  • Abstract This study investigates the influence of injection molding process parameters on the tensile properties, wear properties and impact toughness of Polyoxymethylene (POM). Four manufacturing parameters including filling time, melting temperature, mold temperature and packing pressure were considered. The author used the traditional experimental design to understand the general tendency of each injecting parameter. Then, the author combined the Taguchi experimental design, analysis of variance (ANOVA) and principal component analysis (PCA) to optimize the manufacturing parameters.
    The results of traditional experiment design showed that the best manufacturing parameters were filling time 1.5 s, melting temperature 200℃, mold temperature 90℃ and packing pressure 75 MPa for tensile strength. The best manufacturing parameters were filling time 1.5 s, melting temperature 215℃, mold temperature 75℃ and packing pressure 75 MPa for impact toughness. For the wear properttis, the best manufacturing parameters were filling time 0.5 s, melting temperature 200℃, mold temperature 90℃ and packing pressure 55 MPa in P–direction specimen, while they were filling time 1.5 s, melting temperature 200℃, mold temperature 90℃ and packing pressure 55 MPa in AP–direction specimen.
    The results of Taguchi experiment design and ANOVA showed the optimum combination of manufacturing parameters was filling time 1.0 s, melting temperature 200℃, mold temperature 90℃ and packing pressure 75 MPa for tensile properties. Melting temperature was the most significant manufacturing parameter among them. When we consider the tensile strength, friction coefficient and impact absorb energy, the analytical results of Taguchi experiment design and PCA showed that the optimum combination of manufacturing parameters was filling time 1.5 s, melting temperature 200℃,mold temperature 60℃ and packing pressure 65 MPa. Also, melting temperature was the most significant manufacturing parameter.
