Patents by Inventor Davide Brondolin

Davide Brondolin 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 piston and ring assembly
    Patent number: 9829108
    Abstract: The invention relates to a die casting ring (1) internally fitted with radial teeth (11) to be engaged into matching seats (22) provided on a piston (2). This piston-ring assembly prevents mutual rotation or axial translation, in addition to ensuring an optimal seal against infiltration of liquid metal during the die casting process. When the ring has a cutout (10), it can be mounted accurately onto the piston because the teeth (11) allow the cutout to be positioned anywhere relative to the piston.

  • Die casting cooled pistons
    Patent number: 9550233
    Abstract: A pressure die casting piston assembly has a pressure die casting piston. The die casting piston has a front head, a substantially cylindrical side wall extending upwardly from the front head in fixed position relative thereto. A cup-shaped chamber is defined by the front head and the side wall. The side wall is closed by the front head. The die casting piston has a coolant channel passing through the side wall to allow a coolant to pass through the side wall and within the side wall.

  • Die casting cooled pistons
    Patent number: 8931543
    Abstract: The invention relates to a die casting piston (20) and a respective support (2). The piston has a wall (21) in which channels for a coolant flow are obtained: this improves the thermal exchange between the piston and the coolant, leading to greater cooling efficiency.
