What our Customers Say

  • I don’t give out excellence every day, but we are very pleased with Westec. We appreciate and respect them for what they know and what they do. They’re solid and honest in their mold design advice and project planning.

    Sandy G., Medical Device Company

  • I love the team. They’re very friendly which is their best attribute. They’re easy to work with – down to earth and deliver with a family business feel, that’s really a strength of theirs. They’re well-rounded in terms of balancing quality, processing, and competitive in all those aspects.

    Sara N, Co-founder, Medical Device Company

  • A quick reply or RFQ for our early stage development is important. We find companies that support our needs with the shortest lead times for tooling and components. Westec fills this need for us. Their professionals ensure they produce high quality parts and they work closely with us to ensure we are satisfied with service, documents, and components. They’re a pleasure to work with.
