fore also has a „ Wide Platen “ version . BMB then developed its own control system , which includes a new CPU for greater digitalisation and an interface with a larger screen . The new CNC control system , with a 21 “ touch screen , also offers passwords of different levels , recognisable through RFID reader , to allow more or less deep programming of the machine . From September , all this will be the standard on BMB machines . The system is an evolution of the previous one , so the user can smoothly transfer programs from an existing press to a new one . For example , the operator engaged in the programming of a specific function , such as setting the temperatures of the barrel or activating only some selected radials , will be constantly supported by an online help |
function , with instructions that can be consulted in all the languages of the user ’ s and maintenance manual , on the exact page concerning the activity being programmed , automatically selected by the machine control system . The control system also includes intelligent features that help the operator obtain the best product quality at the most appropriate performance levels . Each parameter is constantly controlled automatically and generates an alarm or pre-alarm when its value exceeds the set limits one or more consecutive times or in a certain number of cycles , for reasons related to unforeseen factors . Today it is imperative to use recycled materials , for example , whose properties may vary over time ; thanks to the Torque motor of the plasticising unit , |
for example , it is possible to correct the rotation speed and always obtain the grams per second as desired without having to intervene manually with temporary adjustments , often by trial and error and without the possibility of tracking . Of course , everything can be transferred to the corporate MES system along with the trend of all the parameters reported in excel files , interesting for tracking purposes , or rather , for implementing production strategies aimed at reducing consumption or taking wide-ranging decisions and production optimisation measures . But , above all , great efforts are continuously dedicated to the optimisation of the energy efficiency of injection moulding processes , with the aim of cutting the cost per kilogram of material processed . In fact , this is the main focus of current investments |
