Abstract

PURPOSE: To obtain a molded high polymer article having improved elasticity and transparency with increased sealing effect and easy selection of extrusion ratio, by solid extrusion of a high polymer material under hydrostatic pressure, using a highly plastically deformable metal as an extrusion pressure medium.
CONSTITUTION: The cylinder 2 of the high-pressure vessel 1 filled with the high polymer material 5, an extrusion material, and the highly plastically deformable metal 7 filled in the clearances between the material 5 and the plunger 6 and between the material 5 and the inne wall of the cylinder 2 are heated to the extrusion temperature. After the cylinder 2 and the die 4 are heated to given temperatures, a given pressure, preferably 500W5,000kg/cm2, is applied to the head of the plunger 6 to extrude the material, thus giving an molded article extruded from the tip of the die 4. Lead, tin, magnesium, zinc, bismuth, aluminum, etc. may be cited as the highly plastically deformable metal.
