I. Manufacturing Process of Enamel Mugs
Metal Base Shaping
- A metal base, commonly made of steel, is initially formed into the mug's shape. This can be achieved through stamping, where a flat sheet of metal is pressed into the desired form using a die, or spinning, a process that shapes the metal by rotating it while applying pressure.
Enamel Glaze Application
- The enamel glaze, composed of materials such as silica, feldspar, and metal oxides, is then applied to the metal base.
- There are several application methods:
- Dipping: The metal mug is submerged into a bath of enamel glaze, ensuring an even coating.
- Spraying: The glaze is sprayed onto the mug's surface using a spray gun, allowing for precise control over the thickness and coverage.
- Electrostatic coating: This method uses an electrostatic charge to attract the enamel particles to the metal surface, resulting in a uniform and efficient coating.
Firing
- After the enamel glaze is applied, the mug is fired at high temperatures, typically in the range of 750 - 850°C.
- During firing, the enamel glaze melts and fuses with the metal surface, creating a hard, smooth, and durable finish that is both decorative and protective.
