TPU multi-group casting composite material is a kind of material that realizes 3-5 layers of composite of different materials through multi-group step casting line composite. The surface molding is beautiful, and different patterns can be made. With superior strength, wear resistance, safety and environmental protection performance, it is used in inflatable life jacket, diving BC jacket, life raft, hovercraft, inflatable tent, inflatable water bag, massage air bag, medical protection, industrial conveyor belt and professional waterproof backpack and other special composite products with high strength.

    This production line adopts multiple extruder and multiple sets of unwinding device, step by step casting forming, and realize line one step compound forming, can be equipped with online multi-group thickness measurement control, the production line design of a variety of different composite way combination, a production line can realize a variety of product forms of production technology. For some special fabrics, it can be synchronized with the fabric pretreatment coating production line to meet the production needs of different products.
