Zeman Tool engineers custom foundry tooling solutions or build customer designed tools. We build tooling for many types of casting processes. Zeman Tool accommodates single or multiple mold production.
Zeman produces foundry tooling out of various materials (steel, aluminum, urethane board, wood). Zeman’s range in tooling experience includes products from engine blocks and outboard motors to motorcycle clutch levers and large gears.
Low-pressure permanent mold (LPPM) casting with sliding mold halves.
Four cavity low pressure permanent mold (LPPM) casting.
Six cavity lower Pressure Riserless casting (PRC) mold that cast automotive knuckles.
Six cavity left and right hand control arm water cooled low pressure mold.
Custom static pour permanent mold with a single cavity.
Tilt pour permanent mold casting of an oil pan.
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.
We have experience with designing and manufacturing:
Our precision sand cast patterns are produced from a variety of materials for high volume production (tool steels, cast iron, and aluminum) or for the supply of short-run manual prototype applications (composites). Zeman produces single or multiple cavity corebox configurations of varied sizes depending on your unique specifications and are completely rigged for a variety of core-blowing machines.
