Continuous PU Sandwich Panel Line Continuous PU Sandwich Panel Line

Continuous PU Sandwich Panel Line

Product Description

Continuous Polyurethane Sandwich Panel Line is the automation equipment that can continuously and efficiently produce polyurethane sandwich panels of exquisite and diverse shapes.

 This Sandwich panel line has the advantages such as high durability, easy management, technology equivalent to those of advanced European companies and relatively competitive price, and it is the excellent facility.

Continuous PU Sandwich Panel Line consists of Un-coiler that inputs and releases coil, Roll Forming Unit that makes shape of coil, PU Forming Unit that sprays PU solution, Laminating Unit that makes the shape of sandwich panel, Panel Cutting Unit that cuts the fabricated sandwich panel, Cooling Conveyor Unit that finishes products hardening the cut panel sufficiently at intervals, Auto Stacking Unit that loads the finished panels, and Panel Packing Unit that packs the loaded panels with plastic wrap and discharge them.
