摘要:
A process for making a polymer with ultra-high mechanical properties by subjecting it to a compressive force and a rotational force perpendicular to the compressive force in a contained geometry at a temperature near to but below the crystalline melting point of the polymer.

57 A straight-hydraulic mold clamping system for use in a molding machine has a bearing portion (5) for a rod (3) of a mold clamp cylinder (1) provided with a plurality of annular oil grooves (20, 30) within which an oil functions, and utilizes the rigidity of the rod so as to horizontally support a movable platen (12) and a molding die (13) attached to the movable platen in a cantilever manner and maintain the horizontality of the movable platen and the molding die.

An upright injection-compression pressing machine for the manufacture of information carrier discs, such as photograph records and video discs, comprises a mold ciamper assembly including a pair of stamper bearing molds movable relative to each other in a vertical direction close towards and away from each other, and an injector assembly mounted on the clamper assembly in alignment with the direction of the relative movement of the molds.
