Semi-Permanent and Permanent Mold Casting

Zeman Tool specializes in semi-permanent and permanent mold casting for prototype and production. Molds are 3D-machined from CAD data. They are created using various materials such as alloyed steels, tool steels, or premium castings. The molds are heat treated, and the high-tolerance contours are high-speed milled and/or EDM finished, resulting in limited or no benching/polishing.
