An apparatus and method are provided that increase yield and reduce cycle time. In particular, a gate plate for a die casting machine is configured to lessen the waste produced during die casting, resulting in greater yield. Further, the gate plate is configured with tapered sides to produce a draft, leading to less friction during the gate break/pull back sequence. This draft reduces the amount of unpressurized dwell time and subsequently the cycle time for producing the cast part.

Optimized tooling design for vertical die casting machines

To cast a part, an injectable form of an aluminum-copper (206) alloy is generated and the aluminum-copper (206) alloy is injected into a mold. This mold corresponds to the part. In addition, the aluminum-copper (206) alloy is solidified to generate the part and the part is ejected from the mold.

Squeeze and semi-solid metal (SSM) casting of aluminum-copper (206) alloy

A method for the refining of primary aluminum in hypoeutectic alloys by mixing a titanium based grain refiner into a solid/semi-solid hypoeutectic slurry is described. The method provides control of the morphology, size, and distribution of primary Al in a hypoeutectic Al&#x2014;Si casting by mixing a hypoeutectic Al&#x2014;Si liquid with titanium boron alloys. The invention enables grain refining techniques for SSM casting of hypoeutectic Al&#x2014;Si alloys.

Semi-solid casting process of aluminum alloys with a grain refiner

A method for the refining of primary silicon in hypereutectic alloys by mixing at least two hypereutectic alloys into a solid/semi-solid hypereutectic slurry is described. The method provides control of the morphology, size, and distribution of primary Si in a hypereutectic Al&#x2014;Si casting by mixing a hypereutectic Al&#x2014;Si liquid with solid hypereutectic Al&#x2014;Si particles. The invention enables SSM processing of hypereutectic Al&#x2014;Si alloys.

Semi-solid metal casting process of hypereutectic aluminum alloys

A method for the refining of primary aluminum in hypoeutectic alloys by mixing at least two hypoeutectic alloys into a solid/semi-solid hypoeutectic slurry is described. The method provides control of the morphology, size, and distribution of primary Al in a hypoeutectic Al&#x2014;Si casting by mixing a hypoeutectic Al&#x2014;Si liquid with solid hypoeutectic Al&#x2014;Si particles to impart desirable mechanical properties. The invention enables SSM molding of hypoeutiectic alloys without the need for secondary processing steps associated with other rheocasting processes.
