Process developement for manufacturing hybrid components using an in-mould infrared heating device

Abstract

Large-scale production technologies for hybrid structures are necessary to force lightweight design into automotive applications. The aim of today’s research is to find economic strategies for efficient manufacturing processes. This study adresses a process development for manufacturing instrinsic hybrid components using an in-mould infrared (IR) heating device [1]. The consisting concept of an integrated IR-radiator [1] has been developed to improve manufacturing processes for material hybrid components dominated by thermoplastic materials. This approach makes use of a substitution of steel with transparent ceramics at local areas of the mould and an the integration of IR-radiators. Thus, the problem of rapid temperature loss of thermoplastic preforms through direct contact to the cold mould surface can be avoided. This concept has been build up and comprehensive investigations of its usability has been made. The integration of a heating device enables a reduction of station times by utilizing dead times (interims) for heating processes. This also allows a gentle processing of material. The ceramic-faced surface of the preform can be heated up focussed to necessary processing temperatures at specific times. This research work discusses a process development using an in-mould IR heating device.
