ABSTRACT:
An injection molding machine for thermoplastic and thermosetting materials is provided with air pressure as the sole means other than gravity for moving particulate or powder form of the plastic through the heat cylinder of the machine whereby the plastic power is converted to a viscous molten liquid that is forced through the nozzle of the machine into an orifice of a mold where, after setting, a plastic article can be removed.
