 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.
 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.
 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.
 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.
 In this stage all the tyre components are 
assembled together to make a “ Green Tyre “ 
with the help of assembling machine.
 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.
 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
 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.
