Whether they’re an amateur enthusiast or a Michelin-starred pro, chefs love a well-lit workspace. Improving illumination in kitchens is also something that’s close to the heart of German plastic component manufacturers Alfred Kron GmbH. Engineers at the injection mould specialists have recently replaced their hot runner systems with a new set-up supplied by Günther in Frankenberg, with positive results. The new technology is said to help the quick connectors used in light fittings and electric drives reliably establish contact between conducting paths and electric supply lines.

The use of plastics in kitchens has been problematic for some time because unsupervised appliances must meet the requirements of IEC 60335-1. Stanyl TE250F6 is one of the few high-temperature polymers approved by VDE for this field, along with other polymers such as DSM’s For Tii (PA4T), Stanyl (PA46) and Akulon (PA6). Their mechanical performance (such as weld-line strength) is claimed to make them especially suitable for overmoulding contacts and for parts that need to withstand a high degree of stress during installation. The above DSM materials are also said to increase the safety of unsupervised kitchen appliances.
