Ultem CNC Machining Service

Ultem (polyetherimide) combines exceptional heat resistance (continuous use up to 340°F / 170°C), high mechanical strength, and inherent flame retardancy (UL94 V-0) with very low smoke and toxic gas emission. It machines reliably to tight tolerances of ±0.001″ (25 μm), delivers smooth finishes, and maintains dimensional stability under load and thermal cycling—making it the go-to choice for aerospace brackets, medical sterilizable instruments, electrical connectors, semiconductor wafer handling components, fuel system manifolds, and structural parts exposed to elevated temperatures or harsh chemicals.

Operating from an ISO 9001:2015 certified facility, we precision-machine virgin Ultem 1000 as well as reinforced grades (glass-filled, carbon-filled, bearing grades) with optimized tooling and fixturing to minimize internal stresses and achieve consistent repeatability from fast-turn prototypes to high-volume runs. The result is robust, lightweight components with superior dielectric strength, excellent chemical resistance, and the ability to withstand repeated autoclave sterilization or exposure to aggressive fluids—trusted in medical, aerospace, electronics, and industrial sectors where failure is not an option.

Ultem outperforms many alternatives (such as PEEK in cost-sensitive applications or polycarbonate in high-heat scenarios) by offering a unique balance of high stiffness, creep resistance, radiation stability, and compliance with stringent flammability and biocompatibility standards. Our advanced CNC capabilities handle its toughness to produce complex geometries, thin walls, and precise features with outstanding surface quality and no moisture-related dimensional drift—ideal for flight-grade insulators, reusable medical trays, high-temperature sensor housings, burn-in test sockets, and load-bearing components in demanding environments.
