About Westec Plastics Corporation
Westec Plastics Corporation was founded in 1969 in Livermore, California, in the San Francisco Bay Area. The company began when Paul Biery, a toolmaker returning from the Vietnam War, purchased his first injection molding machine from a farmer's barn in Gilroy with his wife Karen. Westec operates a 46,080-square-foot facility housing 23 injection molding machines ranging from 28 to 610 tons, including three two-shot machines. Its capabilities span precision injection molding, clean room manufacturing (ISO Class 6, 7, and 8), insert and overmolding, in-house tooling with a Makino F3 vertical machining center, Agie Charmilles FORM 20 EDM, and Mantle 3D-printed steel tooling. Secondary operations include vibration welding, ultrasonic welding, laser engraving, pad printing, and automated assembly with cobots. Advanced metrology includes a Keyence IM-7030T instant measurement system, Micro-Vu and Mitutoyo CMMs, and statistical process control. The company serves medical device, biotech and pharmaceutical, electronics, aerospace and defense, consumer, and food and beverage industries. Customers include medical device companies such as those represented by Sandy G. and Sara N., and a biotech diagnostics firm cited by Victor B. Westec differentiates itself by combining advanced tooling, flexible domestic and offshore sourcing, and in-house manufacturing to accelerate production while maintaining tight tolerances and regulatory compliance. Its ISO 13485:2016 certification supports regulated programs requiring DNA-free molding and full validation documentation.
