Automobile tire production process

As an important component of automobiles, the production process of automotive tires involves multiple complex and delicate steps. This article will provide a detailed introduction to the production process of automotive tires, allowing readers to have a deeper understanding of the tire manufacturing process.

1、 Preparation of raw materials

The first step in tire production is to prepare raw materials. This mainly includes various raw materials such as natural rubber, synthetic rubber, carbon black, sulfur, oil, etc. These raw materials need to undergo strict quality inspection to ensure that they meet production requirements.

2、 Mixing

Mixing is the process of evenly mixing rubber with various additives (such as carbon black, sulfur, etc.) in an internal mixer. During this process, factors such as the proportion of raw materials, mixing time, and temperature can all affect the performance of the final rubber. After mixing, the rubber mixture is obtained.

3、 Rolling

Rolling is the process of pressing a rubber mixture into a certain thickness and width of film through a rolling machine. During this process, it is necessary to accurately control the temperature, speed, and pressure of the rolling process to ensure uniform thickness and width of the film.

4、 Forming

Forming is the process of making the film into a tire preform through a molding machine according to the design requirements of the tire. During this process, the film needs to be glued together to form the tire's carcass structure. At the same time, tire beads should also be added to the tire body so that the tire can be fixed on the wheel hub.

5、 Vulcanization

Vulcanization is the process of placing the tire blank into a vulcanization tank and causing a chemical reaction of the rubber mixture under high temperature and pressure to form a cross-linked structure. During this process, it is necessary to accurately control the temperature, time, and pressure of vulcanization. After vulcanization, the shape and structure of the tire are basically determined.

6、 Inspection and Testing

The vulcanized tires need to undergo strict inspection and testing to ensure that their quality meets the standards. This includes visual inspection, dimensional inspection, air tightness testing, wear resistance testing, etc. Only tires that pass all tests will be considered qualified products.

7、 Packaging and Delivery

Finally, qualified tires will be packaged to prevent damage during transportation and storage. After packaging is completed, the tires can be shipped from the factory to various sales points for consumers to choose from.

The production process of automotive tires is a complex and delicate process, involving multiple steps such as raw material preparation, mixing, rolling, forming, vulcanization, inspection and testing, as well as packaging and delivery. Each step requires precise control of various parameters to ensure the quality and performance of the final product. By understanding the production process of tires, we can better understand and appreciate the exquisite craftsmanship and rigorous attitude behind each tire.
