TecPart 2019 Awards highlight moulding innovation and sustainability


The 2019 Innovation Awards from the GKV and TecPart associations in Germany were announced – as is the tradition – on the first day of the K Show in October. The prizes reward technical achievements by plastics processors, and recent innovations by injection moulders often feature prominently in the awards. Michael Weigelt, Manag-


ing Director of GKV/TecPart, commented on the sustainability benefits of plastics that are showcased by the award winners. He said: “Products and entire assemblies made of conventional materials are constantly being replaced by re- source-saving solutions made of polymer materials.” Automotive supplier Kunststoff


The Audi A7’s illuminated belt buckle won an award for Kunststoff Helmbrechts


Helmbrechts (KH) was a major winner, receiving three TecPart 2019 awards. The awards were for a sophisticated tooling solution for the production of the illuminated belt buckle in the Audi A7, the vanishing effect of a 3D white panel, and a chrome finish painting


German consultancy Design Affairs and which it showed at K2019. One of these designs is for a portable air treatment device which is part of a modular and multi-functional appliance system. Covestro says: “The high level of standardisation and modularisation of the system allows the potential use of recycled materials, and the product’s components can be easily adjusted, upgraded or refurnished based on the user’s needs to expand the product’s life-span.” For the proto- type shown at K2019 the company used a flame- retardant Bayblend PC/ABS grade for safety and versatility. At the AMI conference, Meine said Covestro has been working with electronics customers in Asia on the use of recycled PC materials in new devices. “The task was using recycled materials to make a cover for notebooks. We started from water bottles which, in principle, are made from quite pure polycarbonate. They are used for many years, then shredded and we develop different grades for the electronics industry.” The big challenge, he said, is getting the right

with coating thickness of just 1 µm.


KH said: “The challenge


presented by the belt buckle was that the PC optical fibre had to be surrounded by an inner and outer frame of PC-ABS without any shadow being created by the connec- tors. The KH tool-making team developed a twin-turn tool in which the moveable and the (usually) fixed side

and include water cooler bottles, car headlamps and PC sheet. It is important to source transparent PC materials, he said, as these are not only easy to colour but are also better for quality reasons, as compounds in coloured PC can affect quality during reprocessing. Meine said electronics companies demand


materials that have a good surface quality and meet flammability standards. Covestro’s answer is to blend recycled PC with virgin material. Passing a sample notebook cover round the conference audience, he said “the notebook cover contains 35% recyclate, and with 65% virgin material the quality is controlled”.
