The tyre is a tough, elastic rubber casing connected to the rim of the wheel. Tyres offer an alluring surface for grip and traction and assist as a pillow for the wheels of the moving vehicle. You will find tyres on all automobiles, cars, cycles, trucks, buses, tractors and aircraft. They are also present on industrial vehicles and farm tools like forklifts, and popular conveyances like baby carriages, wheelchairs, carts and motorcycles. For most automobiles, tyres are pneumatic, the air inside the tyre is held under pressure. Before, there was an inner tube present in the pneumatic tyres to keep the air pressure, but now pneumatic tyres are designed differently, now their purpose is to build a pressure seal with the rim of the wheel.
There are mainly two types of rubber that are used, natural and synthetic. Primarily, Natural rubber is used for the manufacturing of tyres, but synthetic rubber may also be used sometimes. The rubber used in Bridgestone Tyres West Bromwich is not just a simple plain rubber, it is a mixture of a variety of chemicals. To acquire properties like strength, wear resistance and resiliency, chemically formulated rubber is needed in the tyres, and then they are heated. Today the production of tyres has increased, approximately 250 million tyres are produced in a year.
TYRE MANUFACTURING PROCESS: EXPLAINED
The tyre of a passenger car is built by rolling numerous coatings of specifically designed rubber around a metal drum in a tyre constructing machine. The several segments of tyres are carried to the constructing machine, where the skilled assembler slashes and places the strips to create the different components of the tyre, at this position it is called a “green tyre”.
- The first and foremost step in the manufacturing of tyres is the blending of raw materials to construct the rubber compound. With the help of railroad cars, a large quantity of natural and synthetic rubber, sulphur, oils, carbon black and other chemicals are delivered and stored until needed. To estimate a certain batch of rubber and chemicals for blending, there are computer control systems that contain several formulae which helps them to automatically measure them. The vertical cement mixers, gigantic mixers, swirl the chemicals and rubber together in bunches.
- Now, the second step is heating, every mix is then milled again with extra heating to smoothen the batch and blend the chemicals. After that, the batch goes again to a mixer, where more chemicals are put in to forge the final mix. Friction and heat are pertained to the batch to smoothen the rubber and distribute the chemicals evenly during all three steps of mixing.
- Body, beads and tread – A batch goes through a strong rolling mill that shoves it into thick sheets, once the rubber has been mixed. These thick sheets that have been shoved, are used to make the specific part of the tyres. For example, the tyre body comprises strips of cloth type material that are wrapped with rubber. Individually, every strip of cloth is used to create a layer known as a ply in the tyre body. A passenger vehicle tyre may have four plies in the body. Now comes the beads, wire stacks are formed on a wire wrapping device, for the beads of the tyre. The stacks present are then converted into rings, furthermore, the rings are covered with rubber. The rubber of the sidewalls and tyre tread trips from the batch mixer to the processing engine known as an extruder. The batch is further mixed and heated in the extruder and is further pushed out through a die to build a coating of rubber and a protective plastic sheet is used to cover and roll the sidewall rubber.
The manufacturing of rubber is not an easy, small process. Whether they are expensive tyres or Cheap Tyres West Bromwich, the formation of all of them are typical and require a lot of time and patience.
