High-Speed Winding

The CXG filament winding machine is ideal for high-volume automotive applications. This machine is designed specifically for high-speed CNG and CHG tank production for the automotive industry. Driven by dual motors, the lightweight carriage will reach speeds up to five m/s allowing for industry-leading fiber payout speeds for accurate towpreg or slit tape application. The CXG winder can meet and exceed the industry-leading fiber payout speeds (5 m/s), especially in combination with the ST2 high-speed tensioning creel. Composite part manufacturing is streamlined with an easy-to-use interface and winding software: FiberGrafiX®.

The CXG filament winder is a standardized filament winder with all the standard product line benefits such as optimized price, reduced lead time, trusted reliability, and flexibility for future expansion. This model may be customized and automated to any customer requirement level.
