How are Non-Stick Pans Made
Non-stick pan is one of the most common and popular cooking appliances. Non-stick pans, as the name states, do not allow the food to get stuck at the base of the pan while cooking and are pretty easy to clean and maintain.
Apart from being non-stick, the other healthy option of using non-stick pan is that significantly less oil or fat is required to fry any item.
Materials used to make a non-stick pan
The surface of a non-stick frying pan has a coating of polytetrafluoroethylene, and Teflon is a reputed brand of this.
However, several other layers are used to make a non-stick surface, and the safest coatings are enameled or seasoned cast iron, anodized aluminum, and superhydrophobic coatings, and so on.
How non stick pans are made
• To make a non-stick frying pan, metals that are heat conductive are mainly used. The metal is then transformed to a liquid state at a very high temperature. For casting, a robotic ladle is used to scoop the molten metal. The two-part dye is used to transform the molten metal into a frying pan.
• The liquid metal is then forced into the dye by the robotic ladle. The casting under tremendously high pressure helps give a precise shape. Then the shape is made perfect by computerized equipment.
• Human touch is required to round off the pan’s rim or edge to some more extent. The non-stick pans then get various thicknesses and different sizes. The pans are then shifted to a sandblasting room so that the non-stick pans get a ceramic coating.
• These non-stick pans are placed on a spinning wheel where three different types of molten powders are sprayed evenly on the pan. Those are then scrubbed to remove the residues.
• A coat of a mixture of several chemicals and diamond particles are applied on them. Diamonds help to increase the ability of the frying pans to conduct heat. Because of these diamond particles’ presence, the food doesn’t get stuck to the base of the non-stick pan.
• Different types of coatings are then sprayed evenly on the surface of these pans. Finally, a non-stick coating is then sprayed, which helps in binding the other layers of coating.
• The non-stick pans are then taken to the furnace to bake the coatings to avoid getting peeled off.
• Finally the handles are attached to the sides of the non-stick pans.
The selection of a high-quality non-stick pan material is very essential.
The topmost layers of cheap and average quality non-stick pans tend to peel off after several usages because of being exposed to very high temperatures.
One can take several preventive measures to avoid such scenarios, like not exposing an empty pan to the heat for quite long and using spatulas made of wood and plastic to cook in a non-stick pan to avoid scratches on the pan in the long run.
