THIXOTROPIC INJECTOR WITH IMPROVED ANNULAR TRAP |
摘要 |
<p>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.</p> |
