COMPOSITES TUFTING HEAD

eCTH (Composites Tufting Head) is specially designed for the production of sub-preforms and preforms.

It is a unique device for high-speed tufting on carbon or glass composites typically used in the field of aerospace, automotive, wind energy, or industrial lightweight construction.

High Speed Tufting

This high-speed tufting head is working with one needle and a single thread. It is inserting a thread through layered composite fabrics, using a single needle that, after insertion, moves back along the same trajectory leaving a loop of the thread inside or outside of the structure, whether it is a glass or carbon fibers composites.

It resembles stitching, but it is different. eCTH tufting head only requires access from one side of the preform.

Uniform Tufting

Thanks to the unique tufting technique, it forms very uniform and even loops. All tufting parameters (stitch rate, stitch length and profile of needle movement) are electronically adjustable and there is no need for any mechanical adjustments.
