...-touch surface. The body of the panel is injection moulded in the first stage of the process in a glass fibre reinforced PBT/ASA blend (grade: Ultradur S4090 IGX, BASF). It is then overmoulded in the second stage with a special polyester (grade: Pibiflex, P-Group) using the MuCell process. The close chemical affinity between the two materials ensures a good bond. Compared with the conventional production of multi-layer foam-moulded parts, the new process is considerably faster, more economical, ...

...ate of PBT-GF being molded first on a multi-shot machine. A vertical rotation (stack-rotary mold, see page 107) repositions the preshot to the second parting line, where it is overmolded with a foamed thermoplastic elastomer (TPE-E, grade: Pibiflex; manufacturer: P-Group Deutschland GmbH, Filderstadt, Germany). Here, too, the MuCell process is used for foaming. The good surfaces and the low densities needed for softness are achieved in this process by carefully opening the cavity a few millimete...

... a male mold is ready in Station1 for molding the next substrate, and the substrate in Station2 is ready for applying the armrest’s soft-touch surface (Fig.3). The material processed in Station2 is a thermoplastic polyester elastomer (TPE, grade: Pibiflex; manufacturer: P-Group Deutschland GmbH, Filderstadt, Germany) that is readily foamable and specially optimized for this application. The foam structure is produced by means of the MuCell process (licensee: Trexel Inc., Woburn, USA). Hereby, an...

...s the previously required multi-step sequence, which involved error-prone manual operations, with a 2-step process on a single machine. The core of the surface is the polyester elastomer Pibiflex from the Italian P-Group, which is foamed by the use of ingenious mold technology and an interposed MuCell unit (licensed from Trexel Inc., Woburn, USA). Here, the P-Group made use of its longstanding experience with Pibiflex grades for the powder-slush process, which also requires extremely easyflowing...
