JWELL Slot-die Extrusion Coating Unit
JWELL slot-die extrusion coating unit uses an enclosed quantitative adhesive supply system for high cross-web uniformity. It combines precision micro-adjustment, a quick die head in/out mechanism and a high-precision coating backing roller for stable wet-film transfer across wide webs.
Key Selling Points
- Enclosed Quantitative Supply: Enclosed quantitative adhesive supply system, ensuring coating uniformity within ±1.5 μm across a 1000 mm width.
- Precision Micro-Adjustment: Equipped with a precision micro-adjustment mechanism with an adjustment accuracy of 0.001 mm.
- Quick Die In/Out: Integrated quick die head in/out mechanism, with a repositioning accuracy of ≤ 0.005 mm.
- High-Precision Backing Roller: The coating backing roller meets high-precision requirements, with all tolerances within ≤ 0.002 mm.
Technical Specifications
Main technical parameters
