摘要： A semi-solid metal alloy injection feed system for reduced inclusion injection moulding comprises a substantially closed injection chamber for containing a billet of semi-solid metal alloy, and thrusting the billet through the injection chamber into a mould, wherein the injection chamber has a first section defined by a wall with an inner contour for mating with a bearing surface for reciprocating motion of the bearing surface within the first section, along a center axis of the injection chamber; and the injection chamber has an outlet in fluid communication with the mould, the outlet provided at an opening in the injection chamber that is offset with respect to the center axis, and is disposed at an angle of 90° to 125° from the center axis. There is no neck or throttling between the chamber and the outlet. A butt end trap is preferably formed that requires inclusions that are principally on a bottom side of the injector to travel a relatively long ways to enter the outlet.

摘要： By blocking an angular extent of an annular skimming trap used for semi-solid injection, a notable reduction in lenticular defects and porosity are observed. The blocking can be performed by a ring having dimensions to completely occlude a prior art annular skimming trap throughout the angular extent, and providing complete and/or partial flow across the ring throughout the rest of the angular extent. Preferably an outlet to the ring trap includes a chamfered edge and/or a deflector for encouraging flow of the contaminated semi-solid material into the trap.
