Production process
Learn more about the manufacturing process of our products.
WEIGHING
Raw materials, such as clay, kaolin, quartz, phyllite and pegmatite among others, are tested and then weighed in exact quantities to make the ground mixture.
GRINDING
Water is added to the raw materials which are ground for 20 hours, and as a result the barbotine or slip is obtained.
CASTING
Plaster molds are filled with barbotine, that acquires the mold shape in 1 hour and a half, resulting in the raw piece. Always concerned with quality, Celite once again became a pioneer in Brazil by introducing the greatest technological advance in the sector: the die casting. This mechanized casting process has numerous advantages such as: rationalization of space and work, productivity and, above all, the highest final quality of the product.
ENAMELING
After a drying period in special greenhouses, 3 layers of enamel are applied to the pieces with a compressed air spray gun.
FIRING
Pieces are fired for approximately 13 hours in tunnel kilns at a temperature of 1,220ºC/2,228ºF.
CLASSIFICATION
All products are rigorously tested and classified according to international quality standards. Functional tests are also performed with normal volume of water to check if the product is compliant with the standards of ABNT (Brazilian Association of Technical Standards) and the operating standards required by the international market. Aesthetic defects such as blisters and holes, deformations, enamel failures, stains or dirt from burning are not tolerated. If the quality standard is not achieved, the product is discarded to guarantee the final quality. For all these reasons, Celite holds the Quality Seal of the Canadian Association for Standardization and the International Association of Officers in Mechanics and Hydraulics.
Our entire production process is based on the reutilization of the products that are discarded due to imperfections, by returning them to the beginning of the production process. In addition, the water used in the production process is collected, treated and reused in the production.
