How car tires are retreaded
- Retread is a sustainable re-manufacturing procedure that applies new tread to used tires.
- A retreaded tire takes 20% of the energy of used to produce a brand name brand-new tire.
- Watch makers from worldwide group Marangoni retread industrial tires.
The disposal of tires represents a significant burden on the environment, so companies like Marangoni developed approaches to recycle and reuse old tires. Enjoy how retreading machines make old tires usable again.
Following is a records of the video.
Storyteller: When your tire breaks, you take it to a shop where it’s thrown out for a new one. The disposed of tire is typically recycled – ground up and chemically broken down to utilize as a structure product in streets or parks. Some companies intend to recycle in a different way. For years, companies like Marangoni have been saving tire casings, replacing the old tread (the rubber that touches the ground) with brand-new tread in a process called “retreading.” These tires are not just much easier to make – they normally take 20% of the energy of developing a new tire – they carry out well too, standing up to the very same tests that one-use tires are subjected to.
The main benefit of the tire-retreading process comes from reusing the housings, which represents about two-thirds of the value of a new tire. Recycling tires also cuts down on the quantity of basic material utilized and CO2 produced during the industrial production process.
Let’s take a look at the retreading process detailed.
A worn tire that is to be retreaded enters the factory and undergoes visual and important checks. Important to this step is a Laser Shearography gadget, a tool that scans the tire in a vacuum to find damage or defects not visible from the outdoors in addition to separation of the plies, the group of cords and metal wires within the tire. Tires unsuitable for retreading are not disposed of, they are damaged in a thermal processing plant that burns the tires in an enclosed heater, transforming the tires into usable energy without a confined heater, converting the tires into functional energy without giving off hazardous gases. The unburned product is recuperated. Casings considered ideal for retreading are tagged with a barcode and are prepared to be rubbed.
Housings get in a maker that enthusiasts off the staying tread. The quantity of tread that’s gotten rid of differs according to the type and size of the casing. The surface area is now prepared for the application of the new tread.
The buffed casing moves to the crater processing phase. Here it is examined, and any surface area flaws are repaired. The buffed tire is coated with a sticky layer of non-vulcanized rubber or gum. A pre-vulcanized ring tread liner is stretched and fitted around the tire. A laser makes sure the maker is focused on the tire, while clamps emerge and press the tread liner down. The device holding the tread withdraws. Rollers emerge and smooth the tread liner to the case. Each tire is fitted with a rubber envelope and vacuum-sealed. They are brought to an autoclave, or pressure chamber, where each tire will be cured. The tires are at the same time subjected to immense heat and pressure. The chamber heats up to 250 ° F and imposes around 88 pounds of force per square inch for two and a half to 3 hours.
Lastly, a service technician applies the finishing touches.
