Discontinuous PU Sandwich Panel Production Line for 6m 12m length and 2+2 Press machine
Description
1. Discontinuous PU Sandwich Panel Line is to produce the sandwich panel with the color steel or galvanized sheet(PPGI) on upper and lower sides and the core of polyurethane(PU) or Polyisocyanurate Foam (PIR) insulated material.
2. The main press machine is consisted of the multi-layers of working tables and the rail stands. During actual production, after roll forming the sheets profile, the top and bottom metal sheets will be installed on the working tables of the main press machine, seal with mould frames. Working tables will take them and move into the main press machine. Injecting mixed PU or PIR raw material. Meanwhile the material start foaming and curing. When the time is up, working table moves out, moulds frames are moved out for taking out the finished sandwich panels. Then the machine is ready for next production cycle.
3. The main press machine produces PU or PIR sandwich panel for Max. Panel Length 6m, 8m, 9m, 10m, 12m, 16m…
Adjustable Panel Width less than 1.2m,
Different Thickness 30-200mm.
