Ninomiya, Fujikawa and  Michishita of Mizuno Corporation, Japan, developed a mold having a parting line along dimples which allows manufacturing of golf balls free from burrs.  The mold consists of an upper mold and a lower mold separable from each other and with convex areas for forming dimples. Some of the  convex portions lies over the equator of the cavity, a parting line, which corresponds to the boundary between the upper mold and the lower mold.  (RDC 10/24/2012)

Metal injection molded putter
 
Hirsch and Soracco of Cobra Golf Incorporated, California, formed golf club heads using metal injection molding. The method of the invention allows for a lower volume of powdered metal than current metal injection molding processes thereby decreasing overall production cost.  A  frame for the golf club head consists of stainless steel, titanium, titanium alloys, tungsten alloys or aluminum alloys. The frame is positioned into a mold where a combination of a powdered metal and a binding agent is injected into the mold and around the frame. The powdered metal consists of stainless steel, titanium, titanium alloys, tungsten alloys or aluminum alloy  particles with an average diameter of less than about 40 micrometers. The binding agent may be water soluble. (RDC 8/16/2012)
