1. Introduction: Leather processing is the processing of real leather, PU and artificial leather, also known as leather processing.

Two, equipment: beer machine, shoveling machine, sewing machine, computer sewing machine, embossing machine, gluing machine, punching machine, sanding machine, splitting machine, nailing machine, cloth ironing machine Machine, straightening machine, tooth extraction machine, folding machine, etc.
