Abstract

A method for manufacturing a rear spoiler for a motor vehicle comprises the following steps :(a) a spoiler-shaped core containing holes distributed over its surface area is made by injection-moulding hard synthetic (preferably polyurethane) foam in a first closed mould and then leaving the foam to cure ; (b) the core is removed from the mould and hard plastic (preferably polyurethane) pins are pressed into the holes so that their pointed ends stick out from the core surface by a distance equivalent to the intended surface layer coating (1b) for the core ; (c) the core is placed inside a second mould where the pins lock it into a set position and then hard plastic (preferably polyurethane) is injected into the mould to fill the gap between the core surface and the inside of the moulds against which the pins are in contact ; and (d) the surface coating is allowed to cure inside the mould and then the finished spoiler is removed. Spoilers made by this method are al so claimed.
