JWELL Single / Double-sided Diaphragm Coating Equipment
JWELL's water-based diaphragm coating equipment applies mixed slurry evenly onto the substrate for battery separator film layers. The line combines an unwinding unit, preheating unit, haul-off coating unit, electrically heated hot-air oven, shaping and cooling unit, winding unit and electronic control system, and is offered in vertical and horizontal layouts.
Key Selling Points
- Uniform Coating: Applies mixed slurry evenly so size and weight stay within the design specification for battery isolation film layers.
- Integrated Drive and Tension: Optical, mechanical and electrical systems are designed together for stable running tension and neat winding.
- Vertical or Horizontal: Water-based diaphragm coating machines are available in vertical and horizontal models.
- High Operating Speed: Operating speed up to 200 m/min with continuous transfer kiss coating or spraying.
- Non-stop Splicing: Unwind and rewind support non-stop automatic splicing at Φ500 mm roll diameter.
