3. Precision Glue Application: ±5% flow accuracy, 500-4000g/min coating amount, width up to 3000mm.

4. Large Format Capability: Handles panels up to 3m wide, 13m long, and 100mm thick.

5. High Output: Production line speed up to 6m/min, ideal for RV and refrigerated truck panel manufacturing.

Description:
The LY-15-3000 Multilayer Vacuum Hot Pressing Production Line is a comprehensive, fully integrated solution engineered for high-volume manufacturing of large-format composite panels used in the transportation industry, specifically for RV cabins and refrigerated truck bodies. This 73-meter long line (customizable) seamlessly integrates multiple critical processes: unwinding of facing materials, precision CNC glue spraying, automated layup, 4-layer negative pressure machine, and final cutting. The core of the line is the 4-layer negative pressure machine, which applies uniform vacuum pressure simultaneously to multiple panels, dramatically increasing throughput while saving floor space. The CNC glue spraying system ensures accurate adhesive application (≤±5%) across widths up to 3000mm, compatible with both single and two-component adhesives. With the ability to process panels up to 13 meters in length and 100mm in thickness, this production line delivers consistent, high-strength, bubble-free composite panels, making it the ultimate turnkey solution for large-scale panel manufacturers.

Specifications

Applications:
