The Making Of Tyres: Tyre Parts & Manufacturing Process

When creating a tyre, Goodyear tyre producers keep their high-quality standards in mind. They must guarantee that the finished product is safe, provides stability and balance, has outstanding traction, is eco-friendly, and is long-lasting. Most significantly, they should be affordable. A tyre is a complicated mix of elements constructed from a variety of materials. Natural rubber is the primary raw material used in tyre production, while synthetic rubber is sometimes utilised. Nevertheless, to produce the necessary properties of strength, resilience, and wear endurance, the rubber must be processed with some agents and then heated.

Once we’re in the specifics of the Goodyear Tyre production process, it’s important to understand some common tyre terminology. Here’s a simple tyre dictionary to help you understand the many parts of a tyre –

PLY

The core of the tyre is made up of plies, which are layers of cloth. Plies diminish elasticity while maintaining tyre flexibility. They are typically constructed from rubber-coated cables created by woven threads. Your tyre is strengthened by a layer known as a carcass ply, which is placed right over the tyre’s inner lining.

BELT

Rubber-coated woven sheets of a steel cable are wrapped around the tyre. These belts provide stiffness and increase the durability of the tyres. Some tyre versions feature Kevlar cord for increased durability and puncture prevention.

SIDEWALL

The exterior of the sidewall contains information from the manufacturer regarding your tyre. From the bead to the sole, the sidewall is continuous. This extra-thick rubber region offers lateral stiffness.

SIPE & GROOVE

The deep grooves that divide the tread blocks of your tyre dissipate water. Sipes are the tiny grooves in the tread blocks that are crucial for holding ice and snow in the cold.

TREAD

The tread is where all the rubber touches the road, providing traction as well as cushioning. Many of the tyre’s most essential characteristics are determined by the rubber composition and tread pattern.

SHOULDER

A tyre’s small tilt edge in which the tread and sidewall touch. The design and implementation of the shoulder are critical in delivering proper corner effectiveness.

BEAD

A bead is a ring-shaped steel cable with a rubber covering that is comprised of numerous ring-shaped steel wires. It acts as an unbroken seal between both the rim and the tyre.

THE MANUFACTURING PROCESS

Tyre manufacturing is a multi-step procedure. Let’s take a look at a Continental tyre as it goes across all five phases of tyre production.

BLENDING OF RAW MATERIALS

The production of tyres begins with mixing. Your tyre’s rubber contains up to 30 different types of rubber, additives, and other chemicals. The chemicals are combined in massive blenders to form a black, sticky product that will be milled. Rubber is the most common raw material used in tyre production, and both organic and inorganic rubber is employed. To make raw rubber for tyre production, liquid latex is combined with chemicals that cause the rubber to harden. To make raw rubber for tyre production, liquid latex is combined with acids that cause the rubber to harden.

Carbon black is another important component of tyre rubber. Tires also contain sulphur and other compounds. Various tyre properties are produced when particular chemicals are combined with rubber and thereafter heated.

MILLING & STRUCTURING

When the rubber has cooled, it is sliced into strips that will comprise the fundamental framework of the tyre. Other tyre elements are created during the milling stage, many of which are then covered in a different type of rubber. Pre-treated steel rope on wire spindles is inserted into a calendar and embedded in one or more sheets of rubber. As a consequence, a continuous sheet of string and rubber is formed. The kneadable rubber substance, which has been mixed in a mixer, is now ready to be formed into the tread. The rubber is formed into an infinite strip of tread using a screw-type extrusion. A massive roller mechanism feeds a slew of textile strands into the calendar, which is then embedded in a light coating of rubber. The bead’s core is composed of several ring-shaped steel wires. They each have their unique rubber covering.

BUILDING OF TYRE

The tyre is formed from the inside out throughout the construction process. A tyre making machine has a variety of components such as steel belts, textile parts, ply, beads, and tread. The tyre looks to develop the correct shape during this phase and is referred to as a ‘green tyre.’ This is accomplished in two stages: casing and tread assembly. The tyre assembler begins by tying the body’s rubber-covered textile plies all-around mechanical drum. The beads are inserted and fastened into place with extra tyre body plies put over the beads after the edges of these plies are bonded with glue. The assembler then shapes the edges of the tyre plies with unique power tools.

CURING OR VULCANISATION

The green tyre is next vulcanised in a curing process using heated moulds, squeezing all of the tyre’s pieces together and providing the tyre with its final form, such as the tread pattern and company’s sidewall marks. As the clamshell mould closes, the bladder fills with steam and contracts to form the tyre and drive the blank treads rubber against the elevated inside of the mould. The steam warms the green tyre to 280 degrees during the curing process. The time spent in the mould is determined by the tire’s intended properties. Each tyre is rigorously examined for faults such as bubbling or holes in the tread and sidewall rubber.

INSPECTION OF QUALITY CONTROL

Trained experts will now meticulously scrutinise each tyre for the tiniest defect or flaw before it is dispatched for sale. In addition, a sample of tyres is selected from the machine for x-rays to look for probable internal flaws or failures. In addition, our quality control engineers arbitrarily choose tyres from the production line and cut them open to check they fulfil criteria. Plant managers may trace samples of rubber and individual tyre components using code numbers and a thorough computer record system. Hundreds of tyres are pulled from the ends of the manufacturing line for destructive testing when a new tyre design is made for the first time. X-ray videography gives a rapid and informative look inside a tyre. An X-ray tyre test involves selecting a tyre at random and transporting it to a radiation chamber where it is hit with X-rays.

CONCLUSION

The quality team guarantees that only high-quality tyres leave their production plants. As a result, the complete product line corresponds to the company’s criteria. That’s all there is to it, guys. That’s how the tyres on the vehicle roll back and forth. If you need new wheels, you can get branded Cheap Tyres Tamworth here.
