摘要: A seal for a check valve for a metal molding machine. The seal is provided by the combination of a peripheral groove in an outer surface of the check valve and a helically wound core in the groove. The helically wound coil is expandable into sealing engagement with a cylindrical wall of the molding machine. The helically wound coil may be movable laterally in the groove between a melt channel open position and a melt channel closed position to open or seal the melt channel.

摘要: The present invention provides an improved extruder assembly, that includes a wiper for wiping a screw portion in a low pressure extruder stage, whereby the wiping of the screw portion improves melt conveyance through the low pressure extruder stage. The present invention has particular utility when used in a low pressure venting and entrainment extruder stage of a single screw compounding extruder. The present invention also provides an extrusion/injection unit for use in-line compounding molding system that incorporates the improved extruder assembly.

摘要: A check valve for a molding machine. The check valve has a stem portion and a ring portion movable along said stem portion between a melt channel open position and a melt channel closed position. A groove is formed in a forward face of the ring portion. The groove, in operation, receives melt to force an outer circumferential portion of the ring in a radial direction to provide a seal between the ring portion and a wall in the machine.
