Metal bending protective film

Bending protective film is mainly used in precision stainless steel bending, stainless steel kitchen utensils and bending, aluminum alloy bend, the emu stainless steel bending, aircraft aluminum alloy parts bending such as requiring higher surface quality. Can also be used for the production of various chassis shell bending stamping on the surface of the product protection. Material: OPP/PE, and other optional. Bending membrane action principle: bending film is between the workpiece and the die corner buffer effect, so as to prevent the workpiece when bending the influence of dust and debris generated indentation, when used as long as the bending membrane on the lower die.
