    Abstract: A composition and process for the manufacture of shaped articles by injection molding of thermoplastic material and glass fibers. The process involves the heating and masticating of from about 20 to about 40 percent weight thermoplastic material in the form of a powder having a particle size from about 30 to about 200 mesh, with from about 40 percent to about 60 percent weight of the same thermoplastic material in the form of pellets having a maximum dimension of about 1/16 inch to about 3/8 inch, together with from about 20 to about 40 percent weight of glass fibers having a maximum length of about 1/16 inch. The mixture is then injection molded to produce the article.
