5. TYPES OF TIRE
• All the basic construction of all types of tires is same but the quality & rubber used is
different.
• For example in summer tires Hard rubber is used & in winter tires soft rubber is used

6. TIRE BUILDING
PROCESS
Collection of
Raw Material
Rubber is drawn
into sheets
Rubber sheet are rolled

7. CURING
It is a process of vulcanization of rubber.
It holds two main parts upper mold & lower mold
Mainly there are
• Sulfur systems
• Peroxides
• Urethane cross linkers
• Metallic oxides
• Acetoxysilane

8. CURING WITH SULPHUR
In curing process shlphur is mixed with water due to high solubility,
then the solution is send to curing press where hydraulic pressure is
1.8-2.1 MPa (Mega Pascal's) & air pressure is 0.25-0.35 MPa &
Temperature 170 °C for 10 minute
After in the above curing process RTV ( Room Temperature Vulcanization)
process is done. In this process silicon reactive oil polymers are constructed & this
oil is pasted on tires to get extra strangeness

9. CURING PRESS
 BOM: - BAG-O-Matic types are most modern & are widely used.
Bladder is open ended cylindrical shaped. Tire is ejected from bladder by
applying vacuum.
 NRM: - Bladder is pot shaped with its upper end closed. Bladder is sunk
in bag well by ram & lifts the tire from mold.

10. RADIAL TIRES
Radial tires are generally known as nylon or off road tires.
 First layer is of rubber sheet
 Second sheet of steel
 Third layer of rubber
 Fourth layer is of nylon
 Final layer of hard rubber

11. LUBRICATION
Lubricants are made up of vegetable oil extracts.
The Industry-approved Rubber Lubricant are used. Lubricates are
used for mounting and demounting of tires. Lubes is must for all
tires to protects beads against scuffing during mounting-assures
proper bead seating on rim. Protects against tire slippage after
mounting. Also removes rubber squeaks in bushings and grommets.

12. FINAL INSPECTION
Final inspection is done on various points
 Quality standards
 Proper grip
 Air pressure
 Proper design

13. INSTRUMENTATION
PART IN INDUSTRY
Allen Bradley's PLC’s &
Counters for Counting the Curing Time in Press
