Tooling design is necessary to create thermoformed parts, but prototyping costs time and money. That’s why it’s important to do thorough planning to avoid unnecessary rounds of prototyping. We use design and CAD/CAM software including Solidworks, Mastercam, and Unigraphics to plan the smart way. This minimized the number of iterations needed to design a successful product.

What is CAD/CAM software (such as Solidworks, Mastercam, and Unigraphics)?

Computer-aided design (CAD) allows engineers to design and predict product outcomes using modeling. The software programs offer structural, thermal, fatigue, and dynamic simulation. In addition, CAD improves the end result in terms of dimensions and material consistency. After a model is created with CAD, our engineers take that model and input the information into computer-aided manufacturing (CAM) for the purpose of controlling the manufacturing process.
