SM Filament Winder

  • Robust single spindle winder for a wide range of applications
  • Ideal for medium envelope part production
  • Up to 5 axes of motion in a portable design

Medium-Scale Production

The SM filament winding machine is ideal for medium envelope part production. Economical and portable, the SM filament winder increases capacity to a medium-sized part allowing for full-scale production. With a single spindle and up to five total axes, this machine is ideal for low-volume part production or part development. The winder can be placed on casters for easy relocation. The SM is greatly suited for any pressure vessels, including CNG and CHG tanks. Composite part manufacturing is streamlined with an easy-to-use interface and winding software: FiberGrafiX®.

The SM filament winder is a standardized filament winder with all the standard product line benefits such as optimized price, reduced lead time, and trusted reliability. This model may be customized and automated to any level of customer needs.
