Abstract
Method for making an optical unit 1 for vehicles, according to which an insert 20, having an external surface 21 complementary to an internal surface of a casing 2 composed of a reflecting body 3 and by a transparent element 8, is formed by injecting a water- soluble or heat-meltable material into a mould 30 and forcing the material itself into contact with the mould 30 by means of a jet of fluid under pressure; the insert 20 being, therefore, arranged inside a further mould 14, and the casing 2 being made in a single piece, injecting a thermoplastic material into a further mould 14 and then extracting the insert material 20 from the further mould 14 through an opening 5 in the casing 2. (Figures 1 and 2). <IMAGE>
