The transfer occurs through axial forward movement on the ejector end, rotation through 180 degrees, and return to the ejector end. It is thus possible to modify the contours of the moulding for the second component both, on the stationary platen and on the mobile platen (see the finished part detail below). The axial movements are generated by the ejector on the machine end. The rotation is generated by a hydraulic motor or an electric motor as a component on the injection moulding machine or as component part of the mould.
Short cycle times, and
as compared to the dial, shorter tie bar distances are required in most instances.
