Injection Molding for Cupertino, CA.

Custom plastic parts and enclosures, from prototype tooling through full production molds.

Our injection-molding bench covers everything from aluminum bridge tooling for 50-500 piece prototype runs to hardened steel production molds rated for 1M+ cycles. Resins span commodity polymers (ABS, PP, PE, PS), engineering grades (PC, PC/ABS, nylon 6/6, glass-filled nylon, POM/Delrin, PBT), high-temp materials (PEEK, PEI, PPS), and medical-grade USP Class VI resins. Process capabilities include 2-shot molding, insert molding for threaded inserts and electrical contacts, overmolding for soft-touch grips, and gas-assist. Tolerances follow DIN 16742 with critical-feature tolerances tightened on a part-by-part basis. Secondary processes — pad printing, laser marking, ultrasonic welding, sub-assembly — are coordinated as part of the program. We match each project to a tooling and molding source sized for the volume: a Tier-1 production molder for 100k+ annual parts costs more per cavity but pays back; a quick-turn prototype molder gets you to first-article in 2-3 weeks.

When we route a injection molding RFQ for a Cupertino customer, we evaluate the project against partners on three axes: certifications (does it need ISO 13485 for medical or IATF 16949 for automotive?), volume (prototype, low-volume, production), and lead time. Cupertino-area programs typically run on aggressive cost targets and high cosmetic standards — our bench includes Asian production partners with consumer-grade tooling discipline plus US prototype shops for early builds.

For consumer electronics programs in Cupertino, we typically shortlist 2–3 partners and surface real quote comparisons within 24–48 hours.
