Engineering capabilities span the entire product cycle, from conceptual design through analysis, materials and processes, qualification testing and production support.

Product Solutions

Dish Assembly
System Solutions

Product concepts are transformed into successful results working independently or in collaboration with the client.

Composite designs are created to perform key roles in the performance of systems, interacting with other components to meet challenging operating requirements. Integrated solutions are achieved by blending technical creativity with an ability to relate composite material characteristics to system performance.

Design and Automation

Solid Modeling - Tank Assembly
Solid Modeling
CNC Toolpath Simulation
CNC Toolpath Simulation

A proven design process is employed to tackle the toughest composite product design challenges. It draws upon our unmatched ability to blend product concepts with a thorough understanding of material behavior, manufacturing methods and analytical techniques.

Solid modeling captures the general arrangement within form, fit and function objectives, while detailed design, analysis and producibility iterations refine the configuration. 3D design models are linked with 5-axis CAM software to simulate automated manufacturing methods and produce prototype tooling and test articles. Laser scanning and CMM inspection data are compared with design model data to verify prototype dimensional tolerances.
