Tire production process

To better understand the tire production process is to get to know the types of tires first

Tire Bias

In these types of tires, in the process of producing tire, the layer yarn is diagonal with the central line of the tire and the layers are crushed. Are not used.

Radial tire

In the rowal tires, which are also found to be in the process of producing the tire, the layer yarn with the center line of the tire is 90 degrees, in other words, the yarns are in the radial direction. The material and materials used in the yarns are usually made of polyester or ray.

The tires are used to stabilize the belt or bolt in the direction of the ivory width and the diagonal angle of the tire. The waist is made of yarn or steel wire. If the belt is cotton, the tire is called the cotton cotton and if it is wire, the tire is called the wired tire. Radial tires have been considered in recent years due to their special benefits to bias tires. However, the process of radial tire production differs from that of each other based on the type of classification (light and heavy burden) as well as the type of technology used (bias and radial). But in general, the tire production process can be summarized in four stages that can be seen in the figure below.

first stage
The process of mixing materials and preparing rubber compounds (compound)

In this part of the tire production process, the raw materials are mixed with the mixer of the mixer (Banburi) and a variety of rubber compounds such as sausage (natural and artificial) soot, oils and chemicals are obtained. From rubber compounds in parts. Different tires are used. Since each tire has different physical and mechanical dictionaries, it is necessary to make different ingredients from rubber materials.

Bennaburi

The internal mixing machine is in the tire production process consisting of three parts.

The mixing part

This part of the tire production process consists of two interrelated two -cylinder, which is made up of two coil spirals called the rotor. Each other is rotating. The rotors work with high voltage engines.

Engine

To mix materials in the process of production of tire inside the mixing chamber, a motor is that the rotor rotates.

Mets

Metwork is a step of the tire production process in which it is used by obtaining the best formulation to combine multiple types of different materials with the selected tire. In the process of producing tires to achieve parameters such as custom properties, better and easier vulcates, more appropriate forming and reaching reasonable price, these materials are mixed with rubber and rubber mixed with the process. So it should be said that the responsibility of mixing work has an important task. In the industry, most commonly in the process of tire production, masticating, combining and mixing of raw materials in the tire using rollers or internal mixer, which is the most widely used Banbury Mixer. Becomes.

second stage
The process of construction and preparation of tire components

The construction and preparation of the constituents is done in the process of tire production in different parts:

Sample

Crispered, walls, rubber strips, shoulders and hamp are among the first parts of the tire production process.

The Clays section

The manufacture of layers (major component of the body or tire) is in the process of producing the tire of the fabric client or yarn fibers or wires covered by this tire. Clazer is used to produce steps or squeezing, foaming or coating operations and covering the most useful.

Crystal sector

The construction of a wireless bolt is done on the stylistic machine and the willow or crown is made in the process of producing the tire in the Bidstestasi sector.

third level

Unlike light tires such as Bias, where the tire production process is one -stage, wired radial tires are usually done in two stages. In the first phase of the process of production of tire tires, including layers, willow and walls are prepared, and the second wireless and crisp beams are added. In a number of tire factories and in heavy tires, they put a number of layers on the machine and transfer them to the tire machine after the straps are prepared. With the assembly of the straps, it is produced and adding a crunchy and crunchy to heavy tire tire machinery.

Tire baking process

The last stage of the tire production process in which the tire is final and its mechanical -dynamic properties are called the cooking or vulcanization stage. Therefore, at this stage the tire is used using the baking agents that are added when mixing the rubber compounds after the baking press is final, and with the heat of the mold, followed by transverse connections in the rubber, elastic and elastic properties. Or find elastic. Unlike most of the chemical industry’s manufacturing processes, the tire production process is a so -called or so -called module process. This process of semi -made materials is made in non -continuous modules. Then combine to provide food to the next continuous and continuous processes. From this point on, the semi -made materials re -converted into separate and separate sections that turn into a tire through a series of tires and baking processes.
