MOLDED GAS BARRIER PARTS FOR VACUUM INSULATED STRUCTURE

Last updated:

Abstract:

A method of fabricating a vacuum insulated appliance structure includes molding a first layer of a first polymer material. A second layer of a second polymer material is molded to (e.g. over) at least a portion of the first layer, and a third layer of a third polymer material is molded to (e.g. over) at least a portion of the second layer to form a first component. At least one of the layers is impervious to one or more gasses. One or more additional components are secured to the first component to form a vacuum cavity. The vacuum cavity is filled with a porous material, and the vacuum cavity is evacuated to form a vacuum.
