Beyond Just Gears: Your Full-Service Manufacturing Partner
Industrial Equipment
A global leader providing specialized polymer solutions for component design engineers and OEMs across diverse manufacturing sectors. Our application-specific expertise helps shape performance and innovation in four key industrial markets, empowering engineers to overcome complex design challenges with advanced materials technology.
Medical Devices
If you need precision molded component parts then we can also handle your requirements for medical, pharmaceutical and drug delivery. Example parts could be plungers and gears for injection devices, dosing chambers for inhalers, or nozzles for aseptic filling lines. We can process a range of polymer materials depending upon your needs. These include the high performance polymers, like PEEK and also the specific pharmaceutical contact PEEK grade (VICTREX PC) that comes pre-certified with industry relevant testing (USP Class VI, USP 87, USP661.1)
Automotive & Gears
Across all industry sectors, there's a growing demand for cost-effective, high-performing, high-precision gears that operate quietly and reliably—even in the most challenging environments. Our advanced polymer solutions—including our specialized High-Performance Gear product family—have emerged as compelling alternatives to traditional metal components that no longer satisfy evolving customer requirements.
