Impellers for hydraulic torque converters were conventionally produced by sand mold casting. Specialists at ZAO Litmashdetal have proposed to cast impellers in a metal mold. By their quality produced cast impellers ore not inferior to those made abroad. The new process allowed: reducing the casting mass by 2.5 times, increasing the process output capacity by about 2 times, lowering the rejects.
