Production process
Step one: mixing step
Mixing step is to carbon black, natural / synthetic rubber, oil, additives, accelerators, etc. raw materials are mixed together in the mixer was processed to produce "gum" process.
Step two: plastic parts preparation step
Plastic parts preparation process includes six main station. In this process, the semi-finished products will be ready for all rubber components of the tire, some plastic parts are assembled preliminary. This six section are as follows:
Section one: extrusion
Rubber material fed into the extruder head, thereby extruded semi-finished products of different plastic components: the tread, sidewall / bead and bead apex.
Section II: rolling
Raw cord through the calender and cord are hung on both sides of a thin layer of plastic material, the finished product is called "cord." The main raw material for the nylon and polyester cords of two kinds.
Section III: bead molding
After the bead is formed by a number of winding wires hanging plastic. For the bead of this compound have a special performance, when after a vulcanized, rubber and wire to tightly fit together. |
