  • Patent number: 5304341
    Abstract: A plastics injection molding machine includes an injection mold having a cavity for molding a part with channels of relatively larger and smaller volumes. Plastics material and pressurized gas are injected into the cavity and are forced to flow into the channels. A flow restricting element is selectively extendable into the smaller volume channel to decrease the rate at which the plastics material flows into the smaller volume channel in order to balance the distribution of plastics material and gas among the channels, and develop a part with substantially uniform cross-sectional material wall thickness desired gas penetration length in hollow channels.

  • Patent number: 5251403
    Abstract: A mounting panel is provided for mounting a window and a window regulator in a vehicle door. The mounting panel is comprised of a one-piece plastic molded member having a central planar mounting member adapted to mount the window regulator, and a plurality of spaced apart spokes molded integrally with the center drill plate and radiating generally forward and rearward therefrom to mount the guide channel receiving the edges of the window. The window guide channels are preferably integrally molded with the radiating spokes. The spokes are hollow tubular members of generally circular cross-section. The molded plastic mounting panel also has a plurality of integrally molded arm rest supports which project laterally therefrom and are adapted to support an arm rest structure of the vehicle door. The plurality of apertured mounting brackets are molded integral with the spokes for receiving fasteners by which the mounting panel is mounted on the vehicle door.
