däcktillverkningen

Däcktillverkningen, or tire manufacturing, is the industrial process of creating rubber tires for vehicles. It is a complex, multi-stage process that begins with raw materials and ends with a finished product ready for use.

The primary raw materials are natural rubber, derived from the latex of rubber trees, and synthetic rubber, which is a petroleum-based product. Other key ingredients include carbon black, which provides strength and wear resistance, various chemicals like sulfur for vulcanization, and reinforcing materials such as steel and textile cords.

The manufacturing process typically involves several steps. First, the raw materials are mixed in precise proportions to create a rubber compound. This compound is then processed through various stages, including extruding or calendering to form specific shapes for different tire components like the tread, sidewalls, and inner liner.

Next, these components are assembled onto a tire building machine. This machine layers the different parts, including the carcass plies and bead components, to form an uncured tire structure. Finally, the assembled tire is placed into a mold and subjected to high heat and pressure in a process called vulcanization. This process cures the rubber, giving the tire its final shape, strength, and elasticity. After curing, the tires undergo inspection and quality control before being shipped to distributors and consumers.
