An essential influence of the injection temperature and pressure as well as the surface roughness of the mould cavity on the surface roughness of mouldings from polyamide-6 (Tarnamid T-27), glass-fibre reinforced polyamide-6 (Itamid 353) and polytrioxane (Tarnoform 300) has been ob served. The investigations have been carried out according to the statistical method of design of experiments.
