Abstract: The invention particularly relates to a method of applying a permanent coating to a plastic surface of a first part, comprising the following steps: applying to said plastic surface a layer of a polyamide-based hot-melt material, maintaining this layer of hot-melt material on said plastic surface for a period of time ranging from a few minutes to several hours, removing this layer of hot-melt material from this plastic surface; and applying a permanent coating to said surface, said permanent coating being based on polyurethane, an epoxy resin or polyesters, a polycarbonate and/or an acrylic resin; as well as the use of such a method in the automotive industry.

Abstract: In this method for manufacturing a vehicle part, the following steps are implemented, applying a first varnish coat to a transparent part, applying a paint coat to the first varnish coat, applying a second varnish coat to the paint coat, and irradiating the paint coat and the second varnish coat in part with laser radiation.

Abstract: In this method for manufacturing a vehicle part, the following steps are implemented, applying a paint coat to a transparent part, applying a first varnish coat to the paint coat, irradiating the paint coat and the first varnish coat in part with laser radiation so as to etch the paint coat and the first varnish coat, applying a transparent primer coat to the first varnish coat, and applying a second varnish coat to the transparent primer coat.

Abstract: The invention relates to a method for producing a motor vehicle part (10) made of a plastic material, said method comprising a step of spraying a product, and the part comprising an area to be protected during the spraying. The method comprises the following steps: applying a fluid material forming a temporary masking layer on the area to be protected, said step being carried out automatically; spraying the product onto the part (10); and removing the temporary masking layer.

Abstract: The invention relates in particular to a method of painting a motor vehicle bodywork part, the method comprising the steps consisting in applying a first component on the part, in allowing the first component to tension on said part during a so-called “flash-off” stage, then in applying a second component on the part, the part being moved by a handler robot in front of a stationary applicator during the two spraying steps and in front of flash-off acceleration means during the flash-off stage. The invention also provides a painting booth having at least one stationary applicator for applying a paint component on a part carried by an arm of a handler robot that is present in the booth, and means for accelerating the flash-off of the part, the means being arranged in the booth in such a manner that the part can enter into the field of action of the acceleration means while being carried by the same handler robot.
