    Abstract: An injection molding system and methods for improving performance of the same. The system includes a plunger rod and a melt zone that are provided in-line and on a vertical axis. The plunger rod is moved in a vertical direction through the melt zone to move molten material into a mold. The injection molding system can perform the melting and molding processes under a vacuum. Skull formation in molten material is reduced by providing an RF transparent sleeve in the melt zone and/or a skull trapping portion adjacent an inlet of the mold. It can also be controlled based on the melting unit. Vacuum evacuation can be reduced during part ejection by using a plunger seal, so that evacuation time between cycles is reduced.

    Abstract: A metal matrix composite using as one of the components a precious metal is described. In one embodiment, the precious metal takes the form of gold and the metal matrix composite has a gold mass fraction in accordance with 18 k. The metal matrix composite can be formed by blending a precious metal ( e.g. , gold) powder and a ceramic powder, forming a mixture that is then compressed within a die having a near net shape of the metal matrix composite. The compressed mixture in the die is then heated to sinter the precious metal and ceramic powder. Other techniques for forming the precious metal matrix composite using HIP, and a diamond powder are also disclosed.
