Patents by Inventor Shugo MATSUZAWA

Shugo MATSUZAWA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Die casting machine, die casting machine equipped with dies, control device for die casting machine, and die casting process
    Patent number: 11911820
    Abstract: A gap control part controls a clamping device so that mating surfaces in a die face each other across a gap, and thereby a cavity and an external part of the die communicate across the gap. A molten metal feed control part controls a molten metal feed device so as to feed molten metal into a sleeve when the gap is being maintained. An injection control part controls an injection device so as to start a forward movement of a plunger at a time when the gap is maintained and there is the molten metal in the sleeve. A clamping control part controls a clamping device so as to make the mating surfaces abut against each other to eliminate the gap after the forward movement of the plunger is started and before the molten metal reaches a molten metal surface height at which the molten metal flows into the gap.
