Wittmann Battenfeld GmbH showed 17 injection presses, robots and pieces of auxiliary equipment at its Competence Days April 24-25 in Kottingbrunn, Austria — marked by the first-ever showing of the new MacroPower E Hybrid press.

The large-tonnage, two-platen MacroPower E Hybrid combines an all-electric injection unit with servo-hydraulic drive for the clamping and nozzle movements.

The hydraulic pump is an electrically adjustable axial piston pump with a variable displacement volume. It responds to the demand of the clamping unit, as the delivery is controlled by the motor speed and the pivoting angle of the hydraulic pump. That way, the optimal relationship between the pump’s efficiency and the motor speed gets calculated for every operating point — saving energy.

The press boasts injection speeds of up to 450 millimeters per second.

Wittmann Battenfeld also molded a hockey stick on an HM 300 press using the Airmould gas-assisted injection molding process. Other presses showed multicomponent molding of Playmobil figures, liquid silicone molding of a medical part.

In auxiliary news, the machinery maker introduced an option that allows you to clean its Gravimax B14 gravimetric blender, without the need for any tools. A special elevating mechanism means that loaders already mounted on the blender do not have to be demounted now. Two pneumatic cylinders lift the complete covering of the material hoppers, including the loaders. Then the hoppers can be cleaned at their current position, or removed, cleaned and reinserted.
