The first plate comprises one or more projections (120, 122) surrounding the mold space, and the second plate is adapted to be superimposed on the first plate such that it primarily contacts the one or more projections of the first plate.

The present disclosure relates to a tool such as an injection moulding tool or an embossing tool. A heating device including a stack of layers is provided for heating a tool surface. The stack may include a coil carrier layer with a number of wound coils for generating a magnetic field, and a conductive top layer, being adjacent to the tool surface currents are induced in the top layer to heat the surface. Efficient heating may be provided by solutions involving low resistivity layers that lead currents to the top layer without themselves developing heat to any greater extent. A conduction frame device can be provided beneath the top layer and around the perimeter thereof to provide reliable contact with a backing layer.

The present disclosure provides a container. In an embodiment, a flexible container (8) is provided and includes a first multilayer film (16) and a second multilayer film (18). Each multilayer film includes a seal layer. The multilayer films are arranged such that seal layers oppose each other and the second multilayer film is superimposed on the first multilayer film. The films are sealed along a common peripheral edge (20). The flexible container includes a fitment (10) having a base (12). The base (12) includes an ethylene/a-olefin multi-block copolymer. The flexible container includes a fitment seal (22) comprising the base located between the multilayer films. The base is sealed to each multilayer film at a portion of the common peripheral edge (20).

A machine including a mold which delimits an overmolding cavity, for receiving a hollow portion of a bi-material part, cooling means along the overmolding cavity, a core positionable inside the hollow portion and containing heating means for bringing the core to a heating temperature higher than 150 C., and an injector injecting an overmolding material, formed by the core and the hollow portion, for forming an inner portion of the bi-material part. In order to obtain the overmolded inner portion even if the hollow portion has poor heat resistance, the cooling means maintain the overmolding cavity at a cooling temperature lower than 110 C. while the core is brought to the heating temperature, while the overmolding material has been injected by the injector into the overmolding cavity.

A method for reinforcing joints between one or more components is presented. Adhesive is applied to joint areas of contact between the components and the components are stitched together at the joint areas to ensure that the joints are mechanically stable enough to withstand stresses such as pressurization and external manipulation.

A method of fusing without contact the ends of thermoplastic filaments grouped together to form at least two tufts. The method steps include providing at least two tufts of thermoplastic filaments arranged at a distance to each other, providing a heating plate at least partly made from a conductive material and structured to have at least two heating sectors separated from one another by at least one separation sector arranged for emitting at least less thermal radiation then the heating sectors, each of the heating sectors having conductive material and a heating surface corresponding in shape and position to the shape and position of the ends of the tufts, exposing the ends of the tufts to the heating plate such that the tuft ends and the heating sectors are aligned with each other, and generating an electric-current flow through the heating sectors so that the heating surfaces of the heating sectors emit thermal radiation that is absorbed by the ends of the filaments, whereby the ends of the filaments melt and the filaments of each tuft are fused together.
