Abstract
The invention provides a novel thermoplastic molding process useful in the manufacture of hollow, deformable thermoplastic articles such as hollow doll heads. In the process of the instant invention, a parison is formed at a first injection station and is transferred to a blow mold station. At the blow mold station, the parison is transformed into a hollow, deformable thermoplastic article through application of a vacuum and gas injection. Articles made by the process of the instant invention have a highly realistic appearance and texture.
