Title
(EN) METHOD FOR APPLYING A TOP COAT TO A PLASTIC PRODUCT IN THE MOULD
(FR) PROCEDE D'APPLICATION D'UNE COUCHE DE FINITION SUR UN PRODUIT EN MATIERE PLASTIQUE DANS UN MOULE
Abstract
(EN)
A method for the application of a top coat (12) to a plastic product (14) in the mould (1) in which said product is moulded in one process step, without a specific after-treatment also being necessary for this purpose, by first applying the top coat (12) which is to be applied to the product to at least one wall of the mould or a part thereof, on the side where the product is to be moulded, and then moulding the product in the same mould. The method according to the invention is based on the combination of injection moulding and the application of a top coat by means of electrodeposition.
(FR)
Procédé d'application d'une couche de finition (12) sur un produit en matière plastique (14) dans un moule (1) dans lequel ledit produit est moulé en une seule étape, sans qu'un post-traitement complémentaire ne soit nécessaire à cette fin. Le procédé consiste, dans un premier temps, à appliquer sur au moins une paroi d'un moule, ou sur une partie de cette paroi, la couche de finition (12) destinée à être appliquée sur le produit, et ce du côté où le produit sera moulé, puis à mouler le produit dans ce moule. Ledit procédé associe un moulage par injection à l'application d'une couche de finition par électrodéposition.
