PROCUREMENT TECHNIQUE TO OBTAIN SHELL MOULDS BY CATAPHORESIS METHOD Russian patent published in 2008 - IPC B22C9/04 

FIELD: metallurgy.

SUBSTANCE: remainder of electrophoretic suspension of the similar initial substance are to be dried until their remaining humidity equals 0.5-1% and then grinded. In the mixture obtained, water must be added so that the suspension can become sufficiently viscous; thereafter, it must be stirred for some 30-40 minutes. The suspension resulted can be used for forming phoretic residue at the electricity-conducted model to which power supply is then applied.

EFFECT: achieves reduction in costs of the moulding form.
