Extrusion International USA 5-2019

PREVIEW 68 Extrusion International 5/2019 PET in the Beverage sector, one of the aspects to which Moretto customers are most “loyal” is the constant treat- ment of OTX which ensures a stable process and an im- provement in machine cycle times, in the order of half a second. The application of MOISTURE METER MANAGER inte- grates the dryer into a “responsive” system as required by the 4.0 intelligent factory project. MOISTURE METER MANAGER measures the initial moisture of the granule and based on this, knowing the precise behaviour of each material, it performs the appropriate drying cycle to obtain the result requested by the customer in terms of final mois- ture, which is then monitored at the hoppers outlet. To automatically manage and supervise the entire convey- ing process of small or large quantities of plastic material, ONE WIRE 3 guarantees the greatest transport efficiency, thanks to its advanced FIFO logic. ONEWIRE 3 also controls those devices, whichwith their exclusive technologies, con- tribute to optimizing the granule conveying and feeding process. In particular, the DOLPHIN manifold unit, auto- matically supplies and distributes all the materials to all the machines, avoiding any risk of contamination and human error. KRUISEKONTROL, an exclusive Moretto patent, which the European Patent Office (EPO) recognized as “the only automatic and intelligent system in the world capable of defining the best transport conditions for each plastic ma- terial”. The uniqueness of this system lies in its ability to manage the speed of the material during the conveying phases, eliminating the peaks and the consequent forma- tion of angel hair and wear of the pipes and adapt in a re- sponsive way the transport conditions, differently from the various inverter systems that simply act on the air speed, but without taking into account the numerous variables that characterize each material (KK controls more than 15 parameters) and which constitute elements of strong differentiation in their behaviour in the pipe. The DGM Gravix series dosing units are now a standard among customers who seek maximum precision in batch gravimetric dosing even in extreme use conditions. DGM Gravix is the dosing unit that, thanks to its particular con- trol with exclusive Vibration Immunity Systemand the dou- ble eyelid system, doses with precision up to 0.01% even when installed on a blow moulding machine, without be- ing affected by the continuous movements and vibrations to which it is subjected. The DGM Gravix dosing units cover dosing requirements for granule, powder and flakes materials, with dedicated applications, up to 12 materials and 12,000 kg/h. Applica- tions dedicated to micro dosing, such as Rotopulse, make these machines extremely flexible in their use in the de- partment. DPK is a compact precise loss-in-weight dosing system, suitable for the dosing of small amounts of masterbatch or additives. The technology of the load cells and the con- trol algorithm, make DPK reaching dosing accuracy of up to ± 0.03%. The masterbatch or additive to be dosed is contained in a hopper built in a specific transparent resis- tant acrylic material, free from electrostatic charges, which makes immediately visible the content material and the level of load and avoids the stop of material on the hopper walls. The hopper is easily removable without the use of tools and, together with the intelligent storage and recog- nition system of the masterbatches alongside the machine, the recipe change is even more immediate. For the supervision and control of plastics processing plants, Moretto has developed the advanced MOWIS 3 su- pervision system, a modular software capable of adapting to the needs and to the qualitative, productive and mana- gerial objectives of each customer, allowing connectivity
