Filament Winding Accessories

Engineering Technology Corporation has been supplying filament winding machines, equipment, and accessories to the filament winding industry for over six decades. The company’s primary focus is customer satisfaction through the development of complete solutions, excellent performance, and the best outcome of each filament winding project.

As a global expert in filament winding, Engineering Technology Corporation knows all about filament winding and provides everything needed to optimize any filament winding workcell’s performance and safety. From resin baths to delivery heads and every fiber contact point between, Engineering Technology Corporation has a product to make the filament winding process reliable and user-friendly. Whether increasing operator safety with light curtains, improving fiber wet-out with an upgraded resin bath, or adding capability such as tape dispensing, every piece of accessory incorporates Engineering Technology Corporation’s decades of experience and innovation.

STANDARD WET WINDING DRUM RESIN BATH

A 6.5″ wide drum can handle up to 20 tows and a 1.5-liter resin pan for production work. A heating option to warm up the resin is available.

WET WINDING DIP RESIN BATH

Supports resin impregnation for up to 60 tows. Adjustable drag bars and squeegees provide reliable resin content control. Ideal for applications requiring wide fiber bands or operations that use center-pull spools.

Delivery Systems for filament winding (Towpreg & Wet Winding)

DELIVERY SYSTEMS (TOWPREG & WET WINDING)

Delivers fiber from the tensioner to the delivery head, minimizing contact points and maximizing control. Each delivery system is customized for facility layout, fiber type, and number of tows.

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.

WET WINDING DELIVERY HEAD

The standard configuration provides flat bars, a comb, and a D-ring to adjust the fiber bandwidth and thickness. Custom D-ring radii, pin count, pin spacing, and additional fiber band adjusting options are available.

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.

FILAMENT WINDER CASTERS

Allows to easily turn and move a machine in restricted spaces. Enable the technicians to move as well as lock work stands with minimal effort.
