<p>A mold used for forming an elastomeric article such as a tire under heat and pressure is provided with small grooves at selected locations along the internal cavity walls to reduce or eliminate flash which customarily forms at these locations. Specifically, grooves are provided at the structural interfaces of replaceable mold components, such as tread and bead rings with cavity wall portions of the mold sections. The grooves operate to trap or collect elastomeric material extruded into the interfaces and provide a seal-like barrier into further flash.</p> |
