At Plastpol, a GX 400-3000 will produce a typical automotive interior part from physical foam (MuCell) using CellForm technology. The entire production cell will demonstrate maximum productivity and innovative detail solutions for zero defect production and production intelligence. "In combination with an MuCell equipment package and a precision injection and plasticizing unit, the GX series is tailor-made for reliable production of foamed components," explains Frank Peters, Vice President Sales at KraussMaffei. "This automotive application shows the enormous potential still available in lightweight thermoplastic solutions," Peters adds. The high shot weight constancy of less than +/- 0.1 percent ensures reliable production even under the most demanding conditions. This means that productivity is assured. As the fastest dual platen machine on the market, the GX offers the shortest movement times and maximum productivity. The smooth-running mechanism reduces traction resistance by up to 80 percent and, together with a hydraulic concept designed for minimum flow losses, ensures maximum energy efficiency.
Parts are made automatically in a fully integrated production cell with a LRX 250 linear robot that is fitted with the handheld pendant of the new MC6 control system. "The robot is fully integrated - not only in terms of the control unit but also mechanically. Detailed coordination of the GX and the robot produces a seamless production cell," Peters stresses. Innovative machine vision facilitates zero defect production thanks to in-line quality testing in combination with part weight testing. These quality parameters are stored and documented in the MC6 control system with the target and actual values for each injection molding cycle.
Machine operators are also assisted by visual aids. Workspace monitoring by means of a camera inside the safety guard provides the operator with real-time video images on the screen of the MC6 control system. The "SplitScreen" function on the MC6 enables the operator to view the video image next to the control screen page currently in use. This feature is particularly useful in complex production cells because it means the operator always has everything in view and does not have to switch back and forth between screen pages or walk round the system. This simplifies and reduces the start-up and service procedures, which in turn enhances operational reliability and keeps production downtime to a minimum. The net result is higher productivity.
In Kielce visitors can also look forward to a compact CX 80-380, which will be on display at the KraussMaffei exhibition stand. Equipped with KraussMaffei plasticizer systems renowned for their performance and reliability, the CX scores big when it comes to processing challenging materials and transparent plastics with a maximum of OK part output and a high level of precision. "Machines of the CX series have performed impressively for many years in harsh production environments and they offer the combined advantages of compact size, easy accessibility and room for peripheral equipment”, Peters explains. The fully hydraulic dual platen clamping system symmetrically applies clamping force to the mold and ensures optimum holding of the mold. The easy accessibility to the self-supporting clamp - which can weigh up to 160 tons - allows parts to be transported in all four directions and provides ample space under the mold area for peripheral equipment such as conveyors or heat-balancing units. The generous installation dimensions of the CX permit the use of large molds, as is often the case with parts subject to high demands on surface quality or multi-cavity molds. When equipped with robot types that are ideally adapted to the machines, such as the LRX 100, the AX becomes a high-performance production cell.
