Partnership: motan-colortronic is showcasing on the KrausMaffei stand
Live demonstration of the pilot project Industry 4.0
motan-colortronic and KraussMaffei present a specific example of use for intelligent communication between machines. With the development of a UPC-UA-interface, motan-colortronic is the first periphery supplier capable of communicating with the processing machines regardless of manufacturer and platform. The software used is an open international IT-standard which has already been used many times in machine manufacturing and carries the approval of the European trade associations for the plastics industry.
With this project motan, together with KraussMaffei, has put the complete networking of the injection moulding unit with the material supply to the test. For example, the drying process automatically adapts to the planned start-up of the machine at production start. Inversely, a purposeful emptying of the drying bin can be planned at the end of production. The required time for emptying is calculated according to the planned rest production and implemented. This not only saves unnecessary energy for drying and conveying, but also minimises material returned and prevents material loss. The availability of material of the processing machine is monitored through specific information exchange even during the manufacturing process. Through the permanent balancing of quantity and remaining production time the system has command of all relevant information. Conveying problems are shown centrally at the machine, enabling quick reaction. Therefore, material shortages can be prevented and efficiency can be increased. An intuitive operational concept provides the customer with a high degree of transparency and overview.
These and other results from practical examples of use of the intelligent communication followed and by visitors at the KraussMaffei stand with a live demonstration. With specifically chosen scenarios visitors can also learn how to increase efficiency through data exchange or even reduce energy consumption to a minimum.
Contact persons are available for all interested parties both at the motan-colortronic and the KraussMaffei stands.
Precise dosing of the fibre amount with loss-in-weight technology
Highly concentrated PP-long fibre granulates are difficult to dose and convey due to their consistency and complex flow properties and therefore require a specific Materials Management concept. As a result of
motan-colortronic’s many years of experience not only in injection moulding, but also in extrusion and compounding, an accurate dosing solution for highly concentrated long fibre could be found. It’s based on the first time use of a special loss-in-weight dosing unit in an injection moulding process. The C-Flex M dosing units with massage rollers in this form have previously only been used in extrusion and compounding. The C-Flex M dosing unit with its dosing auger and the steep polyether walls that are activated sideways by massage rollers guaranties an excellent and even filling of the dosing screw and therefore high dosing performance and accuracy. In addition, rod material is activated particularly well and bridge building is reliably prevented.
Visitors can view this state-of-the-art application on an injection moulding unit at the KraussMaffei stand: A highly concentrated PP-long fibre granulate with a fibre content of 60% and a thinner polymer (PP) is dosed in equal parts via two dosing units to the plasticising screw and processed. Through the use of the C-Flex M dosing unit with massage rollers, a constant material flow is guaranteed for the first time. “Fluctuations regarding the adjustment of the fibre content can be significantly reduced compared to conventional mixing concepts. According to current measurements they correspond to the load fluctuation of the manufacturer“, says Jochen Mitzler, manager of Strategic Product Management at KrausMaffei. KraussMaffei also adds that processors can now adjust the process more precisely than previously possible. These advantages are particularly beneficial when producing safety related components, where constant and reproducible processes are required.
