Innovative Procedures to produce decorated parts with Softtouch Surface Haptics
This article presents a new procedure to produce softtouch decorated parts. First aim is to realise a soft surface with constant surface properties along the flow path by sequential back injection of a decorative film with first a soft TPE layer and second a rigid thermoplastic carrier. In a second phase the weak points of the conventional back injection of soft touch foam films concerning the unsteadiness of the surface hardness are examined. By use of the special injection moulding processes back injection compression moulding and back foaming a decor saving procedure is worked out in order to achieve parts with soft and constant surface properties.
