초록

A process for injection molding hollow plastic articles includes the steps of sequentially injecting fluent plastic and gas into a mold cavity. A quantity of fluent plastic is initially injected to substantially fill the mold cavity. A charge of pressurized gas is then injected into the mold cavity to displace a portion of the still fluent plastic into a spill cavity flow coupled to the mold cavity. The article may be formed with an internal wall by introducing first and second gas charges into the mold cavity at separate entry points. In one embodiment,...

청구항

A process for injection molding a hollow plastic article comprising the steps of: injecting a quantity of fluent plastic into a mold cavity having a shape defining at least a portion of the article; displacing a portion of the plastic from the mold cavity into a spill cavity flow coupled to the mold cavity by introduction of a charge of pressurized gas into the mold cavity; permitting the injected plastic to solidify; venting the gas from the mold cavity; and removing the plastic article from the mold.
