Method for fabricating customized insole

Abstract

A method for fabricating a customized insole comprises the following steps of: firstly, wrapping the foot of a person subject with cotton cloth dipped with gypsum water to form a surrounding container, and taking off the cotton cloth after being dry and hard; secondly, pouring gypsum water into the dry container and then taking out the gypsum model after dryness, so as to obtain a male mold of the foot bottom; smoothly polishing the male mold and heightening at the foot arch part for fabricating a foot bottom model; next, buckling the male mold of the foot bottom with the heightened foot arch part on a base plate in an airtight space in a back off manner; putting an EVA sheet larger than the profile of the insole in pure size by 5mm in an oven for heating, and then putting the EVA sheet on the male mold of the foot bottom with the heightened foot arch part; vacuumizing the airtight space and molding the EVA sheet into the insole fitted with the foot bottom in shape; and finally, taking the molded EVA sheet out of the airtight space, and performing cutting, burr grinding and polishing treatment according to the shape of the foot bottom, so as to obtain the customized insole completely united with the foot shape. The method provided by the invention is low in cost, high in fabrication speed, and simultaneously, capable of guaranteeing the customization effect for different people and different foot shapes.

Description

technical field [0001] The invention relates to a method for manufacturing an insole, in particular to a method for manufacturing a customized insole. Background technique [0002] The most common insoles currently on the market are ordinary flat insoles. This kind of insole has simple manufacturing process and low cost, but because it does not meet the anatomical structure and sports biomechanical requirements of the human foot, the comfort of the feet is poor for long-term wearing, and may Cause foot diseases such as arch collapse, forefoot pain, calcaneal pain, etc. [0003] In addition, many sports shoes use three-dimensional insoles, and their shape and structure can basically meet the requirements of foot shapes. However, due to mass production, individual differences in human feet are ignored. In some professional customized insole mechanisms, each pair The production of insoles requires separate molds, so the cost is high and the time is long. Contents of the inve...
