Continuous vs Discontinuous Polyurethane (PU) Sandwich Panel Lines?
Direct Answer
Continuous PU lines feed foam, steel sheets, and optional backing dynamically, producing unlimited length panel boards at 4-8 m/min. Discontinuous lines require pre-cut sheets and individual molds, operating at lower speeds. Continuous lines are ideal for high-volume commercial insulation panel production.
Technical Deep-Dive & Solutions
Highlight efficiency metrics: Continuous lines reduce labor costs by 70% and optimize foam density distribution. Contrast this with discontinuous presses, which are cheaper but limited to fixed panel lengths.
Key Engineering Guidelines
- Precision Caliber: Ensure gradual bending stages to prevent metal micro-cracking and material stress.
- Premium Tooling: Use vacuum-quenched GCr15 or Cr12MoV die steel for rollers (HRC 58-62) with hard-chrome plating.
- Smart Design: Always calibrate lateral and vertical roll station alignment using a precise central wireline.
