Abstract

Throughout the world car industry has been using window encapsulation for a few years now. This technology is mainly used in production lines and is called RIM for polyurethane reaction injection moulding.

This technology, however brings about some problems such as:

– glass breaking during mould closure,

– high production cost,

– systematic rough edges.

The PSA Group (Peugeot-Citroën), a pioneer in this field, in collaboration with SAIREM has launched a new innovating process for window encapsulation by using the 50 Ω RF technology for gelling PVC Plastisol.

The study was followed by an industrial prototype. Industrial equipment was then installed at WEBASTO HEULIEZ for window encapsulation of the sunshine roof for the Citroën Xantia.

The authors describe the principle of window encapsulation and the different existing processes. He describes the 50 ΩRF technology, an industrial installation and the constraints of this technology in order to get maximum efficiency.

In the conclusion they present a technical and economical analysis of the different solutions for window encapsulation. They also present the advantages of the 50 Ω RF technology and the new opportunities it offers.
