Case Study: One of our most tolerance-critical projects — a compressor magnet housing for commercial HVAC compressors

Using our unique filament-winding process, our engineers made housing from a continuous tow of carbon fiber for maximum hoop strength in magnetic-bearing HVAC equipment.

Our client came to us, asking for a prototype that would provide a strong yet lightweight housing for magnetic bearings while rotating at high RPMs.

This was no easy task, but our engineering team collaborated with the client to design and fabricate a magnetic-bearing HVAC housing component that performed beautifully. The finished product met all design specifications, including a 4-decimal place form tolerance for cylindricity.


Customer supplied Composite Resources with design specifications, 2D detailed drawings and 3D CAD models 


  • Filament Winding
  • Tape Wrapping
  • Out of Autoclave oven curing
  • CNC Turning
  • Finish coating
  • CMM inspection


This project initially began as a prototyping endeavor, but evolved into a full-production product as we collectively developed a solution to meet the ever-growing demand for energy efficient HVAC compressors.

We're proud of our involvement with this unique and highly useful solution, and we're eager to assist you with any of your own prototyping or production needs. Contact our team today to see how we can help turn your idea into reality.
