A New Method of Screw Extrusion Molding Pressure

Abstract

This paper research on the screw extrusion technology，using a new method for improving the quality of explosive，combined with the Principle of quasi-isostatic molding technology，by loading pressure at the extrusion outlet. By simulating the process that the explosive forming in the mould ，test whether the new method meets the basic conditions of quasi-isostatic molding technology，compare advantages and disadvantages under technical specifications with traditional screw extrusion technology. Results showed that new method not only conforms to quasi-isostatic pressing conditions，but also can improve the quality of medicines compared with traditional method.
