SC+ Filament Winder – Compact Multi-Axis Filament Winding Machine for Pressure Vessels, COPVs, and Small-Scale Production

The SC+ filament winder from Engineering Technology Corporation (ETC) is a compact, multi-axis filament winding machine with an adjustable tailstock designed for small pressure vessels and other geometries that require additional axes of motion, enabling precise fiber placement on bottles, domes, tapered structures, and other complex rotationally symmetric composite parts while supporting advanced composite development, prototyping, and small-scale production.

Bridging the gap between laboratory winding and manufacturing, the SC+ filament winder combines advanced winding capability with a space-efficient design, making it ideal for organizations transitioning from process development to production.

Equipped with ETC’s FWC11 control system and optionally with FiberGrafiX^® winding software, the SC+ provides an intuitive user experience that simplifies machine operation and process monitoring. The modern Windows 11-based platform helps reduce setup time, accelerate operator training, and deliver consistent, repeatable results from prototype development through low-volume production.

The SC+ filament winder is part of ETC’s standardized filament winding portfolio – engineered to deliver reliable performance, optimized pricing, and reduced lead times. Its compact multi-axis design provides an ideal solution for pressure vessel development, advanced composite prototyping, process validation, and small-scale production.
