A method of forming a bi-injected closure, comprising the steps of: forming a cap with a top plate and a depending sidewall, in a first injection moulding phase using a first mould part, the cap formed so as to include one or more external sealing areas; changing the first mould part for a second mould part, the second mould part sealing against the or each sealing area on the cap; and forming an outer ring around the cap sidewall whilst the second mould part is sealed against the sealing area/s in a second moulding phase.

A line for the continuous cycle production of plastic objects comprises: an extruder configured to deliver a flow of plastic fluid; a compression moulding machine including a rotating moulding carousel and a plurality of moulds to form an ordered succession of objects from corresponding doses; a transfer apparatus configured to feed the doses individually to the compression moulding machine; a conveyor; a first sensor configured to detect a first diagnostic signal; a control unit programmed to capture the first diagnostic signal.

An in-mold lid closing apparatus includes a lid engagement member, a first actuation assembly connected to a first portion of the lid engagement member, a second actuation assembly connected to a second opposing portion of the lid engagement member, and a controller disposed in electrical communication with the first actuation assembly and the second actuation assembly. The controller is configured to transmit a first drive signal to the first actuation assembly and a second drive signal to the second actuation assembly to drive one of a linear position and a rotational position of the lid engagement member and to adjust at least one of the first drive signal and the second drive signal based upon a first feedback signal received from the first actuation assembly and a second feedback signal received from the second actuation assembly.

The invention provides a process for the preparation of a multimodal high density polyethylene (HDPE) having a melt flow rate (MFR.sub.2) of 0.1 to 4.0 g/10 min, said process comprising: (i) polymerising ethylene in a first polymerisation stage in the presence of a Ziegler-Natta catalyst to prepare a first ethylene homopolymer having a MFR.sub.2 from 10 to 500 g/10 min; (ii) polymerising ethylene in a second polymerisation stage in the presence of said catalyst and said first ethylene homopolymer to prepare an ethylene homopolymer mixture comprising said first ethylene homopolymer and a second ethylene homopolymer, said mixture having a MFR.sub.2 from 50 to 1000 g/10 min; and (iii) polymerising ethylene and at least one alpha-olefin comonomer in a third polymerisation stage in the presence of said catalyst and said ethylene homopolymer mixture to prepare said multimodal HDPE.

A device for forming components having a cavity comprises a core extending along a center axis and configured to fit into the cavity to machine the component with a forming process, the core is configured to be pulled out of the cavity after machining; the core comprises segments in mutually parallel arrangement, which are adapted to be alternated between a machining configuration and an extraction configuration, the segments are locked together in the machining configuration to prepare the core to machining, the segments are able to slide relative to each other in the extraction configuration, to reduce the diameter of the core and pull it out of the cavity; the device further comprises drive means of the segments to move them at least from the machining configuration to the extraction configuration.

A method and an apparatus form aluminium screw capsules with a safety ring made of synthetic plastics for tamperproof closing of containers. An aluminium capsule body is inserted into a moulding cavity of a mould conformed and arranged for the overmoulding of a safety ring on an edge of an annular wall of the capsule body. An annular sealing zone is defined for the synthetic plastic material between a first surface of the capsule body and a mould first portion inserted into the central cavity of the capsule body to form a safety ring anchored to the capsule body.

A composite article assembly arrangement includes mechanized assembly station tooling for supporting certain composite article assembly methodologies with a view toward a preferred lid assembly application. First assembly station tooling 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 mechanized assembly station tooling, which 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. Alternative assembly station tooling operates to direct first composite elements into assembled relation with stationary second composite elements for forming basic composites to which successive composite elements are similarly added.

A closure is configured to mount on a container to close an open mouth formed in the container. The closure includes a lid and an outer layer coupled to the lid.

A tool for manufacturing a cap for a container comprises a blade set that includes a plurality of knives. The knives are configured to make incisions in a cap having a main body having a top plate and a circular sidewall. The top plate has a top surface, wherein two opposite sides of the circular sidewall circularly connect to each other, one periphery of the circular sidewall connects to one surface of the top plate forming a closed end, and the other periphery of the circular sidewall at the opposite side of the closed end forms an opened end and a ring member, which is located at the opened end of the main body. There is a first tab on the ring member and a second tab on the sidewall.

The present invention relates to a molded article with a metallic appearance and a process for making the same. Particularly, the present invention relates to a molded article having a part that comprises a layer with a sandwich structure.
