Abstract:
Quality of a tvre is highly dependent on the tyre moulds that are being used to produce
tyrcs. It has been found that in most of the situations. tyres are rejected due to defects and
other problems arising from the existing poor quality moulds. The present tyre mould
production process (dry sand casting method) has inherent drawbacks and difficulties in
both casting and finishing processes. Dimensional accuracy and the geometry of moulds
are hard to achieve. Moulds crack during use due to internal blowholes introduced In
casting process and it is difficult to eliminate these defects in the present method.
