Manufacturing process:

The manufacturing process of tire can be broadly be classified into three stages, mixing(compound preparation), building (assembling) and vulcanizing (curing) process.
In mixing process the crude and synthetic rubber are weighed and masticated.
Mixing takes place in Ban bury mixer followed by an open mill dump roll for cooling and further dispersing ingredients which may not fully homogenized during the mixing process in the mixer.
The mixing is taking place either in temperature or time base, the moment the mixed compound reach the set time or temperature, the mixer discharge door opens automatically and dup the material to the open mill.
The compounds prepared in this way, after insuring the required physical and mechanical property parallel with the process test, are met as quality criteria, the materials released for further process like for tread extruding, cord rubberizing, bead making, etc to prepare the semi finished materials/or components of the tire for assembly.
The green tire is built-up as a cylinder on a collapsible, round rotating drum. Layers of cords embedded in a proper compound are applied, one layer tying the heads together in one direction and another layer in another direction. The heads – wire cables embedded in a tough, hardrubber – are “stitched” to the tire by folding the end of the cord fabric over.
The tire building drum is collapsed, and the cylindrical tire removed and placed in a press. Butyl made curing bladder, that resists high temperature and frequent fatigue is used as a media holder for the curing of the inside part of the tire through which hot water or steam is circulating. For the outside part of the tire the media is circulating between the curing press dome and the tire mould through conduction heat transfer.
The bladder is also help the green tire to get blown up inside the tire and shape it to the cavity of the curing mould; the press mould is simultaneously closed, and the tire becomes a doughnut. Heat is applied through the mould and by steam inside the bag.
After a timed cure at pre selected temperature, the tire is formed.
The green tire is inserted into Auto form curing press for an automatic vulcanization.
The tube operation more or less uses the same operation in which the compound come from mixer will be extruded as hollow tube which is dusted both inside and outside and after cooling, the tube cut to the length, extra dust will be de-dusted, valve is applied in specified location, the green tube then spliced.
After having adequate rest time the tube then pre-shaped to 85% of the final tube through air in the forming ring and then inserted to the curing mold and then after curing the tube will be inspected for any defect and released for warehouse for sale.
