|evaporative pattern casting process
Molds have no mating surfaces and produce no burrs.
The EVA-FORM casting pours molten metal with embedded foamed molding, and it does not require removal of the model, unlike the traditional sand mold method. As a
matter of course, it requires no draft angles.
Even complicated shapes require no cores.
Even complicated shapes require no cores if they can be foam-molded and are able to be filled with sand.
Reducing the pressure in the molds achieves the following:
・High dimensional accuracy and superior casting surface smoothness
・Reduced work process
・Improved heat resistance, abrasion resistance and other cast steel properties
