A punch head comprises a low profile hydraulic anvil piston with a punch across from a die on opposite sides of a gap between two legs. One of the legs comprises a position sensor disposed on the bottom of the leg. For example, a plurality of punch heads are disposed on a jig or frame and are positioned using one or more of the position sensors. For example, the position sensor is a mini fiber optic position sensor mounted in a recessed portion at the bottom of one or more of the punch heads.

A die casting machine has a carousel and a plurality of molds disposed around the carousel. The carousel rotates about a central axis, such that each of the plurality of molds comes into a position for casting in turn. Each mold has a toggle mechanism and extraction pins. A gripping mechanism may extend up through a hole in the carousel table to couple the toggle mechanism to an actuator. At least one of the pins may have a pin brake such that the pins remain in position when the mold is opened, suspending a newly cast metal part in mid-air, when the brake is activated. When the brake is deactivated, the pins may retract, and the part may be removed without damaging the cast part.
