The method of production of these dishes is in the same way that it is currently used in developed countries to produce complex car and aircraft parts. The production of these dishes is done with advanced Die Cast technology. In this method, high-pressure melted aluminum alloy is injected into steel molds. After cooling, the piece is removed from the mold and the aluminum surface is mirror polished.
The aluminum piece is then subjected to a high-pressure sandblasting process until the aluminum surface reaches a rough surface on a micron scale. This surface roughness creates the right conditions for a strong physical bond between the aluminum and the Teflon or ceramic coating in the next step. After sandblasting, the parts are placed on the conveyor of the automatic spraying line and without the intervention of the hand and with the help of modern technology, they are exposed to spraying non-stick Teflon or ceramic materials and different colors in one or more layers with uniform thickness.
