Welding on Class “A” mold finishes is just part of the daily routine for our highly trained class ‘A’ mold welders at MPD Welding-GR, Inc., of Grand Rapids, MI. From large auto body plastic molds to diamond polished crisper pan molds for the refrigerator industry. We guarantee color match on all of your AISI P-20 molds.
The term color match was coined to describe a heat treating procedure by which three separate regions in the cavity of a welded P-20 mold steel are processed in order to achieve perfectly uniform texturing and / or diamond polish: parent metal, HAZ (heat affected zone), and weld deposit.
In order to consistently accomplish perfect color match, three fundamental components must be in place: carefully calibrated steel treating furnaces, preferably nitro vacuum; highly skilled technicians; and properly selected tool steel filler metals.
Hardness variations and grain growth that are created by the arc stream (ranging from 5000° to 10000°), combined with rapid quench, must be precisely re-tempered and quenched in order to restore the welded cavity surface to post welded consistency prior to etching or diamond polish.
