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.

ST2 Innovative Servo Tensioning Creel for High-Speed Winding

ST2 Servo Tensioning Creel

An innovative and compact tensioning creel developed for high speed and accuracy. The configuration of the guide rollers reduces stringer wrap-ups and fuzz. The standard ST2 can hold up to sixteen 9-inch diameter bobbins in an 82”x72”x40” footprint. The system can be customized and is compatible with towpreg and wet winding systems. Learn more

Towpreg Delivery Head

This delivery system provides the same level of control as the wet winding head but with all rolling contacts to work with today’s advanced towpreg fiber systems. Each head is configured for a specific tow width and number of tows.

Tape Tensioner

Shrink tapes, veils, and other spooled materials up to 3″ wide can be tensioned (up to 20 lbs) and placed onto mandrels with the same accuracy as fiber.

Safety Fence

Provides a physical barrier around a workcell to keep operators safe from moving machinery. Safety fences can include interlocked doors for workcell access and be combined with Light Curtains and Foot Controls for customized safety needs.

Safety Light Curtains

Light curtains provide additional operator safety to protect hands, limbs, or bodies from touching moving components inside the work cell. The machinery will stop immediately when a beam is broken, ensuring a safe work environment.

Safety Control Systems

Allow operators to maintain hand contact with the mandrels for tie-on/cut-off system or placing local reinforcement while still being able to rotate the mandrel (forward and reverse) or stop it immediately as needed with foot operation.

Auto Tie-on/Cut-off System

Process automation of fiber tensioning, tie-on, and cut-off operations before and after winding. Significantly reduces process time and manual operations while increasing quality and throughput. Available for wet winding and towpreg systems.

Tailstock Chucks

Solidly support mandrels with the addition of a tailstock chuck. Ideal for unbalanced mandrels or delicate mandrels that may not withstand the axial force of a live center. The mounted chuck can be easily swapped with a tailstock live center for mandrel supporting flexibility.
