A method of forming a vacuum insulated refrigerator cabinet, the method comprising providing first and second sheets of material. The first sheet of material is thermoformed over a first forming tool forming a first intermediate structure. The first intermediate structure is then thermoformed over a second forming mold to create a second intermediate structure. The second sheet of material is then sealing connected with the second intermediate structure forming an annular space. A vacuum is created in the annular space creating a vacuum insulated cabinet...
1. A method of forming a vacuum insulated refrigerator cabinet, the method comprising: providing first and second sheets of material comprising at least a first layer of thermoplastic material that is at least partially permeable to oxygen, nitrogen and water vapor, and a second layer of material that is substantially impermeable to oxygen, nitrogen and water vapor;heating at least a portion of the first sheet of material to a temperature at which the first sheet of material can be plastically deformed;utilizing a first forming tool to deform the first s...
