Abstract
There is disclosed a mold comprising a first mold portion and a second mold portion engageable to define a mold cavity in a closed position of the mold. The first mold portion comprises a first part-line surface and the second mold portion comprises a second part-line surface. The first part-line surface comprises a projection portion and the second part-line surface comprising a resilient portion for substantially sealing engagement with the projection portion in the closed position of the mold. The present mold allows for the production of a so-called “positive seal” between the two mold halves at the part-line of the mold, particularly in the areas of the part-line where there is no vent. This allows for production of a molded part having minimal or no flash produced at the part-line of the mold.
