Several glass fibre reinforced PP grades were injection moulded using a two-gated hot runner mould. Microhardness, tensile impact strength and falling dart impact energy were monitored at different points of the moulding surface to evaluate the differences between bulk and weld line properties. Microstructure was studied by optical and scanning electron microscopy
