One-piece formed sole processing process

Abstract

The invention relates to a one-piece formed sole processing process, in particular to a processing process for forming sole sand insoles. The processing process comprises: performing a manufacturing process of wear-resistance rubber material soles; performing a manufacturing process of elastic ethylene vinyl acetate (EVA) insoles; mixing the EVA material and rubber material in a certain ratio, wherein the content of EVA is 30 to 40 percent; forming shoe-shaped cover pieces; placing the cover pieces on the soles; placing the insoles made by the EVA manufacturing process on the cover pieces; and performing thermocompression of the soles and the insoles by heating a template and applying die compression, wherein the heating temperature is 150 to 165 DEG C, and the applied die pressure is 70 to 80KG / CM2. Because the cover pieces made of the mixed material, after undergoing thermocompression with the soles and insoles, have a very big adhering force, the soles and the insoles are combined, the separating phenomenon is eliminated, lots of labor cost can be saved in a production process, the dangers caused by the conventional production process to the health of human body are eliminated, and the production environment of the plant is improved.

Description

technical field [0001] The invention relates to the technical field of shoe sole production technology, in particular to a processing technology for outsole and midsole molding. Background technique [0002] In order to increase the wear resistance of shoes, the outsole of shoes is generally made of rubber material. In order to increase the comfort and elasticity of shoes, the middle and bottom of shoes are generally made of softer EVA material. Difficult. At present, the processing method generally adopts manual methods. First, roughen the bonding surface of the artificial outsole and midsole shoe materials, and then apply a treatment agent on the bonding surface of the sole, and glue them together. The entire production process requires A large number of manual operations have low production efficiency and high labor costs, and in the process of bonding and gluing, the glue will emit a pungent smell, which will pose a greater threat to human health. And this adopts artifi...

[0002] In order to increase the wear resistance of shoes, the outsole of shoes is generally made of rubber material. In order to increase the comfort and elasticity of shoes, the middle and bottom of shoes are generally made of softer EVA material. Difficult. At present, the processing method generally adopts manual methods. First, roughen the bonding surface of the artificial outsole and midsole shoe materials, and then apply a treatment agent on the bonding surface of the sole, and glue them together. The entire production process requires A large number of manual operations, low production efficiency, high labor costs, and in the process of gluing and gluing, the glue will emit a pungent smell, which will pose a greater threat to human health

And this kind of artificial gluing method is not firm enough, and it is easy to cause degumming.
