Services
Injection Molding
We provide full-scale injection molding services for production and prototype parts using advanced thermoplastic resins. Our 28 machines handle clamp forces from 28385 tons with shot sizes up to 24 ounces. This capability supports clients in medical, industrial, and consumer sectors requiring precision components with tight tolerances.
Medical Device Molding
Our ISO 13485:2016-certified processes produce critical medical device components from biocompatible materials like PPSU and PEI. We meet stringent regulatory requirements through documented quality controls and steam-sterilization-resistant polymer processing for surgical instruments, diagnostic equipment, and disposable devices.
Engineering Resin Processing
We specialize in high-performance thermoplastics including PEEK, Victrex PPS, and Ultem PEI. These materials withstand extreme temperatures, chemicals, and mechanical stress for aerospace, semiconductor, and harsh-environment applications. Our team optimizes processing parameters to maintain material integrity during molding.
Prototype Tooling
Our Prototype Plus Frame System creates cost-effective steel tooling for early-stage development. This approach balances durability with rapid iteration cycles, allowing clients to validate designs before committing to full production molds with MUD or DME base systems.
Insert Molding
We integrate metal or plastic inserts into molded parts during production, reducing assembly steps for clients. This process enhances part strength and functionality for applications requiring embedded components like threaded inserts or electronic housings.
