Chris' Tips

Chris Chris' Tips
All Martin Model & Pattern castings are fully annealed for easier machining. When molten iron is poured into a sand mold, it cools very quickly where it contacts the cold sand. Quick cooling being the formula for hardening iron, this results in a very hard surface, or skin, on the casting. It's commonly known that you must address this hard skin when you start machining a casting. But Martin Model castings go through another heat treat process. After the castings have cooled, they are once again heated to a high temperature, but this time they are cooled slowly. This ensures that the castings are evenly soft throughout, and that there is no hard skin on the surface
