PCT No. PCT/JP95/01857 Sec. 371 Date May 3, 1996 Sec. 102(e) Date May 3, 1996 PCT Filed Sep. 19, 1995 PCT Pub. No. WO96/09156 PCT Pub. Date Mar. 28, 1996A method which makes it possible to simultaneously injection-mold a number of spherical moldings without causing increase of runner loss, and is a method of preparing spherical moldings by coupling molding forming parts with each other through a bridge of 0.1 to 10 mm2 in sectional area for feeding molten resin, arranging a structure in which a plurality of molding forming parts are coupled with each other through the aforementioned bridge with respect to one gate, and performing molding, thereby obtaining a sphere series in which a plurality of spherical moldings are coupled with each other through a bridge part.
