PIR Sandwich Panel Machine, also called polyurethane sandwich panel manufacturing line/production line/machine, is an automatic production line, which is consisting of decoiler, film coating, pre-cutting, cutting equipment, roll forming system, preheating, foaming, solidification, band saw cutting, cooling, stacking and packing. The PIR Sandwich Panel Machine is welded by strong steel plates which ensure high strength.Machine frame adopts heat – treatment which help release the welding stress and ensure machine non – deformation.
The steel plates of Double – belt system adopt multiple time heat treatment with stress relief annealing techinque, then multiple – time rough machining and grinding process by Numerical vertical machining centre, to guarantee the surface with high flatness. Thus it will achieve perfect flatness of the final sandwich panel.
