact endoscope cassette or a full OR set carrier, Enplas can deliver made-to-size Ultem® sterilization trays that survive harsh cycles without giving up precision. Send us your instrument list or CAD, and we’ll return a manufacturable design, material recommendation, and firm lead time.
