In a method for producing a multilayered heat shield, which has a first metal layer and a second metal layer that has an insulating layer arranged between the metal layers, the metal layers are connected at the edge by a flanging. To produce the heat shield, the first metal layer, the insulating layer and the second metal layer are placed into a first pressing tool. This is effected in such a way that an edge portion of the first metal layer protrudes beyond an edge portion of the second metal layer. The insulating layer is set back from the edge portions of the first metal layer and of the second metal layer.

An apparatus and method are disclosed for the automated manufacture of a duct flange profile to make small duct fittings, including a transverse duct flange duct flange profile. The duct flange profile is directed to small part duct fittings with section widths up to about 16 inches in 20 to 26 gauge metal. The apparatus includes a bending head assembly having a drive roller, a pressure roller, an anvil and a bending leaf and a roll form assembly.

A method of forming a cast heat exchanger plate includes forming at least one hot core plate defining internal features of a one piece heat exchanger plate and at least one first set of interlocking features. At least one cold core plate is formed defining external features of the heat exchanger plate and at least one second set of interlocking features. A core assembly is assembled where each hot core plate is directly interlocked to at least one cold core plate. A wax pattern is formed with the core assembly with an external shell formed over the wax pattern. The wax pattern is removed to form a space between the core assembly and the external shell. The space is filled with a molten material. Once the molten material has solidified, the external shell and the core are removed.
