The manufacturing method of insole and its finished product.

Technical field：
The present invention relates to shoe materials, in particular to a method for manufacturing an insole with a granular surface.

Background technique：
The general insole is to allow the user to have a more comfortable stepping on the foot when walking with shoes. In order to make the insole more elastic and breathable, it is usually formed on the top surface of the insole with a number of granular protrusions. When the user steps on the top surface of the insole, the contact surface between the insole and the sole of the insole is concave and convex, which increases the insole's Elasticity and breathability. Usually insoles with a granular top surface are made of high molecular compound materials (such as foam or rubber) through mold forming. Because the inner surface of the mold has several dimples, the top surface of the insole after processing is integrally formed Several grainy protrusions.
However, in the above-mentioned insole structure made by integral molding, the bottom surface of the insole is easily affected by the shape of the protrusions protruding from the top surface, so that the position of the bottom surface relative to the protrusions is concave, and the insole passes through After continuous and repeated use, the convex parts formed by the mold are easily deformed downward due to the downward pressure of the foot, so as to disappear, making it difficult for the insole to maintain stable elasticity and air permeability under long-term use.

Summary of the invention
The main purpose of the present invention is to provide a method for manufacturing an insole, and an insole made by the method, so that the insole can still have stable elasticity and air permeability under long-term use.
In order to achieve the above-mentioned object, the method for manufacturing the insole used in the present invention includes the following steps: a. Prepare a sheet-like substrate with a large number of perforations penetrating through the top and bottom sides; the material of the substrate is high Molecular compound; b. Immerse the base material in a filling material with fluidity, so that the filling material is fully injected and fixed in each perforation of the base material; the material of the filling material is a polymer compound and is different from the material of the base material; c. Put the substrate into an oven for baking; d. Cut the substrate into a desired thickness; e. Stick a cloth layer on one side of the substrate; f. Cut the substrate to form a number of insoles; g , Each insole is press-molded separately, so that the top and bottom sides of each insole are compressed, the filler in each perforation protrudes from the two sides, and the surface of the cloth layer forms a number of granular protrusions.

Due to the adoption of the above technical solutions, the present invention has stable elasticity and air permeability, and by combining the materials of the base material and the filling material with different hardness materials, the insole can be applied to various types of shoes. The convex parts of the insole can also be designed in different arrangements to achieve the effect of massaging the feet.
