Procedure 1: Internal mixing process
The internal mixing process is the process of mixing carbon black, natural/synthetic rubber, oil, additives, accelerators and other raw materials together and processing them in the internal mixer to produce "rubber".
Procedure 2: Rubber parts preparation process
The preparation process of rubber parts includes six main sections. In this process, all semi-finished rubber components that make up the tire will be prepared, some of which have been preliminarily assembled. The six sections are:
Section 1: Extrusion
The rubber is fed into the extruder head to extrude different semi-finished rubber parts: tread, sidewall/sub-mouth and triangular rubber strip.
Section 2: Calendering
The raw material cord passes through the calender and a thin layer of rubber is hung on both sides of the cord. The final product is called "cord". The raw material cord is mainly nylon and polyester.
Section 3: Bead forming
The bead is made by winding many steel wires after hanging glue. The compound used for bead has special properties. When vulcanized, the compound and steel wire can be closely bonded together.
