Fiberglass Prepreg Lines
Vertical Glass Fiber Cloth Impregnation Line
NTRY is a system supplier for dipping and coating lines in China. The prepreg impregnation line and glass fiber cloth impregnation and drying production line we produce are mainly vertical impregnation lines, which are currently widely used in the production of glass fiber cloth-based copper-clad laminates (FR-4, etc.). These types of impregnation and drying production lines can continuously and with high precision impregnate, dry, and wind up electronic-grade glass fiber cloth. The equipment is mainly composed of: an automatic impregnation system, a drying tunnel heating and curing system, a hanging conveyor system, and a centralized control system.
