In order to determine the contents of solids in a heated elongated slug of thixotropic metal having a longitudinal axis, there is an apparatus comprising an inductive heating coil with electrical winding. Moreover, a sensor includes at least one measuring coil arranged between the heating coil and the slug. This sensor provides an output signal which corresponds to the contents of solids demanded.

Apparatus for determining the solid contents of a slug by induction

An injection unit for an injection molding or die-casting machine comprises an injection ram which injects molten material out of an injection sleeve into a mold or die during a filling phase. This injection ram is connected to a drive piston which is movable within a drive cylinder for actuating the injection ram. The whole ram unit, comprising the injection ram and the drive piston, consists of at least two parts releasably connected together. A control device for the movement of the injection ram during the different phases of injection comprises a control valve. A signal transfer arrangement is interconnected between this control valve and the ram unit which is provided with a damping arrangement so that its releasably connected parts are movable relative to each other.
