2016 | Thermoforming
KraussMaffei has demon- strate its refined
FiberForm
process, which combines injection
moulding and thermoforming technologies
centrally located drinking hole). To accompany the lids, Kiefel will produce a range of
disposable cups on its latest generation Thermorunner KTR 6.1 Speed. Higher performance drive systems in this model help to increase production rates by to up to 45 cycles per minute. A significant rise in punching force – combined with
a greater forming area – increases the number of cavities. A newly developed pre-stretching plug is actuated by a powerful linear motor. Faster pre-stretch- ing has a positive effect on material distribution and processing speed. A sophisticated stacking and picking system allows the KTR 6.1 Speed to produce even thin-walled cups in a reliable manner. The KIST vertical stacking system works without brushes or rubber elements.
FiberForm refinements KraussMaffei has further refined its FiberForm process – which combines injection moulding and thermoforming – and will present a close-to-production manufacturing cell at K2016. Visitors will be able to watch a prototype component for the automotive industry being made. FiberForm entails the thermoforming and over- moulding of organic sheets, which are plate-shaped, semi-finished products with continuous fibres made of glass, carbon or aramid embedded in a thermoplastic matrix made of polyamide (PA), polypropylene (PP) or other matrix systems. In this process, these semi- finished products are first heated, reshaped in the injection mould and then back-injected with a fibre- reinforced polymer. “Parts with integrated organic sheets have signifi-

cantly better mechanical properties compared to those that are purely composed of short fibre-reinforced injection moulding material. For example, manufactur- ing complex structural components results in com- pletely new design options,” said Hans Ulrich Golz, managing director of KraussMaffei. It is important to heat the organic sheet correctly,
because overheating leads to thermal degradation of the matrix – meaning it must be scrapped. KraussMaf- fei developed a control process for infrared emitters that is integrated into the MC6
machine control system. The control process enables fast heating – without exceeding the set temperature.
In mould expertise Illig will showcase its latest developments in thermo- forming and packaging – including its in-mould labelling with thermoforming (IML-T) technology. It will demon- strate its IML-T line IC-RDM 70K with the compact IML unit RDML 70b for flexible decoration of nearly any cup geometry. Also making its debut at the show will be a flexible product handling system. Adapted for Illig IC-RDK 54, this combination accelerates production for enhanced productivity, says the company.
Tilting platen WM Thermoforming Machines is to unveil a new thermoforming machine with a tilting platen. The Twist 700 is designed to produce containers in PP, PP/EVOH and PET that require high quality standards and narrow dimensional tolerances. The company will reveal more details at the exhibition. Also at the show, the company will run an In-Line
extrusion and thermoforming plant for the production of PP cups. WM recently delivered its 110th In-Line plant system for extrusion and thermoforming – in Intec 900/3 – for the production of two-colour PP cups, to a customer in North America. Later this year, the company plans to extend the
In-Line range with the Intec FT 900/3, for co-extrusion of PP and PS.
