Latest Patents

Thieman's latest patents include "Thermally directed die casting suitable for making hermetically sealed disc drives." This invention discloses a hermetically sealed disc drive that utilizes an aluminum alloy housing component manufactured with a thermally directed die casting press subassembly. The design features a thermally directed funnel gate that samples molten material from an off-center portion of the shot sleeve, allowing for the injection of a thixotropic aluminum alloy slurry into the die cavity. The resulting cast products are characterized by a uniform primary aluminum particle size, free of encapsulated eutectic at the micron scale.

Another significant patent is "Production of die cast rotors with copper bars for electric motors." This invention describes a rotor core for an electric motor that includes a stack of laminations with openings for copper bars. The core is mounted on an arbor and inserted into a mold on a vertical die cast press. The process involves pouring molten copper or aluminum into the mold, which solidifies around the bar end portions to form an endring for the rotor.
