Flame compounding machine is a rapid flame burning sponge surface, made of polyester, poly-ether, polyethylene sponge or other viscous film, fabric, PVC film, artificial leather, non-woven and other thermoplastic materials and other materials synthesis. Three layers of material can be combined simultaneously through two sets of combustion furnaces. The bonding principle is that the sponge is quickly melted by using a linear gas burner. The sponge produces a sticky film. The sponge, the upper fabric and the lining are bonded together through the bonding gap. Featured by good integration and hand touch, water-washing and dry-washing serviceability. It is especially fit for the compound of plush and abrasive brush.
