Foil Body, Method for Back-Injection Molding a Foil Body and Back-Injection Molding Tool

摘要

The invention relates to a film body, a method for the back-injection molding of a film body and a back-injection molding tool therefor. In particular, the invention relates to a method for the back-injection molding of layer electrodes (1) for producing touch-sensitive sensors for example for touch screens.;Parts of the layer electrode (1), which after the back-injection molding should still be able to move freely, are covered by a sacrificial film (3) before and during the back-injection molding.

1. Method for the back-injection molding of a layer electrode for producing a touch-sensitive sensor, wherein the layer electrode has at least one area not to be back-injection molded comprising the following method steps:
covering the area of the layer electrode, which is not to be back-injection molded, with a sacrificial film; introducing the layer electrode and the sacrificial film into a back-injection molding tool; back-injection molding the layer electrode and the sacrificial film into a molded body; and forming a touch-sensitive sensor from the produced back-injection molded body.
