Abstract
PURPOSE: To obtain a resin molding excellent in the surface smoothness, mechanical property and dimensional stability by stamping crystaline polyester resin above a specified level of cross-linking at the melting point to the decomposition temperature.
CONSTITUTION: A crystaline polyester resin cross linked at a rate of 30% or more, preferably 45% or more, is molded by stamping above the melting point but below the decomposition temperature. If the cross linking rate of the crystaline polyester resin is less than 30%, the shape of the material can not be maintained properly when heated above the melting point in the stamping molding. This not only makes it hard to transfer the material to the mold and hampers the improvement in the smoothness of the molding surface but also render the mechanical property and the dimensional stability of the molding unsatisfactory. Thus, such a condition of the material is unpreferrable and should be avoided.
