Tire manufacturing methods

1. Introduction

tires are an important part of automobiles, motorcycles, bicycles and other vehicles, and play a key role in ensuring driving safety and improving driving efficiency. With the continuous development of raw materials for chemical production, tire manufacturing methods have been continuously improved and optimized. This article will introduce a tire manufacturing method aimed at improving the performance and quality of tires.

2. material preparation

1. Rubber: The main material of tires is rubber, and high-quality natural rubber or synthetic rubber needs to be selected.

2. Carbon black: used to increase the strength and wear resistance of rubber.

3. Vulcanizing agent: used to vulcanize rubber and improve the physical properties and chemical stability of rubber.

4. Accelerator: Used to accelerate the vulcanization process.

5. antioxidant: used to prevent rubber aging.

3. mixing process

1. rubber, carbon black, vulcanizing agent, accelerator and antioxidant and other raw materials in accordance with a certain proportion of the internal mixer.

2. at a certain temperature and pressure, mixing, so that the raw materials are fully mixed.

3. After the mixing is completed, the compound is released, cooled and sliced.

4. Tread Pressing

1. Place the sliced compound in the tread mold.

2. Press at a certain temperature and pressure to make the rubber fit closely on the mold to form a tread shape.

3. After the pressing is completed, the tread is removed from the mold, cooled and trimmed.

5. Carcass Molding

1. Use steel wire or fiber material to make the carcass skeleton.

2. Coat a layer of rubber on the carcass skeleton to form a carcass.

3. Paste the tread on the carcass to form a complete tire shape.

6. vulcanization process

1. Put the molded tire into the vulcanizer.

2. Under a certain temperature and pressure, vulcanization is carried out to crosslink the rubber molecules to form a three-dimensional network structure and improve the physical properties and chemical stability of the tire.

3. After the vulcanization is completed, take the tire out of the vulcanizer, cool it down and check it.

7. quality inspection and testing

quality inspection and testing of manufactured tires, including visual inspection, dimensional measurement, physical performance testing, etc., to ensure that the tires meet relevant standards and requirements. For unqualified tires, rework or scrap is required. Summary and Prospect of

This paper introduces a tire manufacturing method, including material preparation, mixing process, tread pressing, carcass molding, sulfurization process and quality inspection and testing steps. By optimizing the manufacturing process and selecting high-quality raw materials, tires with excellent performance and stable quality can be manufactured to ensure the safety and efficiency of vehicles. With the continuous progress of science and technology and the continuous improvement of environmental protection requirements, the future tire manufacturing will pay more attention to environmental protection, energy saving and sustainability, explore new manufacturing processes and materials, and improve the performance and environmental protection of tires.
