When you’re tasked with making minor repairs of molds and dies, high-powered, traditional welding methods might cause you more headaches. You don’t want the excess heat that can damage adjacent areas and expand the heat affected zone. At the same time, you also need a precision weld that will solve your problems, quickly.

There are several micro welding options to choose from. All too often, however, micro welders involve cumbersome and time-consuming setups, whether it’s gas, expensive microscopes and hardware, or even more expensive laser sources. We believe there’s a better way that’s both simple and cost effective. That’s why we developed the MoldMender Micro Welder.

The MoldMender Micro Welder delivers simple and cost-effective mold and die repair in-house through a low heat, non-arcing welding process. Instead of sending molds out for repair or scrapping them prematurely, the MoldMender solves scratches, imperfections, pin holes, parting lines flashing and other mold and die imperfections, and it does it all with no welding experience necessary.

Mold and die repairs are accomplished by producing interlinking spot welds to totally bond the repair material to the desired area. A simple process of rolling the electrode permanently bonds the welding material to the workpiece, resulting in a consistent quality weld with minimal heat. Further, minimizing the heat on the repair area makes it possible to weld without shrink lines, distortion, or splatter on adjacent areas, a common occurrence with other welding processes.

The ribbon, wire, paste, or powder repair material used is normally the same material as the workpiece, producing a fully hardened repair ready for finishing. Since the amount and location of the repair material can be precisely controlled by machine setting, the minimal finishing that is required can easily be performed with any standard methods such as EDM'ing, grinding, machining, plating, polishing, etc.

With no need for gas or a welding helmet, the fully portable MoldMender can be carried directly to the press for immediate repairs. See the MoldMender in action in this 60-second clip where a tool needed its edge built up:
