Granted: 2007-08-01
Abstract: A die casting machine (18) includes a melting unit (24), a horizontal shot sleeve (30) in fluid communication with die cavity (36) for receiving molten titanium from the melting unit (24), and a plunger (40) sealing and moveable engagement with the shot sleeve (30) for forcing molten material from the shot sleeve (30) into the die cavity (36). The melting unit (24), the shot sleeve (30) and the die cavity (36) are maintained in a non-reactive environment. The material is melted to a low superheat, e.g. less than about 200  DEG F/95  DEG C. Molten material is then transferred from the melting unit (24) to the shot sleeve (30) to fill not more than about one half of the shot sleeve volume. The molten material is injected from the sleeve (30) into the die cavity (36) using the plunger (40) for solidification in the die cavity (36). The resulting articles have a fine average grain microstructure and are characterized by an absence of flowlines.

Abstract: An improved method of and apparatus that is continuously automatically operative in an in-line system is described for applying under heat, vacuum and mechanical pressure a dry film photoresist-forming layer to printed circuit boards (136) that already have been prelaminated by the loose application thereto of the dry film resist as discrete cut sheets within the confines of the surface of the boards whereby a laminate without entrapped air bubbles and closely conforming to the raised circuit traces and irregular surface contours of the printed circuit board is obtained. Featured is a conveyorized vacuum laminator (18) comprising heated upper and lower platens (96,94) adapted to be moved into sealing engagement to form a vacuum lamination chamber (16), and disposed between the platens are two independent belt conveyor systems (20,22) that act as heat shields to prevent the printed circuit board and the loosely applied dry film from being heated up too rapidly in the vacuum chamber by the residual heat given off by the upper and lower platens before the film can be completely evacuated. This prevents premature tacking of the dry film to the board and enables all of the air entrapped between the film and the board surface to be drawn off before the application of heat and mechanical pressure, so as to ensure complete conformance of the dry film around the circuit traces and surface contours.  <IMAGE>
