Sandwich Panel Line

Brief Introduction
Sandwich panel line is a type of integrated production line which includes a roll forming machine and a sandwich panel lamination system. Three types of panels, namely flat wall sandwich panel, push-in sandwich panel and corrugated sandwich panel are manufactured by this production line.

Workflow
Step-1 Roll Forming System
Loading of steel coil (put the steel coil into the decoiler)→Sheet guiding (steel sheet is guided into the first roller through the guiding equipment) → Pre-shearing →Roll forming of panels → Supporting table

Step-2 Sandwich Panel Laminating System
