　　Due to different applications, the models are divided into: solvent-free special type, solvent-free and dry compound combination type, and multi-functional combination type.

　　Special: it can only be used for solvent-free composite, with two-layer structure and three-layer structure for one-time molding; It is also divided into manual roll change and automatic roll change.
