Applications and Capabilities

The MoldMender Micro Welder repairs plastic injection molds, rubber processing molds and die casting molds and dies made of steel. Typical applications are parting lines, corners / edges, pin holes / scratches, machining errors, etc

Repairs are accomplished by producing interlinking spot welds to totally bond the repair material to the desired area of the work piece. The repair material used is normally the same material as the work piece, producing a fully hardened repair ready for finishing. Since the amount and location of the repair material can be precisely controlled, the minimal finishing that is required can easily be performed with any of the standard methods such as EDM'ing, grinding, machining, plating, etc.

The repairs are produced by a low heat, non-arching welding process. This produces a weld with the least amount of heat so shrink lines and other cosmetic defects are eliminated.

Metallic ribbon (thin strips of steel) with the same composition as the work piece are welded continously to the work piece a spot at a time. This allows consistent quality welds with minimal heat. Minimizing the heat on the repair area makes it possible to weld without shrink lines, distortion or discoloration which is commonly associated with other welding processes.
