Since 1969, Westec Plastics Corporation has set the standard for the custom plastic injection molding industry. We specialize in tight tolerance mold manufacturing and production. Quality and customer service are our top priority and 100% customer satisfaction is our goal. Our dedication to both quality and our customers is why Westec Plastics is the leading Bay Area molding company.
Westec’s engineering design team can take your project from concept to design by supporting customers with design for manufacturability and mold flow analysis. Westec has a full-service tool room that can assist you with mold design, prototypes, and mold manufacturing.
Our 23 state-of-the-art injection molding machines range in size from 39 to 610 tons, including 3 two-shot injection molding machines, all of which are integrated into our Real Time Monitoring System. This allows Westec to track mold performance and efficiency during production. ISO Class 8 clean room facilities are also available for medical and other applications that require an extra degree of cleanliness.
In 1969, our founder Paul Biery returned from the Vietnam War to start Westec Plastics with his wife Karen. Paul was a toolmaker by trade, and wanted to be able to sample his tools in-house. He purchased his first machine out of a farmer’s barn in Gilroy, California that year – pretty soon, Westec Plastics was born.
