Clay, wet sand casting uses clay as the main raw material, plus an appropriate amount of water as a binder to make sand molds. Afterward, it is molded and poured in a wet state to obtain the finished product. Its strength mainly depends on the clay slurry. The process factors mainly include the amount of clay and water.
Clay Sand Casting Part
The advantage of clay sand casting
(1) The raw material resource is abundant and cheap, so its cost is low.
(2) The clay wet sand produced during the production process can be recycled after treatment to avoid waste.
(3) The casting cycle is short and the casting efficiency is high.
The clay sand casting part process
The old sand falls on the high-speed rotating regeneration plate through the quantitative device, and is thrown to the surrounding wear-resistant ring under the action of centrifugal force. The repeated friction and collision between the sand grains and the wear-resistant ring and between the sand grains makes the adhesive film on the surface of the sand grains After being removed, the regenerated sand falls from between the wear-resistant ring and the regeneration disc. At the same time, the fan on the same axis as the regeneration disc blasts upwards to form a strong air flow to boil, winnow, and remove adhesive film and dust on the falling sand. , to obtain recycled sand that meets the process requirements. After the old sand is processed, the content of dead clay is low, the amount of new sand added is small, the mixed molding sand has high wet pressure strength, good fluidity and air permeability.
