PLAST 2023 | SHOW PREVIEW
The performance of Engel’s iQ smart assistant systems will be demonstrated in a production cell based on an all-electric Engel E-mac 265/80 injection moulding machine with a clamping force of 80 tonnes. The cell is equipped with a four-cavity mould for the production of PBT automotive connec-
CMG Granulators says its new SL series is a range of low speed screen-less granulators for injection moulders which have unique attributes, leading to the highest degree of regrind quality, efficiency of operation, ease of cleaning and the best applica- tion flexibility. The range consists of four models, for capacities going from 5 kg/h up to 30 kg/h. SL granulators are designed to produce the most homogeneous regrind shape and dimen- sions, without any dust. The rotor cutters perform a fine and precise cut of the parts to regrind and do not fracture or crush them as conventional screen- less granulators do. The sector grinding elements are available in three different sizes, to obtain the most adequate regrind size for the injection process. CMG says the great advantage of dimen- sionally adequate regrind is most appreciated when the SL granulator is coupled with small tonnage injection moulding machines. At Plast 2023, CMG will also present the EV916 and EV616 models from its Evoluzione series, suitable for the most critical operating conditions, for wet or dry granulation, with granulation capacity from 2,000 to over 5,000 kg/h. CMG is introducing a brand new cutting chamber design for its Evoluzi- one granulators. The new rotor configuration allows the rotor blades to cut the plastic feedstock perpen- dicularly against the bed blades, obtaining the highest degree of cutting penetration and precision. Other products on show at CMG’s stand include
granulators from: its new G26 line, which features integral sound enclosure and an innovative feed hopper design to accommodate the widest variety of shapes and dimensions for the parts to grind; and the G17 series for small regrind. �

tors. An Engel Viper linear robot in the new size 4 will remove the components from the mould and place them on the conveyor belt. The company says the all-electric drives of the E-mac machine contribute to a high degree of energy efficiency, further enhanced by the E-flomo and E-temp temperature control technology integrated with the smart iQ Flow control assistant system, which saves 4,000 kWh in one year of operation at full capacity. The E-flomo temperature- control water manifold system monitors and regulates the flow rate, pressure, temperature and temperature differences. Based on these param- eters, iQ Flow control assistance actively regulates the temperature difference in the individual circuits. This means that the thermal conditions in the mould remain constant at all times, even if there are fluctuations in the system. Engel highlights moulding with recycled material in an application developed in collaboration with Alpla Group, Brink and IPB Printing. This allows post-consumer rPET containers (in this case, a round 125 ml thin wall container) to be produced in a single injection moulding process step, without the need to use preforms. The production cell features an Engel E-speed 280/50 injection moulding machine, a hybrid machine with electrical clamping unit and hydraulic injection unit for the high perfor- mance requirements of thin-wall injection moulding. In another demonstration, a fully automated
production cell produces 7 mm blade valves made of LSR, used in a very wide range of applications in cars, medical technology and packaging. Engel says what all of these applications have in common is the very strict process consistency requirements in terms of injection moulding production. The cell combines an E-victory machine and
smart digital assistance using mould and plasticis- ing technology from Nexus. Production is fully automated in a 64-cavity mould with an Engel Easix articulated robot and an integrated vision control system. �
