Since launching the GX series of machines last year, KraussMaffei has now expanded the sizes in the range. The GX series will make its K Show debut in the form of a 900 tonne machine moulding a packaging application with a cycle time of seven seconds.
By the time of the show, 44 different machine combinations will be available across the 400 to 900 tonne range. The machines are adapted to suit many different applications using various PowerPack drive modules. “Minimal cycle times with ideal efficiency. The GX series impresses our customers with its quick movements and minimal energy consumption,” said Frank Peters, Vice President of Sales at KraussMaffei.
On the GX 900-8100 parts will be demoulded using a linear robot and transferred to a second robot via a “handshake” movement. The two LRX 250 HS robots are both in the high-speed configuration, which improves the demoulding time. Both robots and the machine will be equipped with the MC6 control system. The automation and the machine can therefore be operated from every control cabinet. A visible monitoring function for the working area constantly provides the operator with a view of the robot's working area on the display and facilitates tooling and optimisation processes.
The aim of every plastics processor is maximum machine production time. With its project engineering and system competence KraussMaffei offers qualified support in the search for an optimal solution for every customer. At K 2013 the company shows a fully automated solution for horizontal mold change on the GX 900-8100. This is ideal for production plants with frequent mold changes, which are the result of small lot sizes or released quantities. The processors benefit from reduced storage and JIT (just in time) delivery to the customer.
Together with its partner EAS, KraussMaffei will present a quick change system with fully automated production conversion within three minutes. In this time the preheated mould from the mould changing table is inserted in the machine and secured in the machine using magnetic clamping plates. The connections for the media supply are provided by multi-coupling systems. Both robots will operate independently of the gripper station using the hand compatible for the current mold. The MC6 control system is simple to program and guarantees smooth processing of all processes for automatic production conversion, including timely warm-up phase and preparation.
