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 toally 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 mehods such as EDM'ing, grinding, machining, plating, etc.
The repairs are produced by a low heat, non-arcing welding process. This produces a weld with the least amount of heat so shrink lines and other cosmetic defects are eliminated.
