From the outside, tyres may look deceptively simple. It’s just a piece of rubber wrapped around your wheels and filled with air, isn’t it? But millions of pounds are spent on research and development of Dunlop tyres every year. After all, Dunlop tyres are responsible for the safety and driving pleasure of drivers around the world.
To understand the reason behind it, you have to understand how far tyres have come in the past century. The first tyres were, indeed, made relatively quickly. But today’s tyres are more durable, balanced and sophisticated than ever.
Manufacturing them is an equally sophisticated job. All tyres in Sandy and elsewhere have gone through this process before taking the final form that you see on the streets. Let’s have a look at the processes that Dunlop tyres go through before they end up on the shelves of your local workshops selling car tyres in Sandy.
As you may have already guessed, rubber is the primary raw material used in making a tyre. A typical tyre uses a blend of up to twenty kinds of rubbers. These include both natural and synthetic rubber.
It’s a soft and extremely fine powder used to increase reinforcement and resist abrasion.
It is used mostly with carbon black to reduce heat build-up in performance tyres.
Textile Reinforcement Cables
These form the skeleton of car tyres around the world, like the ones you use as your car tyres in Sandy.
Chemicals like styrene-butadiene, polybutadiene, halobutyl are used for various purposes.
You might have noticed that different tyres Sandy have different patterns on them. Some of the tyres are structurally different as well. Hundreds of engineers and designers work in tandem to design every tyre.
The body of the tyre, its tread patterns and the sidewall designs are created keeping in mind the specific requirements of the type of tyres being made.
The Manufacturing Process:
The new tyres that you see on the road are a blend of over 30 ingredients. These are mixed in huge blenders called Banbury mixers. The result is a sticky black substance that proceeds to the next stage of manufacturing.
After the rubber has been cooled, it is cut into strips. Consider these strips as the basic structure of the tyre.
At this stage, the strips are placed inside a tyre-building machine along with other components such as beads, ply, tread, steel belts and the textile elements. What comes out of the device is known as a ‘green tyre’. It looks close to a finished tyre, but there are still a few hurdles to cross.
The green tyre is vulcanised in a mould at over 149 degrees Celsius and inflated against a frame. It creates the grooves, tread patterns as well as the sidewall markings.
The tyre is then inspected thoroughly by highly trained inspectors who check for any imperfection or faulty designs. Some tyres are even X-Rayed to test their structural integrity.
The end product is a robust and efficient Dunlop product that you see on the shelves when you come to buy Sandy Auto Centre Tyres.
