On 7 September 2018, hot runner specialist Synventive invited injections moulders and mould makers to Bensheim, Germany, for the 20th Bensheim Technology Days. This year's edition of the annual event was held under the motto of “Trends in Automotive – Increased requirements in injection moulding with regard to surface finish and functionality of new part concepts”.
Seven presentations were held by experts on different aspects related to automotive design and functionality. All in all, Synventive's technology day made it clear that the demands placed on the quality and functionality of surfaces are rising sharply. The changes in the automotive sector have a great influence on which technologies will play a role in the future. The presentations by experts provided insights into different perspectives on the subject of surface finishes.
Klaus Gerst from Bertrandt Ingenieurbüro spoke about the vehicle interior of the future and the challenges for a development service provider. His company is already working on concepts for surfaces to be adapted in autonomous driving.
The second presentation was held by Ruud Heerkens from Sabic Innovative Plastics on the topic of “Improving the surface aesthetics of large panels using active gates”. He showed examples of improvements of the surface quality when applying advanced flow control in injection moulding.
Philipp Lachner from Krauss Maffei Technologies spoke about surface technology 2.0 – trends and process solutions for an economic application. Among the solutions presented were Dynamic Mould Heating (DMC), Color-Form, a technology combining painting and injection moulding, and labeling and decorating processes.
Other speakers included Christian Götz, Hans-Jörg Schreyer, and Volker Gründel from Synventive Molding Solutions. The experts presented applications and developments of Synventive's hot runner technology, for example hot runner sytems for applications with long glass fibres.
The day was rounded off with a guided tour of Synventive's facilities, inlcuding the departments for manufacturing, development and assembly. Afterwards the participants met for dinner followed by a visit to the traditional Bensheim wine festival.
