Uses: mainly used for uppers of sandwich mesh, leather, material such as microfibre seamless fit, direct hot forming, replacing sewing machine sewing. Usage: used generally by hot laminating machine laminating adhesive layer to leather, on base material such as microfibre, high frequency with the substrate after fusing machines-blast cut, again through high frequency heating equipment such as machines, pressing machines, with the plastic film substrate bonded to the upper body (this step can be performed concurrently with the high frequency embossing).
