CERAMIC CASTING METHOD
Ceramic casting uses monolithic shapes and cores made of refractory materials, which are subsequently treated. It is an ideal process for conditions where constancy and dimensional accuracy are required, the obtainment of surfaces with reduced roughness, thicknesses and allowances and the almost total absence of blowholes and inclusions.
It allows an excellent structural compactness, therefore it improves the mechanical characteristics and resistance to corrosiveabrasive environments /fluids and atmospheres. It is interesting for parts with surfaces that cannot be machined qualitatively and superficially, and excellent as cast. It is advantageous in cases where alloys with critical hardness and machinability, considering the reduced allowances and subsequent less laborious mechanical machining, in some cases superfluous. Better metallurgical integrity, excellent surface finish and good dimensional accuracy make the ceramic process highly elastic in use, allowing greater
design flexibility.
Normally this process is used to produce impellers for centrifugal pumps, impellers for compressors, diffusers for pumps, rotors for turbines, Pelton wheels, pelton blades, Kaplan blades, parts for the food industry, special pump bodies, nautical and agitator propellers, molds for forging, range, plastics, glass, die casting molds, dies and punches, extrusion dies, tube bending spindles, filter press plates, various pieces for the chemical, mechanical, naval and aeronautical industries
The models, conceptually of a traditional type, are built with remarkable accuracy and precision
