Benefits of technology

This new technology allows for easier application of an elastic material onto shoes without causing damage or discomfort during wearing them over time. By applying a special chemical called Polyurea® (PUR) instead of PU foam inside the bottom part of each shoe's midsole, it becomes smoother and more stable at wearer comfort compared to traditional methods that require rubbing agents between layers before injection into the final product. Additionally, there are also added features like air holes underneath the outsole lining which further enhances its effectiveness against vibrations caused by changes in point locations. Overall, these technical improvements improve durability and reduce strain on feet while still providing effective shock absorption properties.

Problems solved by technology

This patented describes how we can make shoes with good ventilation for feet while also having strong connections between them without making their movement difficult or disrupting us' movements during use.

Abstract

A manufacturing method of an insole is characterized in that: the method comprising the following steps: selecting and preparing raw material, spraying a parting agent on the inner surface of an upper die body (21), padding insole surface cloth (12) on the inner surface of a lower die body (22), then closing a die (2), vacuumizing the die through an extractor vent (23) to cause the insole surface cloth (12) to be smoothly and firmly attached to the inner surface of the lower die body (22); blending a component a and a component b, injecting the mixture into the die (2) from a die sprue (24) and staying for 2-30 minutes; taking out the insole (1) with rough edges which combines the insole surface cloth (12) and polyurethane; deburring to obtain the finished product. The manufacturing method of the invention has the advantages that: the polyurethane surface at the reverse side of the insole is a non-membrane surface, when in use, the insole can be attached to the sole surface, thus solving the problem of easy sliding of the insole due to the change of an exerting point of the sole when people walk. In addition, when people stamp on the insole, a soft cushion structure of the insole produced by the method can lead to better shakeproof effect, causes people to feel soft and comfortable, and has the advantages of good intensity and convenient manufacturing.
