43 www.smart-molding.com Heinlein’s high hygiene requirements. They were installed on predefined sections along the hall’s walls specifi - cally designed and built to support the entire supply infrastructure such as power lines, compressed air pipes as well as cooling water supply and return pipes. The entire system revolves around the METROLINK – the distribution sta - tion, which, once set up, automatically and without any risk of contamination connects all of the relevant material supply system pipes with those of the relevant machines to be supplied. This means that there is zero risk that a machine could be supplied with the wrong material. The material supply system chosen by Heinlein takes up very little space and has 2x10 material supply lines and 2x10 outgoing lines leading to the machines. In contrast to other distribution stations, there is no need for switching any connections or emptying operations during conveying thanks to the permanent pre-defined material allocations in the METROLINK system. Heinlein also turned to motan-col - ortronic to meet its dosing needs and fitted its machines with volumetric MINIBLEND V disc dosing devices and METRO G conveying hoppers with de- dusting modules as the final items on the material conveying lines. These de - vices are of various sizes in line with the relevant throughput volumes. The system’s two-component valves can be used to simply feed back any regrind material into the production process. The MINIBLEND V devices release the additives and colours into the base materials at the same time as they are drawn into the injection moulding machines. This means that there is no need for a mixer. The company has also ensured that there is capacity for future expansion: The entire material supply system can easily be expanded to supply 40 injec - tion moulding machines. motan-colortronic www.motan-colortronic.com periphery The METROLINK distribution station comprises two units that are able to automatically link ten incoming lines to ten outgoing lines respectively. The system has been designed in such a way that it can easily be expanded at any time. (Image: motan-colortronic) The de-dusting modules enable the use of regrind without loss of quality. The dust is automatically separated into the central filter in a separate room.
