Westec Plastics Corporation

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 Northern California/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’s full-service toolroom can assist with mold design, prototyping, and mold building. Westec recently invested in state-of-the-art technology for 3D steel printing of tooling inserts to better meet their customer’s needs.

Our 23 state-of-the-art injection molding machines range in size from 28 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.
