FIELD: foundry, namely manufacture of casting ceramic molds with use of investment patterns by electrophoresis process.
SUBSTANCE: apparatus includes electrolyzer connected with negative pole of electric current source; suspension for pattern connected with positive pole of current source. Suspension is provided with device for measuring mass of pattern and for turning off electric current source when mass of pattern achieves predetermined value. Formed envelopes have the same thickness.
EFFECT: possibility for making casting ceramic molds with similar mechanical properties.
