KraussMaffei has extended its hydro-mechanical dual-platen injection molding machines in the medium clamping force range with the world premiere of its GX series.

Launched at a customer event at its headquarter in Munich, the GX Series features a redesigned locking device and guide shoe, among other new features.

The company says the GuideX guide shoe, with a fixed bearing joint and optimized FEM design, ensures platen parallelism and smooth, energy-saving movements. The GearX locking system is arranged in a space-saving manner behind the platen and can reportedly be activated with the shortest possible time to continuously produce quick machine movements.

Six machines in the new GX series, with clamping forces ranging from 400 to 650 tonnes, ran at the open house in Munich. In addition to the locking systems and guide shoe, KraussMaffei also touted easy accessibility of the clamping, ejection, and nozzle areas, as well the switching cabinets and pump.

This accessible design is said to shorten set-up times and simplify maintenance.

Material-specific plasticizing solutions

KraussMaffei also offers material-specific plasticizing options, with screws optimized for everything from PC and PMMA through to PET, PC/PBT and even long fiber processing.

The in-line injection unit has a rotary piston design that transmits force centrally via the injection piston to the screw. KraussMaffei says this direct path ensures precision and reproducibility, with the GX series also regulating injection pressure and speed as a standard feature.

Updated control

KraussMaffei also updated the machine control from the MC5 to MC6, which includes an Eco button, that the company says creates an energy efficiency optimized machine setting at the push of a button. Also new is SplitScreen technology, which shows the operator all important production processes at a glance.

The MC6 also has an integrated ProcessDesigner tool that KraussMaffei says clearly presents all current processes in visual terms and enables you to modify them, depending on requirements, via drag-and-drop or swiping movements.

KraussMaffei says the modular design allows customers to specify injection units, clamping units, or drives. The fact that the machine center always remains at the same height, allows the press to be compatible with all clamping and injection unit combinations.

The GX series modular drive system offers the latest generation of the variable delivery pumps as a standard feature. Parallel movement of the ejector and core pullers is standard, and depending on the application and production cycle, the machines can be supplied with different PowerPack performance classes for more economical production.

The optional Blue Power Servo Drive technology, is said to further reduce energy consumption compared to variable delivery pumps, with savings from 10-30%, depending on the particular application. Compared with conventional hydraulic concepts on the market, savings of up to 50% are actually possible.
