Problems solved by technology

However, both heating methods have the disadvantage that the heating of the mold is energy-intensive and moreover the heating of the mold takes place very slowly
This particularly negatively affects the production cycle during the coating process

Embodiment Construction

[0050] Figures 1 to 3 The production method according to the invention is shown in a device according to the invention. The device according to the invention comprises a first mold half 3 and a second mold half 4 . A decorative part 2 and a decorative layer 1 are embedded between the half-mold 3 and the half-mold 4 . Furthermore, a heat-activated adhesive 5 is applied between the decorative layer 1 and the decorative part 2 . Here, the first mold half 3 and the second mold half 4 have a contour corresponding to the outer contour of the decorative part 2 . Both the first half-mold 3 and the second half-mold 4 are provided with cooling channels 9 throughout. Here, the cooling channels 9 are mainly arranged on the side of the mold half facing the decoration 2 and the decoration layer 1 . An inductively heatable insert 6 is also introduced into the first mold half 3 . In this embodiment, the insert 6 is completely enclosed by the remaining area of ​​the first mold half 3 . ...

Abstract

The present invention relates to a method and apparatus for coating a decorative layer (1) on a decorative part (2), and the decorative part is particularly used for the internal space of a vehicle. The method at least includes the steps of embedding the decorative part (2) between the two mold halves (3, 4); positioning the decorative layer (1) on the decorative part (2); fixing the decorative part (2) and the decorative layer (1) between the first mold half (3) and the second mold half (4); and exposing the insert (6) capable of induction heating of the first mold half (3) to the dynamic magnetic field to heat the mold halves.

Description

technical field [0001] The invention relates to a method and a device for applying a decorative layer on a decorative part, especially for an interior part of a vehicle. Background technique [0002] In order to upgrade the interior space of the vehicle, interior parts in the vehicle are usually decorated with a decorative layer. For this, the decorative layer is glued on the interior part. Usually heat-activated adhesives are used here which are arranged between the decorative layer and the interior trim part. Next, the decorative layer is pressed against the decorative part in a heatable press-coating die, and the heat-activated adhesive is activated by the heat released by the press-coating die. [0003] Heating of the coating die is usually achieved by means of electrical resistance heating or an external heat source that introduces a heat medium through the die. However, both heating methods have the disadvantage that the heating of the mold is energy-intensive and m...
