Method of manufacturing a pan and non-stick pan

A method of manufacturing a pan, comprising:

• S1, preparing a roll of stainless-steel plate;
• S2, feeding the stainless-steel plate to a roller with a convex grain for rolling to forma pattern with a concave and convex structure on a side of the stainless-steel plate, wherein the pattern comprises ribs and grooves, the stainless-steel plate enters into the roller in a entering direction with an angle formed between the entering direction and a horizontal line, and the stainless-steel plate exits from the roller in a exiting direction with an angle formed between the entering direction and a horizontal line;
• S3, punching the rolled stainless-steel plate to form a shape of a pan body, wherein the pattern is located on an inner surface of the pan body after punching;
• S4, compounding a bottom of the pan body obtained after punching with a uniform heating layer and a heating layer in sequence;
• S5, sandblasting part or all of the inner surface of the pan body to form a rough surface on the inner surface of the pan body;
• S6, spraying the sandblasted surface in the pan body to form an anti-stick coating on the inner surface of the pan body;
• and
• S7, polishing the sandblasted or sprayed surface in the pan body to remove the coating on a top surface of each of the ribs, so as to expose stainless-steel on the top surface of each of the ribs.
