Abstract: An apparatus for molding electronic components. The single-strip molding apparatus has a mold die formed from two mold halves which are movable relative to each other and can be closed upon one another. A leadframe for the component to be molded is placed into a recess in one of the mold halves. Molding material is heated and forced under pressure into the recess containing the leadframe. After the component is molded the mold is opened and the upper half of the mold is cleaned by a combined cleaning-discharge unit. Upon the return stroke of the cleaning-discharge unit, the molded component is removed and the lower half of the mold is cleaned.

The die (14) is movable axially to the container (20) or vice versa. The container (20) defines at least two chambers (19) and is movable in a plane perpendicular to the plane on which the axis of the chamber (19) and the die (14) lies. An extrusion plant which includes a press as described above is also disclosed. The extrusion plant includes three stations that perform extrusion (19a), charging (19b) and the cleaning and readying of chambers (19c) respectively, the stations cooperating respectively with the chambers (19).

Abstract: For an injection molding machine a nozzle touch plate is provided which is slidable on a surface of a stationary plate opposite to the surface to which a metal mold is secured. The nozzle touch plate is brought to a position for preventing advancement of an injection nozzle into contact with the metal mold. In this position, the injection nozzle is brought into contact with the nozzle touch plate so that resin remaining in the injection cylinder is purged against the plate at the time of changing the type or color of the resin whereby the resin is prevented from being injected into the metal mold. After purging the nozzle touch plate is retracted to permit injection molding of new resin.

Abstract: An improved apparatus is disclosed for the production of particulate metal comprising a containment vessel having a sidewall extending to an endwall, a source of metal external to the vessel, nozzle means carried by the endwall, the nozzle means including a central bore and providing communication between the vessel and the external source of metal, the sidewall and endwall cooperating with the nozzle means to seal off the interior of the vessel and the metal particles therein from the area adjacent the source of molten metal, a source of atomizing gas flowing through the nozzle means into the vessel, and means for removing depositions in the bore including a source of purging gas directable into the bore.

Abstract: Apparatus is provided for the production of atomized metal comprising a containment vessel having a sidewall terminating in a bottom plate through which atomizing gas and molten metal from a molten metal source external to said vessel enter said vessel through nozzle means sealed thereto. An air ingress port is provided in the vessel spaced from said bottom plate; the sidewall and bottom plate cooperating with said nozzle means to seal off the interior of the vessel and the metal particles therein from the area adjacent the source of molten metal; thereby providing an essentially closed vessel, particularly with respect to the area in which the nozzle means are mounted.

Abstract: A method and apparatus for cleaning at least selected surfaces of a mold apparatus to remove plastic residue and surface contaminates and impurities to enable the molds to be used in a continuous in-line type process for encapsulating lead frame assemblies or similar semi-conductor circuits. After the molds are separated and the large pieces of excess plastic are broken away, they are transported to a vacuum chamber and electrically coupled as, or at least proximate, the cathode. The vacuum chamber is evacuated and an inert ionizable gas such as argon is admitted. An electrical field is established between the anode and cathode to create a plasma or glow discharge causing the gas to ionize. The positive ions are accelerated by the electrical field toward the cathode and bombard at least selected areas of the mold portion to be cleaned for removing surface contaminates and producing an extremely clean surface to enable the mold portion to be used again and again in a continuous cyclical or in-line process.

Abstract: A bolster pin is provided which automatically cleans the flask bushing of a mold set. The bolster pin has brushing elements which clean the flask bushing each time the mold set is joined or separated. Use of the bolster pin provides a method for automatically cleaning the flask flange bushing of entrapped sand.

Abstract: An improved apparatus for the production of particulate metal is disclosed. The apparatus includes a containment vessel having a sidewall and a bottom plate, a source of metal external to the vessel, nozzle means carried by the bottom plate and providing communication between the vessel and the external source of metal, and release means associated with the sidewall to inhibit deposition of the particulate metal on the sidewall.

Abstract: An automatic foam dispensing system is described for forming shock-absorbing members of synthetic foamed material into predetermined shapes at pre-selected locations inside a container for the cushioning of articles to be provided therein. The foam dispensing system is generally constructed from a dispensing booth having a plurality of synthetic foam dispensing apparatus provided thereat and a plurality of mold assembles adapted for movement along a track to and from the dispensing booth.

Abstract: An apparatus and method for forming components having one or more inner cavities wherein material forming the component is laid up about a number of eutectic salt mandrels corresponding to the inner cavities. The mandrels are melted and the laid up material compressed during the formation of the component by hydraulic pressure transmitted through the molten mandrels.

Abstract: A system for production of non-woven sheet material by the dry forming method, comprising a moving carrier web to receive a uniformly distributed layer of loose fibres and a fibre distributor unit located above and across the moving web. The distributor unit includes a closed conduit system for conducting a flow of air fluidized fibre material, this closed flow across the web being maintained by blowing action. The conduits located overhead the web are provided with outlet openings constituted by narrow slots or screen wall portion, and compressed air nozzles are arranged so as to cause fibres circulating in said flow crosswise to be moved crosswise in the flow outwardly through the outlet openings, whereby a high distributor capacity is obtained by simple means by forcing fibre material out of the outlet openings in a positive manner as distinguished from outlet by general suction from outside the outlet openings.
