Despite its split off from the GKV association of German plastics processors earlier in the year, the Frankfurt, Germany-based TecPart plastic technical parts trade association presented winners of its 2022 innovation awards on the first day of the K 2022 fair.
The ceremony continues a long-standing tradition at K fairs since 1974, but this time on its own TecPart booth. Of the 11 awards, nine were for molded parts, but there were also two awards for thermoformed parts.
Marbach am Neckar, Germany-based BBP Kunststoffwerk Marbach Baier GmbH (Hall 6, Booth E76) was awarded for the battery housing for the Mercedes Benz Axor truck, involving overmolding of four rotationally symmetrical steel discs with 35 percent glass-fiber-reinforced nylon 6. The application demands close tolerances in the 1/100th range for precise insertion of the steel discs into the injection mold.
BBP molds the housings on a 2,000-tonne clamping force injection molding machine from Munich, Germany-based KraussMaffei Technologies GmbH (Hall 15, Booth C24-D24). The part weighs 10.2 kg and BBP succeeded in obtaining 28 percent weight reduction over the previous version housing, which was in 40 percent long-glass-fiber-reinforced polypropylene.
Saalburg-Ebersdorf, Germany-based ETM Engineering Technologie Marketing GmbH was awarded for an air line, a single multi-component part used to feed fresh air to combustion engine turbochargers. It consists of a hard 30 percent glass-fiber-reinforced polybutylene terephthalate component with an integrated sensor and soft TPC-ES thermoplastic polyester bellow component, which protects the air line from movement.
Helmbrechts, Germany-based Kunststoff Helmbrechts AG (Hall 8A, Booth F11-02) received an award for a "piano black" screen-printed in-mold labeled (IML) "black panel effect" capacitive steering wheel control unit for the Volkswagen ID3 electric drive car.
The unit uses the PET film-based FFB functional film bonding technique developed by Fürth, Germany-based Leonhard Kurz Stiftung & Co. KG (Hall 5, Booth A19-E09) and it's PolyIC subsidiary to provide capacitive operation. The previous two-component control module had required 10 molding tools, now just one single mold tool suffices.
