Physical non-stick pan with convex-concave structure, and manufacturing method thereof

Abstract

A physical non-stick pan with a convex-concave structure, and a manufacturing method thereof are provided. The physical non-stick pan includes a pan body, where the convex-concave structure is formed on an inner surface of the pan body, the convex-concave structure comprises a convex edge protruding from the inner surface of the pan body and a recess enclosed by the convex edge, and a physical non-stick layer is at least arranged on an inner surface of the pan body in the recess. In the convex-concave structure, the convex edge protects a non-stick layer arranged in the recess, reduces a direct friction between a spatula and the non-stick layer, and prolongs a non-stick effect of the pan body.
