How Die Casting and Anodizing Give Aluminum Nonstick Cookware Color And Durability?

Aluminum nonstick pots have many advantages such as lightness, good thermal conductivity, and corrosion resistance, and are widely used in the kitchen. 

Today, let’s uncover the mysterious process from metal aluminum to non-stick pots.

1) Die Casting Process - From aluminum blocks to the basic shape of pots

Aluminum alloy is a very suitable raw material for die-cast pots due to its low melting point and high strength.

To make a die-cast aluminum pot, we need to heat the aluminum alloy to a molten state, and then inject the molten alloy liquid into a designed pot-shaped mold. Then use the die-casting machine to die-cast the shape of the pot. After cooling, trimming the pot is and finally form a complete pot.

Through this efficient die-casting process, aluminum cookware can be produced quickly and on a large scale with high dimensional accuracy and consistency, laying the foundation for subsequent surface treatment.

2) Anodizing - Giving colors and nonstick performance to the aluminum pots

Anodizing is the process of passing an electric current through an electrolyte to form an aluminum oxide film on the surface of aluminum. It can help improve the hardness and wear resistance of aluminum pots, extend the service life of pots, and give aluminum pots a unique color appearance, increasing their aesthetics.

First, we need to clean, decontaminate, and deburr the surface of the aluminum cookware. Then we electrolyze it to form an aluminum oxide film, and then use dyeing liquid to color the oxide film to form different color appearances. Finally, we seal it to improve the pot's anti-fouling ability.

Anodizing not just gives the aluminum pot strong durability, and makes it more attractive. In addition, since the hardness of the aluminum oxide film is very high, it can effectively improve the wear resistance and service life of the pot.

Since the pots are consumable products, the market for aluminum pot production is good. By using die-casting machines, the quantitative production of aluminum pots can be achieved to meet the ever-expanding market demand.
