초록

A gas assisted injection molding method and apparatus wherein articles are produced by injecting molten resin into a mold cavity and then injecting a quantity of pressurized gas into the resin to fill out the mold cavity and form a hollow in the resin. Following the injection of the gas into the resin to form the hollow, gas is injected into the resin in the mold cavity at a second location. The gas injected at the second location may either form a separate hollow within the resin or may form a passage extending through the resin for communication with t...

청구항

A method of providing gas assistance to a resin injection molding process in which hot resin is injected into a mold, gas is injected into the resin to fill out the mold cavity, the resin cools, the gas is vented, and the mold is opened to remove the molded part, characterized in that the gas is injected into the resin at a first location to form a gas hollow within the resin and completely fill out the mold cavity with resin and is thereafter injected into the resin at a second location spaced from the first location to form a second hollow within the r...
