Abstract
An apparatus for molding articles free of seams and parting lines including a one-piece flexible mold which is deformable and which includes a rigid core member, and a vacuum pot which is used to cause the mold to expand radially outwardly to allow the molded article to be released. The core member may comprise a rigid central mandrel which is rigidly embedded in the bottom wall of the mold and which is hollow and includes ports such that a pressurized catalytic gas may be injected into the mold material to cause a bonding agent to set.
