The inner and outer layer of PVC co-extruded foaming board is hard PVC, and the core layer is PVC foaming layer, which can greatly reduce the equipment cost and formula cost (compared with the real skin foaming equipment). The product quality and all aspects of parameters are close to or better than the real skin foaming board (1.22m product width, 5~20mm thick, density ~0.5g/cm3, surface strength: 50~75 Rockwell hardness), and the surface of the products can be hot stamping, printing or film, to obtain different patterns and patterns, in addition to some need to fold the application occasions, after hot bending treatment can meet the application requirements.

Equipment composition: it is composed of extruder, distributor, mold, shaping template, cooling frame, tractor, cutting machine and stacking table, with high precision and easy operation.
