Cobra uses Metal Injection Moulding to create King MIM wedge

The new Cobra King MIM wedge made from 304 stainless steel


A number of golf equipment manufacturers have for a number of years been using Metal Injection Moulding technology to produce tungsten weights which are inserted into golf club heads allowing for greater balance and hence greater direction control and higher ball speed. Now Cobra Golf of Carlsbad, California, USA, reports that it is using MIM to produce its new King MIM wedge, with the entire head made from 304 stainless steel.

Cobra states that after sintering the MIM wedges undergo a robotic polishing procedure on areas such as the sole and topline. By using robotic polishing instead of hand polishing, the company claims to produce the ‘perfect’ MIM wedge each time.

A circular micro-groove was added to the face of the MIM wedge to maximise spin, almost identical to the design found on the face insert of the Cobra King F9 Speedback driver. The company also opted to chromium plate the MIM 304 stainless wedges to ensure that they last longer for the recreational player.
