Abstract

A method wherein an article is molded of liquid plastisol in a mold having mold heaters disposed adjacent the backside of a mold surface for controlling the temperature over respective first and second areas of the mold surface. First and second heating and cooling circuits are associated with each mold. To obtain liquid plastisol coating, the mold is filled by apparatus including a removable insert that reduces the quantity of plastisol that is used in the process to reduce the cycle time required for part molding. In one process, plastisol is pumped into and is removed from the mold with the mold insert in place. In another process the mold insert is removed from the mold and an intake tube remains in the mold to pump out excess material.
