- 5. In this process the natural rubber and synthetic rubber is blended with some specific chemicals to get the rubber in the used form. Specific amount of carbon is added at the initiation of this process.
- 6. In this process the shaping of rubber takes place as the rubber sheet comes out from banbury mixer is not that perfect. This process takes place more than 2 or 3 times for the same rubber lot, just to ensure the regularity of the rubber sheet.
- 7. Extruding process is a very important process as it converts the thick and heavy rubber sheets into thin rubber sheets. Many of the tyre components are made by this process such as Tread, inner liner etc. This process is done by several different machines such as Triplex extruder, Doublex extruder etc.
- 8. Calendering is the process similar to sandwiching, as it sandwich or calender the thin and sharp steel wires between the two thin layers of rubber sheet. This process produces the steel belt which is required in the radial car tyres.
- 9. In this stage all the tyre components are assembled together to make a “ Green Tyre “ with the help of assembling machine.
- 10. This is the process where the Green Tyre is cured in a Dom shape machine having mould in its inside part at both upper and lower end. The tyre mounted on a bladder which is inside the Dom and then the both ends of it are closed and the tyre is cured in the presence of Dom Steam, High Pressure Steam, Hot Water and Cold Water.
- 11. Finishing is to be done as some irregularities are generated on and around the tyre after the curing process. It is done manually by some skilled workers. Inspection is the last stage or process of tyre manufacturing which is very important regarding tyre’s quality. It includes 3 types of inspection:- 1. Manual inspection 2. Weight balancing 3. X-ray inspection
- 12. Learned so many ways that how to prepare a tyre or mass production of the tyres effectively and efficiently. Some specific rules are necessary before doing the production. Skilled labour is required to handle the machines. And I also learned that how to work in an industrial atmosphere sincerely and systematically.
