Abstract
The invention provides a pan with a composite bottom, a manufacturing method of the pan, and a cooking utensil. The manufacturing method includes: preparing a pan body plate and a composite bottom plate; riveting or pressingly fixing the composite bottom plate on one side of the pan plate, stamping to form ribs on the pan plate, and allowing the ribs to protrude towards one side with the composite bottom plate and surround the composite bottom plate; performing stretch forming on the pan plate so as to manufacture the pan with the composite bottom. By the arrangement, the wall thickness of the position, in contact with the ribs, of the pan plate is increased by the ribs formed on the pan plate, during stretch forming for manufacturing the pan, material flowing at the composite bottom area in the ribs is weakened due to the increased wall thickness of the pan plate, deformation of the composite bottom area is reduced, and problems such as composite bottom raising caused by material flowing of the composite bottom area are solved.
