Tires are an important component of transportation such as cars, motorcycles, and bicycles, and play a crucial role in ensuring driving safety and improving driving efficiency. With the continuous development of the field of chemical raw materials, the manufacturing methods of tires have also been continuously improved and optimized. This article will introduce a manufacturing method for tires aimed at improving their performance and quality

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, improve its physical properties and chemical stability

4. Promoter: used to accelerate the vulcanization process

5. Antioxidant: Used to prevent rubber aging

3、 Mixing process 

1 Add raw materials such as rubber, carbon black, vulcanizing agent, accelerator, and anti-aging agent to the mixer in a certain proportion

2. Mix the raw materials thoroughly and evenly at a certain temperature and pressure

3. After mixing is completed, release the rubber material for cooling and slicing

4、 Tread pressing 

1 Place the sliced rubber material in the tread mold

2. Under a certain temperature and pressure, press to tightly adhere the rubber material to the mold, forming a tread shape

After pressing, remove the tread from the mold for cooling and trimming

5、 Fetal body shaping 

1 Use steel wire or fiber materials to make the fetal skeleton

2. Apply a layer of adhesive on the fetal skeleton to form the fetal body

3. Stick the tire tread on the tire body to form a complete tire shape

6、 Sulfurization process 

1 Put the formed tire into the vulcanization machine

2. Under certain temperature and pressure, vulcanization occurs to cause cross-linking reactions of rubber molecules, forming a three-dimensional network structure, and improving the physical properties and chemical stability of tires

After vulcanization is completed, remove the tire from the vulcanization machine for cooling and inspection

7、 Quality inspection and testing 

Conduct quality inspection and testing on manufactured tires, including visual inspection, dimensional measurement, physical performance testing, etc., to ensure that the tires meet relevant standards and requirements. For unqualified tires, they need to be reworked or scrapped

8、 Summary and Outlook: This article introduces a manufacturing method for tires, including material preparation, mixing process, tread pressing, tire body forming, vulcanization process, and quality inspection and testing. By optimizing manufacturing processes and selecting high-quality raw materials, tires with excellent performance and stable quality can be manufactured, providing assurance for the safety and efficiency of transportation vehicles. With the continuous progress of technology and the increasing environmental requirements, the manufacturing of tires in the future will pay more attention to environmental protection, energy conservation, and sustainability, explore new manufacturing processes and materials, and improve the performance and environmental friendliness of tires.
