Smart Molding International 2-2020

42 smart_molding international 2/2020 periphery T he company manufactures its products in controlled sterile en - vironments up to class 7 clean - rooms and operates its injection moulding machines in conditions that meet very high cleanliness standards. This alone would be sufficient reason to consider the use of a near dust-free central material supply system a must. However, the fact that a central material supply system also prevents themateri - als, which are primarily supplied directly from the silos, aremixed up and the fact that the automated system is highly ef - ficient, are also important points for the company. When Heinlein built a new produc - tion hall for 20 injection moulding machines with clamping forces of between 250 and 2000 kilonewton, it drew on its extensive experience with the material supply system al - ready installed in its existing produc - tion hall when it came to selecting a material supply system. This hall con - tains a central material supply system manufactured by motan-colortronic that directly supplies 35 injection moulding machines with material from ten outdoor silos. Based on the company’s positive experience with this system and its low maintenance needs, Heinlein opted for yet another motan-colortronic system for taking care of all of the materials handling in the new production hall. The machines in its new hall are supplied with material – which pri - marily comprises polypropylene as well as HD and LD polyethylenes – from a total of twelve outdoor silos. All of these materials are 1 A pharma - ceutical grade certified materials. The old and new material supply systems are furthermore connected to each other, which makes for greater flex - ibility and security. This is because, if needed, the new and existing silos can be used for supplying both the new and the existing production halls. The system was also equipped with a loading station for bagged materials for processing small quantities, such as e.g. TPE or various special types of polypropylene. All of the system’s pipes – from those leading from the silos to the au - tomatic METROLINK distribution sta - tion to those leading to the machines – are made of stainless steel and meet Heinlein, a successful company based in the town of Ansbach in Franconia, Germany, produces a wide range of closures and dosing systems, some of which are patented and predominantly designed for the pharmaceutical and cosmetics industry. When it came to expanding its production facilities, Heinlein opted for a modern and efficient material supply system from motan.
