Abstract
Method and apparatus for making a cast product shape using a die casting method wherein a molten metallic material is introduced into a shot sleeve having an end that is closed by a movable closure member. The molten metallic material is forced by movement of a plunger in the shot sleeve to the closed end of the shot sleeve where the plunger maintains pressure on the metallic material until it is at least partially solidified in the shot sleeve in the form of a cast product having a outer peripheral shape corresponding to the inner peripheral shape of the shot sleeve. The end of the shot sleeve then is opened by relative movement of the closure member and the shot sleeve, and the plunger is moved further to eject the product shape from the open end of the shot sleeve.
