  • Publication number: 20210008773
    Abstract: Method for injection moulding one or more parts using an injection moulding machine and tool (12, 13) comprising at least one mould cavity (17), and a feed system comprising at least one gate (18) and at least one runner (19, 20, 21) that is located upstream of the at least one gate (18). The at least one runner (19, 20, 21) comprises a at least one moveable wall and the method comprises the step of changing at least one cross-sectional dimension (T, B, H, S or S+?S) of the at least one runner (19, 20, 21) by moving the at least one moveable wall in order achieve at least one of the following: a) to vary a flow rate of material in the at least one runner (19, 20, 21), b) to apply a holding pressure to material in the at least one runner (19, 20, 21) and consequently to the at least one mould cavity (17), c) to compress residue in the at least one runner (19, 20, 21).

  • Patent number: 8507108
    Abstract: The present invention relates to a cutting tool insert, solid end mill, or drill, comprising a substrate and a coating. The coating is composed of one or more layers of refractory compounds of which at least one layer comprises a h-Me1Me2X phase, where Me1 is one or several of the elements V, Cr, Nb, and Ta and Me2 is one or several of the elements Ti, Zr, Hf, Al, and Si and X is one or several of the elements N, C, O or B. The ratio R=(at-% X)/(at-% Me1+at-% Me2) of the h-MelMe2X phase is between 0.5 and 1.0, preferably between 0.8 and 1.0 and X contains less than 30 at-% of O+B. This invention is particularly useful in metal cutting applications where the chip thickness is small and the work material is hard e.g. copy milling using solid end mills, insert milling cutters or drilling of hardened steels.

  • Patent number: 7093848
    Abstract: The present invention relates to a motor vehicle occupant impact protection arrangement. The motor vehicle occupant impact protection arrangement comprises an airbag device within a housing, an airbag device launch trigger, triggering the launching of the airbag device upon a motor vehicle impact, and a sheathing, such as a dashboard in an occupant compartment of the motor vehicle, to which the housing is connected, and behind which, in relation to the occupant, the airbag device is located. The sheathing is having a mouth through which the airbag device, guided by the housing, is launched into the occupant compartment. The sheathing, after the launch of the airbag device, is adapted to essentially return to original state and to essentially close the mouth.
