How tires are manufactured?
The first stage of tire making is collecting raw materials and
formulating rubber compounds. The raw materials used are rubber,
oils, pigments, antioxidants, carbon black or silica,
accelerators and other additives. These are then mixed together
in a huge blender, which is called Banburys. After the mixing
process is completed a gum like material forms. This material is
then cut into strips. These strips will make the sidewalls and
other portions of the tire. The main body of the tire is
manufactured using fabricated rubber. Polyester, nylon and rayon
are the fabrics used. The fabrics are changed depending on the
type of the tire. But mostly Polyester is used. Another ring
like component is used to make a tire. This is called tire bead.
Steel wires of high tensile are used to make this tire bead.
Radial tires are made in a cylindrical tire-building machine.
The machine almost gives the final shape of the tire. After the
making of the tire, it passes through an assembling process.
Tires are assembled from the inside out. The inner line of the
tire is made of two layers of synthetic rubber. Then another
double layer of poly fabric is pasted. Then follows two trips of
apexes to harden the area. Then 2 chafer strips are then pasted.
Then automatic rollers press all parts. It helps all parts to
bind. After an inspection the tire goes for curing process. In
the curing process the tire is heated to the temperature of
300
