Laser Welding Delivers Better Quality Mold Repair at Lower Costs

While TIG (tungsten inert gas) welding may be the go-to for mold welding in many shops, high-power pulsed laser welding is a higher-quality process that can deliver repaired molds that perform like new.

Repairing a worn mold is always going to be cheaper than replacing it. The catch is how well that refurbished mold is going to perform in the future. Will it produce parts of equal quality to the original? How long will it last until it needs repair again or has to be scrapped?

For molds going to the welding repair shop, the quality of the welds and the welding process has everything to do with answering those questions. In the U.S., the most common practice to rebuild worn cavity and core surfaces is with TIG (tungsten inert gas) welding.

However, plastics processors will find that the alternative, pulsed laser welding, delivers a superior result with less damage to the base material, so the mold will produce better quality parts and last significantly longer after the repair...READ MORE.
