CellForm technology for foamed ASA/PC parts

  • CellForm/MuCell technology: material savings of 35%
  • Produced part: 127 g ASA/PC at 37 seconds cycle time

KraussMaffei will be presenting its all-electric AX series of injection moulding machines featuring CellForm technology for physical foaming live at the FIP Fair in Lyon, France. The CellForm technology can be used to save both energy and materials without compromising on component quality.

KraussMaffei will be presenting an AX 130-750 CellForm with integrated linear robot LRX 50 and equipped with the new MuCell system for producing foamed components. The machine produces an ASA/PC copolymer cover for white goods (such as washing machines) at a shot weight of 127 g in a cycle time of around 37 seconds. By adapting the part design especially to MuCell, the wall thicknesses and part weight were adjusted in such a way that material savings of 35 percent could be achieved with no loss of functionality.

Due to the high precision and shot weight constancy, the all-electric AX series injection moulding machine is predestined for the CellForm process as there is no need for an offsetting holding pressure phase. A special feature of the machine: active functions that are required for the foaming process, such as back pressure, can also be executed with opened safety gates by means of electric motor drives and in compliance with current safety standards. All parameters in the MuCell process are visualized on the MC6 control system.
