A multilayer window guiderail is disclosed. The window guiderail includes a rail portion having an outer edge, a rail surface and an opposing rear surface. The rail portion includes a core and an integral rail cover layer disposed on the core. The core includes a first polymer material and the rail cover layer includes a second polymer material. An apparatus for making a multilayer guiderail includes a plurality of die portions having respective cavity portions. The cavity portions are configured to define a die cavity having the shape of the guiderail, at least one of the die portions being a slidable die portion and at least one of the die portions being a fixed die portion. The parting surface of the slidable die portion is configured for sliding translation of its parting surface over the parting surface of the fixed die portion along a translation path.

A gas injector having a retractable nozzle with linear gas feed passage therethrough for a gas assist plastics injection molding machine. The injector interfaces with the injection molding tool and has a nozzle with a tip that, in a forward position, protrudes through a port therein leading into the tool cavity or a runner system leading into the cavity for gas injection during molding. The nozzle tip is connected by a nozzle body to a base that is operatively mounted in an actuator housing. The base is connected to an in-line gas routing extension of the nozzle that projects through the outer cover of the housing. The extension is coaxial with an internal spring that seats on the base and holds the nozzle tip in a gas injection position resisting the force of plastics injection pressure. The base connected nozzle is retracted by combined flux fields of an electromagnet and a permanent magnet mounted within the housing while compressively loading the spring enhancing gas release from the cavity tool separation and subsequent ejection of molded part. The electromagnet is then deenergized since the permanent magnet has a sufficient magnetic force field to, hold the base and the attached nozzle in the retracted position. For return to the gas injection position, the electromagnet is again energized but with the current supplied thereto reversed so flux field of the electromagnet is reversed to negate flux field of the permanent magnet allowing the spring to return the nozzle to the forward position.

A method of extruding a profiled strip of polymeric material off the extrusion die of a plastic extruder and immediately thereafter compression forming a predetermined section of the profiled strip into a predetermined shape when temperature of the polymeric material is sufficiently high to allow plastic flow in the profiled strip. The method including the steps of first extruding a profiled strip of polymeric material through the extrusion die and compression molding a predetermined section of the profiled strip into a predetermined shape at a close proximity from the extrusion die with a set of compression molding dies capable of traveling with the profiled strip at substantially the same speed for a sufficient length of time to permanently set the predetermined shape, disengaging the compression molding dies from the profiled strip at a predetermined distance from the extrusion die; cooling the profiled strip having the compression molded predetermined shape in a suitable cooling fluid such that the predetermined shape is permanently maintained, and then trimming the extruded profiled strip into discontinuous pieces each having the compression molded predetermined shape.

Apparatus for pulsating gas-assisted injection molding hollow tubular plastic parts includes the injection of a molten plastic into a mold cavity in an amount less than the cavity volume and in separate molten plastic flows that flow along the cavity and ultimately unite in a solidifying fusion welding state at an interface. A pressurized gas is injected into the molten plastic to form a central void in the molten plastic extending to opposite sides of the interface leaving a voidless solidifying fusion weld section encompassing the interface. The gas pressure acting on the opposite sides of the interface is trapped and then alternately increased and decreased by a separate gas injection that creates gas pulsations that effect shifting of the molten weld section in opposite directions to force intermingling of the plastic molecules therein and across the interface to enhance the strength of the fusion weld section on solidification and eliminate appearance knit lines. Reinforcement fibers may be included in the molten plastic and the shifting of the molten weld section orients a number of the reinforcement fibers generally parallel to each other and transverse to and extending across the interface to thereby enhance fusion weld section strength.

Tooling and method for gas assist injection molding of plastics material into a hollowed part in which a mold chamber formed between stationary and movable mold tools is initially charged with an inert gas to provide a resistance force against the flow front of a short shot of plastics melt subsequently injected into the cavity and supplied with a pressurized assist gas so that the velocity of the flow front of the short shot expanded by the assist gas in the mold chamber is modulated by the controlled release of the retarding chamber charge gas to prevent blow out of the short shot while eliminating flow hesitation lines to improve molded part appearance and uniformity of part wall thickness.
