Jinxiang discontinuous polyurethane sandwich panel equipment is used to produce sandwich panels with color steel plates or galvanized sheets (PPGI) on both sides and polyurethane (PU) or polyisocyanate (PIR) insulation materials as the core. Applied to: insulated wall panels and roof panels, garage doors, entrance doors, and cold storage. The discontinuous PU/PIR sandwich panel machine consists of a multi-layer workbench and a guide rail frame. In the actual production process, after the sheet metal is formed, the top and bottom metal plates will be installed on the workbench of the main press machine and sealed with a mold frame. The workbench will bring them into the main press and inject mixed PU or PIR raw materials. At the same time, the material begins to foam and solidify. Time has come, the workbench is moved out, the mold frame is moved out, and the finished sandwich panel is taken out. Then the machine is ready for the next production cycle.
