The manufacturing method
of shoe material
1. Introduction

With the progress of science and technology and the improvement of consumer demand, the manufacture of shoe material has gradually become an important part of the field of chemical production raw materials. Manufacturing high quality shoe materials requires precise control and unique technology to meet different performance requirements, such as wear resistance, comfort, breathability, antibacterial and deodorant. This article will introduce the manufacturing method of shoe materials in detail, including raw material selection, mixing, molding, processing and other steps.

2. Raw Material Selection

1. Rubber: Rubber is a commonly used material in shoe material manufacturing, with excellent elasticity, wear resistance and impact resistance. Commonly used types of rubber include natural rubber, synthetic rubber, etc.
2. Plastic: such as polyvinyl chloride (PVC), polyurethane (PU), etc., with light weight, easy processing, wear resistance and other characteristics.
3. Fabric: including cotton, linen, nylon, polyester, etc., used to make uppers and linings to provide comfort and breathability.
4. Accessories: such as plasticizers, fillers, antioxidants, colorants, etc., used to improve the performance and appearance of shoe materials.

3. mixing

mixing is a process in which raw rubber and various compounding agents are mixed together through mechanical equipment to obtain mixed rubber with uniform performance. During the mixing process, attention should be paid to the control of temperature, time, pressure and other parameters to ensure the quality of the compound.

4. molding

molding is a process in which the compound is processed into the required shape and size. The commonly used molding methods are:

1. Calendering molding: The compound is pressed into a certain thickness and shape by a calender The film is used to make soles and uppers.
2. Injection molding: The compound is injected into the mold and shaped by heating and cooling to make soles and heels with complex shapes.

5. processing

processing is to further treat the formed shoe material to improve its performance and appearance, including:

1. Vulcanization: The rubber molecules are crosslinked by heating and pressure to improve the elasticity of the shoe material, Wear resistance and aging resistance.
2. polishing: grinding and polishing the surface of the shoe material to improve its gloss and appearance quality.
3. Printing: Printing patterns and words on the surface of shoe materials to increase their beauty and personalization.

6. quality control

In the manufacturing process of shoe materials, strict quality control is required to ensure product consistency and reliability. This includes quality testing of raw materials, monitoring of the production process, and performance testing of finished products. At the same time, we also need to pay attention to environmental protection and sustainability, choose environmentally friendly materials and processes, and reduce waste and pollution in the production process.

7. Conclusion The manufacturing method of

shoe material involves multiple links and processes, which require precise control and unique technology. Through reasonable raw material selection, mixing, molding and processing, high-performance and high quality shoe materials can be manufactured to meet the needs of consumers. At the same time, quality control and environmental awareness need to be strengthened to improve the efficiency and sustainability of production. With the continuous development of science and technology, the manufacturing methods of shoe materials will continue to improve and innovate, bringing more possibilities and opportunities to the shoe industry.
