A method for controlling and manipulating solidification of a molten material includes generating a gradient pattern on at least a portion of a substrate and depositing the molten material on at least a portion of the substrate with the gradient pattern.

According to the present invention, between the mold-clamping process S1 in which the mold 1 is closed and the injection-pressure increase (solidifying) process S3, the gate-melting process for heating the hot runner 21 to melt the plug (metallic material) of the gate 27, the mold-lubricant coating process for spraying the lubricant onto the wall surface of the cavity 10, and the material-metering process are simultaneously carried out in parallel to each other. Thus, the molding cycle time can ...

There is provided a mold clamping apparatus which has a space-saving apparatus construction and can easily carry out mold replacement. The mold clamping apparatus includes: a base; a fixed die plate, fixed on the base, for mounting a fixed mold thereto; a movable die plate, disposed opposite the fixed die plate and movably on the base, for mounting a movable mold thereto; a mold opening/closing means for moving the movable die plate closer to and away from the fixed die plate; a plurality of mol...

A seal for a continuous casting furnace having a melting chamber with a mold therein for producing a metal cast includes a passage between the melting chamber and external atmosphere. As the cast moves through the passage, the cast outer surface and the passage inner surface define therebetween a reservoir for containing liquid glass or other molten material to prevent the external atmosphere from entering the melting chamber. Particulate material fed into the reservoir is melted by heat from th...

The invention relates to a method of operating a strip casting machine for producing a metal strip, during which molten metal is continuously poured between two casting rolls (1, 2) that form a casting gap. Lateral seals (10) having sealing plates (11) are provided for laterally delimiting the casting gap, whereby the sealing plates (11) are placed or pressed with a preset placement or pressing force, whose magnitude can be set, against the end surfaces of the casting rolls (1, 2). The sealing p...

In an injection mold including at least two mold sections which are movable relative to one another for opening and closing the injection mold and an electronic counter with an actuator and a sensor element supplying, influenced by the actuator, a signal indicative of the number of closings of the injection mold, the sensor element is disposed in a first housing and the electronic counter is disposed outside the first housing and connected to the sensor element via an electrical communication li...

Disclosed is: (i) a cap for servicing a molding-system valve, and (ii) a method of a cap for servicing a molding-system valve, amongst other things.

A diecasting machine is provided with a mold and an injection plunger to inject and fill molten metal in the mold by an advancement of the injection plunger. The diecasting machine includes an electric servomotor and a hydraulic drive source. The electric servomotor is usable as a first drive source capable of driving the injection plunger at an advancing speed lower than 1 m/sec, while the hydraulic drive source is usable as a second drive source capable of driving the injection plunger at an a...

A molding machine able to stably detect an abnormality of a squeeze pin, for example, a die cast machine having a squeeze pin able to apply pressure to a melt of a cavity repeatedly performing a molding cycle including a pressing process making the squeeze pin advance and applying pressure to the melt of the cavity in a state where the melt is filled in the cavity and a spray process making the squeeze pin advance and performing at least one of lubrication and cooling of the squeeze pin in the s...

A method for manufacturing a railcar coupler knuckle includes providing a cope mold portion and a drag mold portion. The cope and drag mold portions have internal walls defining at least in part perimeter boundaries of a coupler knuckle mold cavity. The method includes positioning one or two internal cores within either the cope mold portion or the drag mold portion. The one or two internal cores are configured to define a kidney cavity, a finger cavity and a pivot pin cavity of a coupler knuckl...
