avoids heat loss by creating process consistency. Krystal maintenance hoppers (TMK) are made of transpar- ent shock-proof acrylic material, ensuring effective containment of plastic granules, while offering good visibility to allow the operator to immediately verify material levels. Moretto’s Efficiency 4.0 initiative is designed to manage the entire plastics preparation process, from storage in the silos to injection moulding machine. The range includes technologies and machines developed to guarantee adequate levels of dehumidification, granulation and dosage of the polymer. Mowis 3 is an integrated self-configurable supervision system with intuitive object program- ming, developed by Moretto for connection and control of the whole automation chain in plastics processing plants. The company says that Mowis 3 is modular software with an auto-configurable and user friendly interface which allows immediate display of the system status. It allows the process to be controlled from any location, on-site or remote. Based on the SCADA system, Mowis 3 allows safe and immediate exchange of data between stand- ard and tailor-made modules and the customer management system. Motan-Colortronic has adapted its mixer module MB 2l with dosing unit Miniblend V combination for use with additional systems. The company adds that mechanical forced mixing is the best technology to homogenise powder additives, masterbatch, virgin material and regrind. The MC 2l can now be used in combination with the dosing and mixing Minicolor series and the unit can also be used with other system technol- ogy and applications. Different connection, installation and protection options enable flexible use. The unit can be installed directly under the dosing unit on the machine or it is also possible to combine it with material loaders and proportioning valves as well as small drying bins. No matter how it is in- stalled, the casing and mixing module remains easy to clean. The unit is operated with the Volu MC control which is available as a separate module. It reliably adjusts the mixer revolutions according to the defined set-point value for different materials and blends. Motan-Colortronic has also expanded its univer- sal material flow and selection system. The Metrolink

now has additional modules and one additional size. The company says that central material supply using fixed piping has significant logistical and quality-relevant advantages over material supply to each individual machine. This is because much less space is needed for production and there is no need for costly forklift transporta- tion. There is no material loss and the production area typically remains much cleaner. If the system is designed correctly, the entire material flow can be documented. As the centre of the
material supply system,
Metrolink can connect 16 material feedlines with 2-32 machines. The modular design of the station makes it possible to expand the system easily at a later date. In addition to the established 45 mm and 60 mm pipe diameter systems, there is now also a 50 mm version. Due to fine tuning of all versions, vacuum loss has been eliminated. As a result, energy consumption has been reduced and performance has increased, says the company. The use of granules with increased percentages
of glass fibre or certain recycled material can result in increased wear of the pipes. As an alternative to standard stainless-steel pipes, Motan-Colortronic says that it now also offers pipe bends made from wear resistant, PU coated glass. These bends are
