MACHINERY [ Injection Moulding ]

The moulding system produces around 3000 containers per hour , labelled with IML technology
novelty will allow considerable energy savings compared to the standard Hybrid machine , which is also improved compared the solution with an inverter on the pump motor . The ‘ servopump ’ solution will allow considerable energy saving advantages , especially in the production of technical articles , where the moulding cycle is much longer , and will allow the pump to be completely switched off after charging the accumulator battery . The double servo-valve , indispensable for achieving high injection speeds , also offers more accurate management of the moulding gered , and then shut down the machine with a guided and safe procedure if necessary . Integration functions for any auxiliary equipment and the necessary connection to the company ‘ s MES for the transfer of production data and their processing are of course guaranteed .
RELIABILITY AND QUALITY All mechanical machining is carried out within BMB ‘ s plants and the production of raw steels comes exclusively from the Brescia foundries . These choices , as well as the production being concentrated solely in the Brescia site , are a
The 150 ml container weighing 10 g will be moulded with an hourly output of over 3600 pieces / hour
A Torque motor directly coupled to the plasticising screw with a dedicated profile , to enhance injection capacity ( g / s ), echoes the BMB philosophy used for the clamping unit , i . e . direct coupling with the screw , absence of belts and gearboxes to favour high performance , reliability and high plasticisation level with barrier screw and L / D ratio 27 . Hydraulic injection under accumulator is the beating heart of this machine , which , with only 60 mm screw diameter , is capable of injecting 3700 cm3 / s and reaching injection speeds of over 1000 mm / s , indispensable features of a packaging-focused machine . The solution of the classic three-phase asynchronous motor is abandoned in favour of the new servo-motor to drive the gear pump ; this
parameters , resulting in high constantly production .
NEW CONTROL SYSTEM The new SP250 controller , with its 21.5 inc . touch and functions that can be set through icons in a Windows environment that make it look more and more like a giant smart-phone , designed to offer great ease of use in a world where it is increasingly difficult to find expert technicians , represents a great support for any operator . For each parameter set , it is possible to create a minimum and a maximum value beyond which the machine will signal criticality , and it will be possible to indicate an alarm path , signalling and control whether or not the alarm is triggreat
guarantee of the traditional reliability and quality of the product . Borealis ‘ 100 per cent recycled material is in line with the processing regulations dictated by the European Community today , and last week ‘ s moulding trials were highly successful , perfectly aligned with the processing of virgin PP . The production standards are very high and able to meet the most refined requirements , both from the point of view of Muller automation , with side entry robot , a vision system and packaging in boxes of the moulded products , and from the decorative point of view , with the MCC label equipped with the ‘ HollyGrail 2.0 ’ system , capable of guide the product after use automatically through the supply chain for proper recycling .
