All Process of the World takes us inside a Kumho tire factory in Vietnam that cranks out thousands of tires each day. They start with large quantities of rubber and other materials and extrude those into long, flat strips. Then machines cut and mold them around a circular form, apply layers, attach an inflatable structure, then heat-emboss tread patterns.
Ever wonder how they make basketballs or other bouncy rubber balls? It’s not as simple as just blowing up a rubber balloon. Science Channel’s How It’s Made visited a ball factory to walk us through the fascinating process, which includes making an inflatable bladder, then wrapping it in nylon thread and a segmented rubber skin.
Everyday car tires are made mostly by machine, but the high-end tires used for racing are made by hand. In this clip from Street FX Motorsport TV, they take us inside Michelin Motorsport’s HQ in France for a look at the tire-making process, building up layer by layer of rubber, textiles, steel, and adhesive on spinning drums.
