Flexible foaming process for producing thermally insulated articles

A flexible discontinuous process produces a series of at least two articles containing thermally insulating polyurethane foam from at least three streams (A), (B) and (C). The process involves mixing the at least three streams with different mixing ratios and injecting the mixture into cavities of the articles. A production unit can be used for performing this process.

Method of fabricating 3D vacuum insulated refrigerator structure having core material

A method of fabricating a vacuum insulated refrigerator structure includes positioning a first barrier film in a female mold cavity. Porous filler material is positioned on the barrier film, and a second barrier film is positioned over the porous filler material. A male mold is brought into contact with the second barrier film to deform and compress the porous filler material into a 3D shape. A vacuum is formed between the first and second barrier films, and the first and second peripheral edge portions are sealed together to form a vacuum insulated core. The vacuum insulated core may be positioned between a liner and a wrapper to form an insulated refrigerator cabinet, door, or other vacuum insulated component.
