Abstract
The cavity of a mold for making a plastics material part is lined using at least two, preferably decorative, pieces of film. The pieces of film are shaped and cut out so as to be accurately juxtaposed in the film cavity. Molten plastics material is introduced into the mold cavity in register with each piece of film in controlled manner so that the front of plastics material flowing within the mold cavity for the purpose of filling it advances within the mold so as to stretch each piece of film in centrifugal manner so that the film is neither displaced nor folded. The fronts of plastics material advancing over each piece of film meet either in locations of the mold where there is no film or else in register with the facing edges of two pieces of films, where appropriate, so that the entire surface of each piece of film is covered in a layer of plastics material. If necessary an additional quantity of molten plastics material is then introduced into the mold cavity so as to fill it completely.
