Abstract
A method and system for producing thin walled plastic products with hollow rib members using gas-assisted plastic injection molding. The mold is allowed to open a predetermined distance as the gas is injected into the plastic material in the mold cavity. A plurality of post members, such as ejector pins, are located on a biased ejector frame and maintain their positions relative to the mold cavity in order to form solid portions or areas in the molded part.
