Abstract: A method and apparatus for manufacturing a composite article by use of a mold core and a cavity block and wherein a skin and insert are placed in the mold cavity and foam precursors are poured into the mold cavity to complete the article includes a process in which a series of part replicas are formed and used to cast thermally stable liners that are carried by the mold core and mold cavity. The thermally stable liners have low melt temperatures and can be reused and recast following wear during the molding process. The liners are made from material which has low shrinkage and expansion rates to define a mold assembly that will produce repeatable parts.
