The mold halves are reopened, with at least one of the shells being subsequently reoriented such that the first and second half shells are arrayed in opposing fashion with perimeter extending edges of each half shell arranged in contact with one another. Additional steps include reclosing the mold halves and subsequently forming a second perimeter extending material in contact with the contacting perimeter extending edges in order to bond the half shells together, upon which the mold halves are reopened and a completed component removed. ## Claims ### Claim 1 A method for forming a component exhibiting a sealed interior, comprising the steps of: providing first and second mold halves; forming first and second half shells of material within cavities defined within each of the mold halves and upon mating the mold halves together in a first closed mold configuration; opening and subsequently reorienting at least one of the shells or mold halves such that the first and second half shells are arrayed in opposing fashion with perimeter extending edges of each half shell arranged in contact with one another; said steps of opening and reorienting further including each of rotating the first mold half to reposition the first half shell, in combination with employing a pick-and-place mechanism with the second mold half for transferring the second half shell to a further cavity within the second mold half which opposes the first mold half; reclosing the mold halves and subsequently forming a second perimeter extending material in contact with the contacting perimeter extending edges in order to bond the half shells together; and reopening the mold halves and removing a completed component. ### Claim 2 (depends on 1) The method as described in claim 1, the step of rotating the first mold half further comprising supporting upon a rotary die slide platen. ### Claim 3 (depends on 1) The method as described in claim 1, further comprising the step of configuring multiple configurations within each of the mold halves, the multiple configurations including at least one cavity and one seating projection for creating successive first and second half shells of material in each first closed mold configuration. ### Claim 4 (depends on 1) The method as described in claim 1, the first and second material forming steps further comprising injection molding operations for introducing a thermoplastic material in flowable form between the mold halves. ### Claim 5 (depends on 4) The method as described in claim 4, further comprising the step of configuring channels within and between the mold halves in order to deliver the thermoplastic material. ### Claim 6 (depends on 1) The method as described in claim 1, further comprising the step of forming said second perimeter extending material so as to exhibit an angled lip edge for bonding overlapping locations associated with the mating edges of the repositioned half shells. ### Claim 7 (depends on 3) The method as described in claim 3, the step of forming the first and second half shells further comprising forming the shells in first and second selected pairs of aligning cavity defining configurations established between the mold halves, while concurrently forming the perimeter extending material about a pair of previously formed and reoriented mold shells arranged with a third selected pair of aligning and cavity defining configuration.
