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.
