Abstract

An improved mold assembly is provided for use in a thermo-forming press having a first and a second platen movably engageable there between. A first die member of the assembly is configured to be carried by the first platen. A second die member is configured to be carried by the second platen, and is constructed and arranged to mate in assembly with the first die member. Aa resilient member is disposed between one of the die members and an associated one of the platens. The compliant member is constructed and arranged to provide compliant engagement between the first and second die as first and second platens on which they are mounted, respectively, are engaged together to form a web of plastic material there between during a thermo-forming cycle.
