A cooking vessel includes a vessel body having a partially coated, textured stainless steel inner surface having a plurality of ribs rising above recesses having bottoms covered with a non-stick coating. The ribs have uncoated tops and sides that are separate from the bottoms of the cavities. The sides connect the tops to the bottoms. The tops rise above the non-stick coating covering the bottoms. According to the invention, the non-stick coating rises over the sides from the bottoms towards the tops without exceeding the height of the tops, and the bottoms and the sides have a rough surface under the non-stick coating. Also included is a method for producing a cooking vessel.

A frypot of a commercial deep fat fryer includes a foam deck and a front wall that is a downward extending vertical face of the frypot. The foam deck and the front wall are formed by sheet metal that has a radius bend between the foam deck of the frypot and the front wall. The radius has a bend radius of between 0.25 inches and 1.5 inches.

A checkered composite plate comprises a basal plate and a metal mesh; the material of the basal plate is aluminum; the metal mesh is embedded at the upper end of the basal plate and fixedly connected with the basal plate; the upper end of the metal mesh extends to the upper part of the basal plate; and the metal mesh forms raised checkers above the basal plate. In the checker composite plate of the present invention, the metal mesh is compounded on the upper end of the basal plate made of aluminum, so that the surface hardness of the aluminum basal plate is enhanced, thereby solving the defect that the aluminum basal plate is soft and not wear-resistant, solving the defect that the common composite plate is easy to deform when heated due to different stress of different materials.

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.

Cookware surfaces of metal, such as aluminum, may include a nonstick coating and embedded hard metal mesh. The mesh protects the nonstick coating between interior regions within the mesh from being cut or abraded by knives and other tools.

The profile shape of the vessel body and of handle portion is formed from a single sheet of metal to create a flat by cutting, stamping or blanking. An opening is created in the handle portion to reduce heat propagation. The shape of the pan body is formed by spinning with the flat handle portion. The handle is formed by creating three-dimensional contours in the handle portion of the blank. The neck portion has a flat section adjacent the pan body followed by sections of different curvature. One section of the neck portion has a deeply curved cross-section. That neck portion transitions to the hand grip portion which has a reduced curvature, particularly toward the unattached end of the handle. The neck portion may have a W cross sectional shape. The handle grip portion may have a U shaped cross-section for comfort.

A method for producing a pot-shaped component from a flat blank. The method comprises the following steps: a) shaping the flat blank in at least one deep-drawing step to form a pot-shaped raw component having a substantially flat bottom area and a circumferential frame, and b) shaping the pot-shaped raw component in a tool having a conically tapered die that applies shear to the circumferential surface of the frame in the axial direction against the conically tapered die. In step b), the bottom area is clamped between an ejector and a hold-down mechanism and the conically tapered die surrounds the bottom area of the raw component radially on the outside and extends in a diameter-reducing manner in a tool stroke.
