    摘要： A multi-cavity mould (1) comprising:—an upper tool (11) and a lower tool (12) arranged in a cooperating manner; characterized in that the upper tool (11) comprises a knife pressure box (13) comprising:—a horizontal top plate (131);—first and second end plates (132) and first and second side plates (133) extending orthogonally downwardly from a lower surface of the plate (131); the plates (132, 133) are connected such that the plate (131) and the plates (132, 133) form a downwardly open rectangular parallelepiped enclosure; the plates (132, 133) are made from tool steel with a thickness (t) from 6.35-10 mm and a cutting surface (130) defined along an orthogonally downwardly projecting end of plates (132, 133) wherein—the surface (130) has a substantially V-shaped profile comprising a micro flat face (M) with a width from 0.02-0.1 mm and is positioned such that when the pressure box (13) is pressed against the sheet (3), the surface (130) partially penetrates the sheet (3) in order to form a seal around the pressure box (13) by pressing a zone of the sheet (3) which was partially trimmed and situated inside the enclosure against the surface (130).

    摘要： An article useful as a forming and cutting tool for molding composite material and cutting non-planar edges of molded composite material. The article includes an upper and lower die. The upper die includes an upper pressure pad with an upper shearing edge and an upper mold with a cavity. The lower die includes a lower pressure pad and a lower mold with a core and a lower shearing edge. The upper die is adapted to come into contact with the lower die so that the upper pressure pad and upper mold apply pressure to the lower pressure pad and lower mold to form a composite material blank into a formed composite structure. The upper die is adapted to contact the lower die so that the upper shearing edge bypasses the lower shearing edge to form a non-planar cut in at least a portion of a formed composite.

    摘要： Methods and apparatuses for cutting thin film solar cells are provided. According to various implementations, the methods involve cutting a substrate having thin film solar cell materials deposited thereon by inducing a tear along the cutting line. Simultaneously with the tearing, the torn edges may be plastically deformed to produce a desired torn edge cross-sectional profile. Such a fracture may be induced by clamping regions of the substrate while simultaneously displacing the clamped regions relative to each other through the thickness of the substrate as the substrate is fed through the clamps providing the clamping. Apparatuses for cutting are also provided. According to various implementations, the apparatus may have cutter rollers and support rollers configured with an adjustable radial overlap.

    摘要： The invention relates to a hot forming tool for hot forming a metal workpiece, having at least two dies which may be moved relative to one another for forming the workpiece, and having a cooling device by means of which the workpiece may be cooled in the hot forming tool from a first, higher temperature to a second, lower temperature. To improve the hot forming tool, it is provided that the hot forming tool is equipped with a separating device by means of which a separating operation may be carried out on a workpiece present in the hot forming tool. The invention further relates to a method for hot forming.

    摘要： The present invention relates to a thermoforming device for thermoforming a product (1) from a plastic foil (23), and to a corresponding method. The invention relates particularly to a thermoforming process and device in which a slot (2) is arranged in a product (1) to be formed. The invention also relates to a product (1), particularly a flowerpot, manufactured using this thermoforming device or method. The thermoforming device is characterized in that the cutting sleeve (10) and cutting plate (7) and/or hold-down element (8) define an auxiliary cutting line through which the plastic foil (23) is cut in order to arrange a slot (2) in the product (1) to be formed. The functions of slot-forming and product-foil separation are hereby performed by substantially the same components.
