An apparatus and system is disclosed for fabricating refrigeration cabinets of the type including an outer shell and inner shell separated by an insulating medium, such as polyurethane foam. The inner and outer shells are each formed of a plurality of plates which, according to the invention, are maintained in their respective relative positions long enough to permit the insulating medium forming components to be introduced therebetween and to cure and adhere to the plates so as to thereafter maintain the plurality of plates in their predetermined relative positions as an integral cabinet without the need for prior securement. A novel thermal insulating member is also disclosed which extends along the forward marginal portions of the inner shell to prevent heat transfer between the inside of the refrigeration cabinet and the outside atmosphere during operation, while simultaneously maintaining electrical wires connected to the electrical system of the cabinet, or tubing for fluids or gases depending upon the installation in secured and hidden locations. Novel methods and systems are also disclosed for fabricating general purpose cabinets as well as refrigeration cabinets.

An apparatus for fabricating refrigeration cabinets of the type including an outer shell and an inner shell each formed substantially of a plurality of plate members, said inner shell being separated from said outer shell by a thermal insulating foam, which comprises: (a) a first mold fixture for receiving and supporting a plurality of prefinished plate members in a predetermined arrangement forming the outer shell, said outer shell having a plate member defining a rear outer wall and four plate members extending substantially perpendicular to said rear outer wall plate member in end to end relation therewith about the periphery thereof to form respectively, a top outer wall, a bottom outer wall and two side outer walls, said outer shell having positioned therein an inner shell formed of a plurality of prefinished plate members, said inner shell plate members forming a rear inner wall and four plate members extending substantially perpendicular to said rear inner wall plate member along the periphery thereof, the dimensions of the rear inner wall plate member being less than the corresponding dimension of the rear outer wall plate member such that the inner shell and the outer shell define a space therebetween for reception of polymerizable thermal insulating foam forming components therein, said inner shell having extending along the forward peripheral portions, substantially non-heat conducting means to form a thermal barrier between the inner shell and the atmosphere outside said inner shell, said substantially non-heat conducting means including a bridging portion dimensioned, positioned and configured to extend across the space defined between said inner and outer shells at the forward marginal portion thereof, the end of said bridging portion distal from said inner shell being in contact with the forward peripheral portions of said outer shell, and said first mold fixture including a plurality of upright plate members, at least two of which are movable and lockable to spaced positions corresponding to the respective outer dimensions of said outer shell, said first mold fixture plate members being of sufficient strength to restrain movements of said outer shell plate members in outward directions; (b) a second mold fixture movable from positions into and out of said first mold fixture, said second mold fixture having main support means having a plurality of downwardly extending plate members, at least two of which are movable and lockable to relative positions corresponding to the respective dimensions of said inner shell plate members, said second mold fixture plate members being of sufficient strength to restrain uniformly, inward movements of said inner shell plate members; (c) at least one foam gun for dispensing polymerizable thermal insulating foam forming components which react to form a polymerized thermal insulating foam within the space between the inner and outer shells, the dispensing portion of said foam gun being positioned for insertion and removal through an aperture defined by at least one of said upright plate members of said first mold fixture and also through an aperture defined by the corresponding plate member of said outer shell substantially in alignment with said first mentioned aperture such that the dispensing portion of said foam gun is positionable within the space defined between said inner and outer shells; and (d) means for supplying said polymerizable thermal insulating foam forming components and for controlling the amounts and rates of said components to said foam gun for dispensing into said space defined by said inner and outer shells said components necessary to form, upon setting, a polymerized thermal insulating foam, to substantially fill the entire space therebetween, said polymerized thermal insulating foam being of the type which expands during polymerization and which adheres to the plate members defining the inner and outer shells, the support members of said first and second mold fixtures being of sufficient strength and having continuous surfaces to maintain the corresponding respective contacting plate members of said inner and outer shells in a correspondingly substantially flat condition against the forces provided therebetween by expansion of said polymerized thermal insulating foam during polymerization, said bridging portion of said substantially non-heat conducting means extending across the forward portion of said space defined by said inner and outer shells and being positioned to prevent outward expansion of said thermal insulating foam during polymerization such that upon final setting, said thermal insulating foam adheres to the respective plate members of said inner and outer shells and retains them in their respective relative positions thereby substantially avoiding the need for other securing and retention means and final finishing step.
