A method for accelerating the creep age forming of a metallic component is provided. The method includes the steps of applying static loading and ultrasound vibrations to the local regions on a metallic component during the creep age forming process. The transmission of ultrasound in the component enhances the mobility of dislocations and atoms and thus accelerates the creep deformation in the component.

A method for producing a vehicle wheel from a light metal material is disclosed herein. The light metal material is introduced in liquid form into a mold cavity of a casting mold and pressurized casting is then used to produce the vehicle wheel. The casting mold is temperature-controlled, where different regions of the casting mold are maintained at different temperatures. An apparatus that includes the disclosed casting mold is also described herein.

A product state estimation device includes: an examination result acquisition device that acquires an examination result related to a state of a product obtained through each shot by a die-casting machine; a time series data acquisition device that acquires time series data based on an output from a sensor that detects an operation state of the die-casting machine at each shot; a time series data manipulation device that performs manipulation that clips data of a predetermined time interval out of the time series data; an estimation model generation device that generates an estimation model by using a neural network with the examination result of the product and the manipulated time series data as learning data; and an estimation device that estimates information related to quality of the product based on the manipulated time series data obtained from a plurality of detection signals at each shot by using the estimation model.

A pressure intensifier device increases pressure in a pressurized fluid chamber of a piston/cylinder unit. The pressure intensifier device has a pressure intensifier cylinder and a pressure intensifier piston, which is guided in an axially movable manner in the cylinder, wherein the pressure intensifier cylinder has an outlet region, an inlet region upstream of the outlet region and a piston guiding chamber, and the pressure intensifier piston has a piston part, which is guided in the piston guiding chamber, and a piston rod, which extends from the piston part to the inlet region, in a maximally retracted release position releases a fluid connection between the inlet region and the outlet region and, in a maximally advanced blocking position, blocks this connection with a free end portion, with which it extends into the outlet region. Over a portion that can be passed through by the free end portion of the piston rod during movement from the release position into the blocking position, the outlet region has a free passage cross section for the free piston rod end portion that is at least equal in size to a rod cross section of the free piston rod end portion. A pressure intensifier inlet valve can be controlled independently of a pressure in the pressurized fluid chamber of the piston/cylinder unit.

A smart trim die assembly for providing multiple internal operations during a stroke. The smart trim die assembly (10) comprises a first die (12), a second die (14), and a cavity (20) formed between the first die and second die. A plurality of sensors (22) are located between the first die and the second die for measuring the distance therebetween during a stroke. A series of tools are integrated into one of the first die or second die and each perform one of trimming, piercing, dimpling, and tapping operations. The smart trim die assembly further includes a processor (210) and a memory device (214) for receiving readings from the sensors. The memory device further contains instructions that, when executed by the processor, cause the processor to, in response to the sensor reading a predetermined distance, instruct the series of tools to perform one or more of the operations.
