  • Patent number: 7247353
    Abstract: A method and a device for contactless application of a coating on a three dimensionally distributed surface (14;24;34;44;54;74;84;104). The method comprises application of electrically charged particles (15;25;35;55;65;75;85;105) in such positions on said surface as to form a predetermined pattern, by guiding each of said particles individually to a predetermined position on said surface. The guiding is made by means of an adjustable electric field (12;22;32;42;52;72;82;102) having flux lines with a longitudinal direction extending through said surface, whereby said particles form said coating according to said predetermined pattern on said surface.

  • Patent number: 6875393
    Abstract: A method for injection moulding, comprising introducing, under pressure, a melt into a cavity (14) defined by two mould halves (10, 11) of a mould (6). The method is characterized by the steps of joining the mould halves (10, 11), for definition of said cavity (14), by moving at least one of the mould halves (11) along a first axis, and, by moving along a second axis extending transversely of said first axis, arranging a locking means (7) on the mould (6). The locking means (7) has locking surfaces (19) which grasp the mould (6) and its joined mould halves (10, 11), at least one locking surface (19) wedgingly engaging a complementarily designed surface (17) of the mould (6) to cause conversion of the force by which the locking means (7) is arranged on the mould (6), into a locking force for holding together the mould halves (10, 11) in their joined state. The present invention also concerns an injection moulding assembly as well as a mould for injection moulding assemblies.

  • Patent number: 6872067
    Abstract: The invention relates to an injection mould (1) for producing three-dimensional components. The mould has a system (2) for mould tempering having at least one groove (12) which is arbitrarily extended between two points in the available volume of the mould for conducting a tempering medium which is intended for tempering of modules (4, 8) included in the mould (1). Each groove (12) is along essentially its entire extent covered by a cover (15). The invention also concerns such a system (2) for mould tempering of injection moulds (1), as well as an injection moulding assembly comprising such an injection mould (1).

  • Patent number: 6863853
    Abstract: An assembly for manufacturing carriers of information or decoration, characterised by a mould unit comprising two mould means which are joinable with each other. The mould unit comprises an injection moulding station for injection moulding of said carriers, and a printing station with a stamping unit for applying to said carrier a covering formed in accordance with the current information or decoration. The present invention also concerns a corresponding method.

  • Patent number: 6796016
    Abstract: An injection mould which comprises at least five modules aligned with each other. The five modules correspond to a first mould module and a second mould module to form a product cavity, a drive module for driving of sliders, an engaging module adapted, by application of a force, to prevent dividing between the first and the second mould module when introducing product material into the product cavity, and an ejector module for ejecting a completed product from one of the first and the second mould module. The method for making injection moulds comprises the steps of receiving a product pattern, defining function holes and function recesses, and defining, separate from and parallel to the construction of function holes and function recesses, a product cavity and the parting plane of the mould. Moreover the method comprises the step of mechanically machining a plurality of modules essentially simultaneously.

  • Patent number: 6659761
    Abstract: A slider mechanism (1) for an injection mould comprising a core (5) which is insertable into a cavity (20) defined by mould halves (12) of the mould. The slider mechanism (1) has a body (2) which supports the core (5). The invention is characterised by a drive device (3), and a connection (4) between said body (2) and said drive device (3). The connection (4) is adapted to convert a rotary motion of the drive device (3) into a translational motion of the body (2). The invention also concerns an injection mould comprising such a slider mechanism as well as the actual slider.

  • Patent number: 6652263
    Abstract: A mold includes a first and a second mutually joinable mold half which in their joined state define at least one cavity, and a sprue formed in the mold for conducting a melt to each cavity. The sprue includes an ingate portion connecting to each cavity and contained in a first ejector of an ejector arrangement. An injection molding assembly including such a mold is also disclosed.
