An apparatus for producing an object from a polymeric material having a melting temperature comprises: a melting device for melting the polymeric material, a heat exchanger for cooling the polymeric material melted by the melting device below the melting temperature, a mould arranged downstream of the heat exchanger for forming the object from the polymeric material, while the polymeric material has a temperature lower than said melting temperature, a heat recovery device associated with the heat exchanger, the heat recovery device being configured to recover at least part of the heat released by the polymeric material to the heat exchanger.

One Piece Oversize Tab Closure

A one piece oversize tab closure and process for manufacturing thereof is described. The tab trim process includes punching, cutting, pre-positioning the plastic with cylinder or mechanical rocking levers, or using heating to flex the plastic for trimming and repositioning the tab. By heating or flattening the tab or window, the size of the tab is larger relative to the size of the window of the closure.

Pourer and manufacturing method for same

A pourer includes a pour spout, wherein the pour spout is configured to serve as a spout for a content liquid stored in a container main body, and is configured to be attached to a mouth part of the container main body, wherein the pour spout includes a surplus resin part provided on a part of a top surface of the pour spout through which the content liquid passes, and wherein the surplus resin part protrudes outwardly in the radial direction from an outer peripheral edge of the top surface of the pour spout.

PROCESS OF FORMING POLYMERIC MATERIAL

A method for forming an article includes providing a sheet of material, optionally conditioning the sheet with a surface of a roller, forming the sheet to provide a web, and separating an article from the web to provide the article. An apparatus adapted to form the article from a sheet is provided.

Composite article assembly system and method
10710293 · 2020-07-14 ·

A composite article assembly arrangement includes an all-in-one assembly station for supporting certain two-workpiece or composite article assembly methodologies with a view toward a preferred lid assembly application. The all-in-one assembly station includes a stationary main base plate, opposed intermediate compactor plates, and opposed outer plates, which compactor plates and outer plates are movable relative to the stationary main base plate. One or more continuous webs bearing thermoformed first and second workpieces are directed through the assembly station, which assembly station operates to both separate the first and second workpieces from the web(s) as directed therethrough and assemble the first and second workpieces in one clapping movement of the compactor plates and outer plates relative to the main base plate. The main base plate comprises an axial alignment chamber or cavity that operates to mechanically or structurally maintain axial alignment of the first and second workpieces during workpiece assembly.

Apparatus for molding hollow workpieces

An apparatus and process for molding workpieces usable for consumer products. The workpieces may be injection molded with a cavity formed by a core pin and have an undercut, such as internal threads, in the cavity. The apparatus has a drive system with a stripper plate mounted for alternatingly forward and retracting axial movement. The stripper plate is axially driven and drives a stripper sleeve barrel cam and a core pin base barrel cam, each having respective cam followers. The respective motions of the cam followers are superimposed on a stripper sleeve insert, which drives a core pin sleeve. The core pin sleeve is subjected to responsive three dimensional motion, allowing an internally threaded workpiece to be unscrewed from the core pin sleeve. The system does not require separate drives for the core pin sleeve, a single stripper plate drive being sufficient.
