Latest Patents

Tajima holds a patent for a die casting method and die casting machine. This invention provides a unique process that involves evacuating a cavity defined by dies to create a vacuum of 100 millibar or less during a first period. It includes the injection of a reactive gas into the cavity during a second period, which overlaps with the first. This method increases the inner pressure of the cavity to atmospheric pressure or more, allowing for the effective pouring of a molten aluminum alloy while minimizing the incorporation of gases. The result is a die-cast product with significantly reduced volumes of incorporated gases, making it suitable for functional applications.
