Abstract:
A monolithic injection molded plastic part including an interior core, a surface formed as a monolithic structure with the interior core, and a distribution of hollow cells formed within the interior core during an injection molding process from a blowing agent and methods for making the same are provided. Such methods include preparing a mixture of unmelted plastic resin, filler agent, and blowing agent, melting the mixture into a viscous combination using a standard injection molding machine, injecting a set amount of the viscous combination into a hollow cavity of an injection mold secured within the standard injection molding machine, and holding the set amount of the viscous combination in the hollow cavity at a low pressure for a hold time until the viscous combination sets into a monolithic structure at least partially filling the hollow cavity and the blowing agent forms a distribution of hollow cells throughout the monolithic structure.

Claim (Index 16):
A method for manufacturing an injection molded plastic part using an injection molding machine having a mold secured therein, a first part of the mold being secured to a movable platen comprising:\n heating multiple heating zones of a barrel of the injection molding machine to respective set temperatures; after the respective heating zones achieve the respective set temperatures, feeding a mixture comprising an unmelted plastic polymer resin, chemical blowing agent, and glass bubbles into the barrel in order to allow plasticization of the mixture into a viscous combination; beginning a mold cycle by rotating a feed screw inside the barrel to an initial shot size; moving the movable platen to a first set point fully opening the first part of the mold and a second part of the mold; moving the nozzle forward until the nozzle is seated up against a circular sprue of the mold; moving the movable platen from the first set point to a second set point at a first rate and a first pressure; moving the movable platen from the second set point to a position holding the first part of the mold and the second part of the mold open at a distance; pushing the screw ahead toward the nozzle at a second rate and a second pressure for a first preset time period to inject the viscous combination into the mold until the mold is at least partially filled; when the screw reaches a cutoff distance from the nozzle, holding the first part of the mold and the second part of the mold open at the distance for a second preset time period at a low pressure to allow the chemical blowing agent to expand the viscous combination and fill out the rest of the mold; cooling the mold for a predetermined time; and following expiration of the predetermined time, ejecting a part formed from solidifying of the expanded viscous combination from the mold.
