<p>A method of manufacturing spheroidal moldings, by which a multiplicity of spheroidal moldings are injection molded at a time without increased runner loss. In the method, molding is performed with such an arrangement that molded portions of moldings are connected to one another via bridges, through which melt resin flows and which has a cross-sectional area of 0.1 to 10 mm2, and a plurality of molded portions of moldings are connected to one gate via the bridges, whereby a chain of balls comprising a plurality of spheroidal moldings (1) connected by bridge portions (2) are obtained.</p> |
