CYPET’s all-electric enhancements (H14C58)
According to Cyprus-based CYPET Technologies, PET processors can finally manufacture PET bottles up to 20-litres and PET jars up to 145mm neck diameter with the world’s first all-electric single-stage injection moulding machines.
Called K19E and K30E, based on CYPET’s proprietary servo-hydraulic PET processing technology, they feature servo motors to drive hydraulic pumps, accurately delivering the required oil pressure and flow without energy waste. Besides saving an estimated 30% of electricity, this technology is said to have a faster response time and a higher movement repeatability and process consistency, compared to conventional hydraulic technologies.
The primary advantage of all-electric PET processing is cleanliness, eliminating the risk of contamination from hydraulic oil leaks. Further benefits include low electricity consumption, precision and process repeatability, availability of parallel movements for saving cycle time and minimal maintenance.
CYPET claims that its all-electric machines offer all these important benefits at an affordable investment cost, resulting in a minimal effect on total PET container production cost. Additionally, these servo-hydraulic machines offer flexibility with respect to container sizes that can be produced on a single machine thanks to swift and efficient mould changing.
Kiefel advanced stacking (H3C92)
Kiefel is presenting two innovative stacking systems designed to increase plastics packaging manufacturing productivity. ‘We constantly think about how to support plastics converters in the best possible way and, particularly, how to increase their output,’ states Kiefel MD, Thomas Halletz. ‘The forming and punching stations of our speed pressure forming machines already work efficiently, yet time can still be saved during the following steps,’ he adds.
An all-new stacking station called BEST, with an original vertical stacking concept, is being demonstrated in-line with Kiefel’s high-performance KTR 5 SPEEDFORMER cup forming machine.
‘The BEST stacking station creates optimal conditions for automated steps, such as sleeving and packaging,’ remarks Thomas. ‘Vertical stacking saves time and increases productivity and this particular model is designed specifically for the food packaging industry. No wear parts are included, guaranteeing high product safety.’
Other highlights on the stand include an ultra-efficient stacking system integrated into Kiefel’s latest KMD 78 Speedformer pressure-forming machine.
By means of a 16-up tool, biscuit trays made of PP are being produced during K2013. According to Thomas, factors such as optimal material processing and outstanding stackability have a positive impact on the quality of the formed parts. ‘The stacking system already comprises the formation of horizontal stacks and is extremely efficient,’ he says.

Inometa optimises roller technology (H4C35)
Inometa is pushing the boundaries in roll technology with modern materials such as CFRP (Carbon Fibre Reinforced Plastic).
‘We’re the perfect partner for precision and high-end solutions in the CFRP and aluminium roller manufacturing industry,’ explains Michael Kassebeer, Inometa’s film/paper sales manager. ‘This year, we plan to impress K2013 visitors with our extensive range of tailor-made lightweight rollers, winding cores, functional surfaces and CFRP designs for mechanical engineering applications,’ he adds.
Inometa’s portfolio covers the entire process chain and provides perfectly-matched products to achieve short set-up times, minimum wear and high performance. This year, focus is placed on ‘high damping’.
‘Running smoothness and process stability at high processing speeds are vital to efficiency and maintaining a competitive edge,’ remarks Michael. ‘Likewise, getting a grip on unwanted vibrations is critical to achieving longer machine component service life. The introduction of a new material can open up whole new perspectives on issues such as vibrations, thermal expansion, mass moment of inertia, degree of slenderness and corrosion,’ he continues. ‘Instead of redesigning an entire machine, CFRP can be used to optimise individual components so that they work perfectly in existing equipment, saving time and money.’
Applying finer and denser coating systems to achieve minimum surface roughness is Inometa’s trademark and today aluminium rollers can be covered with an extremely resistant hard metal coating and a roughness depth of Rmax < 0.2µm or mass-optimised CFRP rollers with chrome surfaces. For Inometa, the future lies in the integration of actuators and sensors in functional rollers and it will be demonstrating its ALDS lay-on roller with adjustable pressure application line and a sensor roller with integrated web tension sensors. The analysis software tool HCC-Easy, for measuring signal processing and evaluation, will also be available. The efficiency of modern surface coatings helps increase machine performance and reduce costs and Inometa’s high-performance Protek coatings can be integrated into individual applications. Designed to perfectly match the respective application, Protek coatings also help increase product quality. Inometa’s WinCore winding cores are produced with narrow tolerances and high concentric accuracy in order to provide excellent winding quality. The use of aluminium makes them extremely pressure-resistant and allows for continuous processes, even in humid environments. The durable aluminium winding cores can also be equipped with an RFID chip. Sacmi injection moulding excellence (H13A63)
