What is the manufacturing process of a frying pan?

The manufacturing process of frying pans varies depending on the material. The following is a detailed explanation of the manufacturing process of frying pans made of common materials:

1. Iron frying pans

• Material selection and smelting ‌
Select high-quality iron ore and smelt it into molten iron at a high temperature of more than 1500℃‌.

• Mold preparation and casting ‌
Use a sand mold or a metal mold to pour the molten iron into the mold to form it.

• Cooling and demoulding ‌
Wait for the molten iron to cool naturally before demoulding to form the prototype of the pot body.

• Grinding and polishing ‌
Grind the pot body with a grinding wheel to remove burrs and polish the surface.

• Hammering and quality inspection ‌
Some processes require manual hammering to increase the density of the pot body, and finally conduct quality inspection.

• Oiling protection ‌
Apply a layer of oil to protect the pot body from oxidation.

2. Aluminum frying pans

• Aluminum block smelting ‌
Melt the aluminum block into aluminum water at a high temperature of more than 660℃ ‌
• Die casting ‌
Use a die casting machine to press aluminum liquid into the bottom of the pot, and quickly solidify it under high pressure ‌.
• Edge processing ‌
Workers knock off excess aluminum and polish the edge of the bottom of the pot to make it smooth ‌.
• Surface treatment ‌
Perform anodizing treatment to enhance corrosion resistance and wear resistance ‌.
• Quality inspection and packaging ‌
Inspect the quality of the pot body and then pack it for shipment ‌.

3. Stainless steel frying pans
• Plate stamping ‌
Press the stainless steel plate into the shape of the pot body ‌.
• Welding and grinding ‌
Weld the pot body and handle, and perform surface grinding ‌.
• Polishing and quality inspection ‌
Polish the surface of the pot body and check for defects ‌.
• Packing and shipment ‌
Package and shipment ‌
After completing quality inspection ‌.

4. Handmade frying pans
• Die forging ‌
Use a machine to punch out the prototype of the pot body ‌.
• Hand hammering ‌
The craftsman hammers the pot body by hand to make it more dense and have a unique texture ‌.
• Grinding and polishing ‌
Grind and polish the surface of the pot body. ‌
• Quality inspection and oiling ‌
After quality inspection, oil the pot body to protect it. ‌
V. Modern automated production line ‌
• Raw material processing ‌
Melting the raw materials (iron, aluminum or stainless steel) into liquid. ‌
• Die casting or stamping ‌
Using a die casting machine or a stamping machine to form the pot body. ‌
• Surface treatment ‌
Grinding, polishing or coating ‌
• Quality inspection and packaging ‌
After automated quality inspection, packaging and shipment. ‌
VI. Special processes (such as nitriding treatment) ‌
• Nitriding treatment ‌
Nitriding the pot body at high temperature to enhance rust resistance and durability ‌
• Quality inspection and packaging ‌
After quality inspection, packaging and shipment. ‌
Through the above processes, frying pans of different materials can be efficiently produced and meet user needs ‌.
