Tire components, curing belts

Typically, the compounded rubber stocks need to be further processed for use. The process could be an injection or transfer molding into a hot mold, where it is cured. Extrusion of the rubber stock is used to make hose or tire treads and sidewalls. Another common process is calendaring, in which a fabric is passed through rolls where rubber is squeezed into the fabric to make fabric-reinforced rubber sheets for roofing membranes, belting or body plies for tires. The actual construction of the final product can be quite complex. For example, a tire contains in excess of six different compounded elastomeric stocks. All the components must be prepared and assembled with high precision so that the final cured product can operate smoothly at high speeds and last over 50,000 mi.
