Fiberglass Prepreg Lines
Vertical Glassfiber 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.

NTRY Vertical Glass Fiber Fabric Impregnation Line
The vertical glass fiber fabric impregnation line provides continuous, high-precision automation for electronic-grade glass fiber fabrics, covering impregnation, drying, and cutting or rolling. Its vertical design allows resin to flow naturally by gravity, reducing pump system complexity, improving resin penetration, and ensuring uniform temperature control. This maintains optimal resin viscosity and enhances product quality and consistency. The impregnated fabrics are widely used for phase insulation, winding, and layer insulation in electrical engineering, motors, and transformers. With insulation ratings up to H 180°C, they are suitable for high-temperature and demanding applications.
