Dry forming process for purple clay porcelain

Abstract

The invention discloses a dry forming process for purple clay porcelain. The process comprises the following steps of: 1) crushing west clay and east clay to 80-120 meshes respectively, weighing the west clay and the east clay in a weight ratio of (5-6): (4-5), and mixing the west clay and the east clay uniformly to obtain clay powder; and 2) selecting an aluminum alloy die with proper shape according to the prepared product, fixing the aluminum alloy die on a hydraulic press, filling the clay powder into the die cavity of a lower die of the aluminum alloy die, and performing press forming under the positive pressure of 80 to 400 tons. Compared with the prior art, the forming process has the advantages that: a plastic forming blank or a grouting forming blank does not need to be prepared previously and then the forming process is performed, so the processes of taking the clay to forming in the purple clay porcelain making process are greatly simplified, the time of taking the clay to forming is shortened, the production efficiency is improved, the production cost is lowered, and the market competitiveness of an enterprise is effectively improved.
