Abstract
A mold assembly for forming a component exhibiting a sealed interior, including 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. 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.
