claimed to never stop the conveying system – not even for regular maintenance. In addition, the new Visibus system can be completely managed by the Halo control to guarantee a trouble-free fully automated conveying process. The new single station three phase blower Solo includes a new fabric filter with automatic filter cleaning. Wittmann Group has developed a number of new initiatives for materials handling in injection moulding. The M7 control for central material conveying systems can be used universally and is ideally suited for practically all requirements for the preparation and supply of plastic granulate. In addition to the fixed displays and input options of the M7 network control, the control also offers a VNC server option. With the VNC option, the user gets a quick overview of the individual components without having to visit the production site directly. It is also available for retrofitting. The company has also developed the HiQ-Flow process control to deter- mine precisely any devia- tion from the material’s nominal value and corrects it in real time. The basis for this process control is the recording of a high number of measurement points along the injection stroke. This results in time and cost savings, a more stable process and also helps to save energy. The swivelling hopper adapter developed for
Wittmann conveyors ensures easy cleaning due to its flexible swivel mechanism. The hopper guaran- tees fast and easy handling, because the laborious handling and removal of conveyors and material hoses is completely eliminated. The conveyor is simply swivelled to the side, cleaned, brought back into position and the machine is then ready for use again. This is also available for retrofitting. Gravimetric dosing units have a local material
and recipe memory. These recipes can be easily transferred between several dosing units via a PC solution from Wittmann, called GraviLog. In addition, GraviLog can remotely control all these connected devices and also document their data graphically and in tabular form. Moretto has introduced the DPK continuous loss-in-weight colour feeder, which is suitable for injection moulding applications. The DPK dosing unit is a compact, precision feeder, suitable for

dosing small quantities of colour or additives into a flow of base material. The masterbatch or additive to be dosed is contained in a hopper made of a specific transparent, shock-resistant acrylic material that makes the material contained and the level of the load immediately visible. The hopper is easily removed without tools for replenishment or additive change. The company says that the precision of this machine is guaranteed, even at low rates. The load cell technology and control algorithm make DPK immune to vibrations, achieving higher dosage precision without risk of overdosing the additive or masterbatch. The control of this dosing unit is supplied with a simple and intuitive touch screen interface, where it is possible to store and recall product recipes. DPK has ethernet, RS485 connec- tions and is arranged for MOWIS. Brabender Technologie has developed a feeder specially designed to tackle recycled materials. The company says that shred- ded carbon and natural fibres can form into uneven flakes and fibres that snag mechanically on product bridges and do not reach
feed screws. The FiberXpert FX50 has been specifically developed for feeding recycled materials like carbon and natural fibres, recycled PP, PET and bottle flakes, shredded plastic and other fibre products like cellulose, acrylic, aramid, PPS, polyamide, polymer or polyester fibres. Long, unevenly cut and non-flow-capable fibres can be fed reliably with the aid of a special fibre screw, hopper design with large inflow cross-section, large, steep-walled hopper and special agitator geometry and positioning.
