PVC Foam Board Machine For Furniture , WPC PVC Foam Board Making Machine Extrusion Line

Quick detail:

1.Rigid PVC foam products are foamed and molded with chemical foaming agents. The blowing agent and its decomposition gas are dissolved in the melt before entering extrusion die, then after passing the extrusion die, the pressure and temperature in the melt decreases, so that the gas dissolved in the melt is supersaturated and phase separation occurs to form plenty of microbubbles. The surface bubbles are fixed before they expand on the board surface due to the rapid cooling of the cooling setting mold, then a dense and smooth crust layer formed on the surface, thereby producing a crust foam board.
2.The rigid PVC crust foam board adopts a restricted foaming process. The melt is freely foamed from the clothes-hanger die, and then introduced into a cooling station with a size similar to the die, immediately forced cooling on the surface of the board to suppress the surface area of the board foaming (crust) to obtain a foamed semi-finished product with a relatively hard surface. After passing through the cooling zone, it is drawn by the traction device into the pressing roller device. In order to compensate for the subsequent cooling shrinkage of the sheet, the size of the cooling setting device is about 1% larger than the thickness of the sheet. The cooling intensity of the cooling setting die is different, and the thickness of the sheet skin is controlled to vary between 0.1 mm and 1.0 mm.

Description of pvc board equipment:

1.pvc foam board extrusion machine is composed of Conical twin screw extruder, board mould, sizing table, cooling bracket, traction machine, cutting machine and other auxiliary machine.

2.Extruder is adopting special designed screw, the production line adopt import famous electrical parts, such as siemens motor, ABB inverter, Schneider and other brand. Our machine has high performance, long service life.

3.PVC foam board have anticorrosive, moistureproof, mouldproof, not bibulous, drilling, sawing, planing, easy to hot forming, hot bending processing features, therefore widely used in furniture, cabinets, bath cabinets and exhibition board, box core layer, indoor and outdoor decoration, building materials, chemical industry and other fields with boards, advertising signs, printing, screen printing, spraying, computer lettering, electronic instrument product packaging and other industries.
