Starting with the manufacture of clay dough. The tun and hydraulic pumps mix all their components.
The mixture goes through extrusion equipment, and is ready to be sent to the factory.
The operator checks if the dough strength is within the expected range.
At the ceramics factory, the designer creates models of final pieces that will serve as a basis for making the molds.
With the model ready, the matrix is made. The matrix is made with very rigid plaster. And it is from the matrix that the production molds are manufactured.
Each mold supplies 5 pieces per day. It's a pretty slow process.
The operator feeds the mold with slip, or slurry. Turning the lathe spreads the mass internally. So she makes the shape of the mold. The excess is removed and reused.
On larger parts, the mold is made in more parts.
Depending on the part, you still need to trim some parts.
With the pieces already trimmed, they undergo the first burning or biscuit burn. Through a mat, the pieces pass through this oven, where the entire journey takes about 5 hours. In this way the pieces come out completely dry.
The quality of the ceramic is determined by the clay used at the firing temperature.
After the products have cooled down, it is time for vitrification. The operator immerses the pieces in a liquid solution that will give the color, texture and shine.
Going to the end, the products go through another burn. They pass through the kiln tunnel for about 12 hours.
