KraussMaffei: Innovative solutions for injection moulding and extrusion
|
KraussMaffei showing three key injection molding technologies
An all-electric AX manufacturing cell with an integrated linear robot, targeted at technical standard applications, will produce ABS/PC battery covers in a 4-cavity mold with cycle times around 8 s. A feature of the AX-LRX cell is an ingenious idea for increasing productivity per square meter – the machine’s safety housing has been extended by the width of the conveyor belt, so that it also forms the robot safety fence. This solution saves the cost of additional gated safety fencing for the robot. The integrated, compact design knocks about 25% off the production area, compared with equivalent systems. Parts are dropped on the non-operator side towards the front of the machine.
A fast-cycling C3 machine demonstrates high productivity in a flexible multicomponent solution. The machine will produce 2C closures (PP and TPE) in a 16+16-cavity mold with 10 s cycle time. The 2-platen machine is engineered to facilitate the use of large, heavy moulds. It’s hydraulic, so long opening strokes are no problem. This all makes the C3 an ideal choice for running complex multicomponent molds with an integrated turntable. With KraussMaffei’s SP180 electric bolt-on unit and electric turntable, processors can upgrade their conventional hydraulic or electric injection molding machines – whether from KraussMaffei or any other manufacturer – for state-of-the-art multicomponent molding. 
KraussMaffei Berstorff ZE 60 R twin-screw extruder from the UTX series

For very large moldings, KraussMaffei offers machines from its MX series (800 to 4000 tonnes). An MX1000-8100 – will be in action at the NPE producing PP containers in 28 s cycle time. The MX machine, with a mechanical-hydraulic 2-platen clamp, stands for high speeds and high precision. The KraussMaffei-typical plasticizing unit guarantees top melt quality, even at very high output rates, low wear and a stable process over very long production runs. Part removal to a conveyor belt is by an LRX-S linear robot. KraussMaffei linear robots with their high-speed axes are well-suited to handling containers. The manufacturing cell comes complete with a CE conformity declaration, saving customers time, money and hassle.
ZE 60 R-UTX twin-screw extruder for gentle processing of natural fiber compounds At the NPE 2009 in Chicago, KraussMaffei Berstorff will present a ZE 60 R twin-screw extruder of its UTX series designed for processing natural fibers without energy-intensive preliminary drying. The R version with an inside/outside diameter ratio of 1.74 provides large free volume and high torques and is thus suited for processing compounds with high natural fiber content at maximum output rates.
In addition, the machine stands out for low shear energy input, excellent mixing performance, frequent melt surface renewal and low gas speed for efficient vacuum degassing. These features ensure extremely gentle and cost-efficient incorporation of natural fibers. Thanks to the free configuration of the screws and processing sections, the extruder design can be perfectly adapted to different fiber types (e.g. wood flour, wood fibers, cellulose, flax, hemp), moisture contents (up to max. 12 %) and fiber percentages (20 % to max. 70 %).
The exhibited extruder also features the typical benefits of the UTX series like clamping ring housing connections, large feed and vent openings, a highly efficient temperature control system as well as the patented housing wear protection. In addition, the R version is suitable for compounds with extremely high filler content, TPE processing, reaction and concentration processes as well as for residual degassing.
Another KraussMaffei Berstorff exhibit at the NPE is the in-line color measuring system providing in-line quality control based on melt color measurements at the discharge from the die. This helps to avoid detrimental reflections normally caused by color measurements carried out on pellets. The spectrometer is designed for monitoring the compound quality during color changes and reduces start-up scrap. Furthermore, any defects in material metering or pigment premixing can be detected immediately.
In particular with transparent melts like PET, PC and PS, a transmission polymer melt probe ensures close color tolerances, while a reflection polymer melt probe is used for this purpose with color concentrates. The process in question was developed jointly by Equitech and KraussMaffei Berstorff and is now ready for use in production environments.
