Abstract

Method of manufacture of multi-layer forming plate for front, rear shoesoles, especially when the forming plate for the front, rear shoesoles is made of a variety of materials by extrusion of sound rigidity and wide use, being the manufacture of various layers (3, 5 or 7 in extrusion), mainly consisting of: 2 adhesive external layers and the inward layers of thermal plastic of recyclable materials and the center layer of thermal plastics of sound rigidity as a 7-layer plate; being the 2 external layers of the 7-layer plate of adhesive substance and the 2nd layer from outside thermal plastic and the inward layers convertible into center layers of thermal plastic plus the recyclable materials and the center symmetrical layer of thermal plastic of sound rigidity as another 7-layer plate; further, another 5-layer plate of 2 outer adhesive and the inner corresponding layers of sound rigidity and the center layer thermal plastic plus the recyclable material; further, the 5-layer having the 2 outer layers adhered to the adhesive and the center layer of thermal plastic of sound rigidity and the 2 outward layers from the center of thermal plastic of recyclable material; being the method of manufacture having the different materials properly stirred at a preset rate before being led into the inlet of the extruder before properly blended and extruded to form a rigid structure of proper crack resistance.
