Fiberglass Prepreg Lines
Vertical Pre-Preg Impregnation Line For Glass Fiber Epoxy
The vertical prepreg impregnation production line is suitable for continuous impregnation, drying, winding or cutting of 7628, 2116, 1080 and other electronic-grade glass fiber cloth, felt, and paper. It adopts imported far-infrared heating panels with thermal-oil radiant heating and hot air drying, and multi-point temperature control on the left, middle and right sides. The prepreg surface is smooth, free of impurities and bubbles. The finishing adopts closed-loop servo control, multi-point tension control, and constant tension throughout the line.
