METHOD OF MANUFACTURING SPHEROIDAL MOLDINGS

摘要

The present invention obtains a 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 mm<2> 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 1 are coupled with each other through a bridge part 2. <IMAGE>
