Description

Two-time integrated shoe and shoe-making mold and manufacturing method

technical field

The invention relates to a secondary integrally formed shoe, a shoe-making mold and a manufacturing method.

Background technique

Shoes generally have a sole and a vamp, and are a kind of footwear for protection and decoration. The sole part and the upper part are generally made of different materials, and then combined by machine stitching, glue bonding, injection molding or molding vulcanization. This manufacturing method requires more processes, consumes manpower and material resources, and produces more environmental pollutants. There are more materials in the production process that cannot be reused, resulting in waste of resources. And the shoes that this connection method makes, sole and vamp are easy to break away from, or seep water.
