a plastic moulding includes a rigid support which is joined over at least one surface area to at least one film . the film has a fold at the edge of the plastic moulding which is placed around the plastic support . the manufacture of this plastic moulding takes place such that first of all the film is brought into the final shape including the final fold and that only thereafter is the material of the plastic support applied to the plastic film as a melt and both pressed into the completed fold and also collectively brought into the final shape by a compression moulding process .
