K2025 | EXHIBITION REVIEW


processing advantages during injection moulding; and an expanded offering of flame-retardant, halogen-free PBT products (Radiflam B) with a version that adds hydrolysis resistance. The company is also developing PAs that combine flame retardancy with hydrolysis resistance. “These are important in applications for the thermal management of batteries and power electronic systems,” said Erico Spini, global marketing manager for high performance polymers at Radici. The company also highlighted its expertise in


metal replacement, such as when lightweighting parts in the automotive industry. In one case, replacing a die-cast aluminium component with one made of Radilon A RV500RW – a PA66 with 50% fibre content – helped to halve carbon footprint.


Another metal replacement application seen at


K was Genny Zero, a self-balancing personal transporter whose total weight was reduced from 110kg to 60kg by replacing metal with PA polymers. The project was a partnership between Radici, Acerbis and Genny Factory. In photovoltaics, Radici showed a line of


red-phosphorus flame-retardant PA66 products (Radiflam A) with two grades with low-temperature impact strength, property-retention under outdoor exposure and a reduction in the corrosion of metal contacts. For home appliances, it showed halogen- free PAs with good mechanical characteristics and resistance to hydrolysis – including materials meeting the required standards for appliances operating without supervision (IEC 60335). � www.radicigroup.com


Röhm showcased several lighting and household applications of its Plexiglas moulding compounds. One is its Optical HT special moulding compound, which Polish company Lena Lighting uses to produce the multi-lens arrays in the Tiara LED Pro streetlight – which was on display at K. Its high luminous efficiency remains undimmed for many years, with the material able to withstand thermal ageing, sunlight and weathering. It also exhibited a luminaire


profile – produced by BWF Profiles – for the Ridi Linia Evo continuous-row lighting system, made from Plexitlas ProTerra M5, which contains 30% recyclate.

of its Thermomix TM7 mixer – using Plexiglas Hi-Gloss NTA-5 to give it a housing with high impact resistance, a pleasant feel and resistance to cleaning agents, says Rohm. In addition, the lower section of the housing of


Arçelik’s new yoghurt maker is a glossy black component made from impact-resistant Plexiglas Resist in a neutral-grey colour. An integrated black panel display only becomes visible when the appliance is switched on. And BSH has equipped a dryer in its new iQ 700 series with an interior pane made from a Plexiglas moulding compound. Because PMMA is lighter than glass, it reduces the total weight of the appliance. � www.roehm.com


Netherlands-based Stork IMM launched its all-electric 6600-3550 model with two-component (2K) moulding capability – for making thin-wall food packaging and industrial paints/buckets. The machine’s improved platen stiffness, linear guiding under the movable platen and clamped toggle pins results in extended mould life. This means higher part quality and productivity in even the most demanding applications, it says. At K2025, the 6600-3550 was used to produce a two-cavity 5-litre pail with handle and in-mould labelling (IML) in 5.9 seconds. The live showcase underlined the machine’s ability to combine speed, precision and energy efficiency. “This machine extension satisfies growing demand for injection moulding machines that meet the productivity demands of the packaging market,” said Tony Mekenkamp, sales director at Stork. The all-electric range is designed for flower pots,


pails, food packaging and other thin-walled products. With clamping forces ranging of 2500- 9000kN, they provide: fast injection speeds up to 450 mm/s enabled by twin low-inertia electric motors; improved platen stiffness and stability for maximum product quality and longer mould lifetime in high-cavity moulds; rack-and-pinion design for greater energy efficiency and long-term durability; and, the reliability to run 24/7 at short cycle times, with low energy consumption.
