Manufacturing method of non-stick pot

The invention provides a manufacturing method of a non-stick pot, which comprises the following steps: firstly, printing ink patterns on one side surface of a single pot body sheet and drying; secondly, superposing and fixing the pot body sheets together by taking two sheets as a group by using a protective sheet, so that one side of the same group of the two pot body sheets, which are not printedwith the ink patterns, is stuck together and cannot penetrate liquid; thirdly, simultaneously carrying out spray etching on one side of the same group of the two pot body sheets which are wound together, and respectively printing thepot body sheets with the ink patterns through an etching machine to form concave-convex lines; then cleaning the ink on the surface of the etched pot body sheet surfaces, and then stretching and forming the pot; finally, spraying a non-stick coating and polishing the inner surface to remove the non-stick coating on the convex-convex surface of the non-convex surface.
