Abstract: A molding method for moldable bio-substance materials comprises crushing the bio-substance materials into an incompact state, and then extruding and molding the same. There is at least a wedged extruding cavity is formed between the extruding head and the extruding surface of the molding die. The movement between the extruding head and the extruding surface of molding die is a differential speed movement, and the particles of the materials are extruded between these two surfaces and are grinded, twisted up, stretched, flaked, and then extruded to the small end of the wedged extruding cavity, and further into the molding cavity of molding die to be molded therein. The molding method and equipment of this invention can give the molded product certain strength and water-fastness without using any chemical binders. It is convenient for storing the product and keeping the product in a functional state, and thus it minimizes the cost for fabrication, transportation and storage.

Abstract: The present invention is an extrusion molding cavity and a molding machine for loose fabricable biomaterial. The molding cavity comprises molding section and an expanding section in sequence from the inlet side to outlet side of it. A guiding contracted section is located at the inlet side of the cavity and at side of the molding section. The inlet area of the guiding contracted section is larger than the molding section's. The molding unit comprises at least a shaping mold comprising the extrusion mold cavity, an extrusion head driven by power, and an extrusion surface between said extrusion head and shaping mold, wherein the large end of the wedge-shaped extrusion cavity provides a material inlet, and whereby a grainy material is intruded into the shallow end of said guided contracting segment from the large end of the wedge-shaped extrusion mold cavity, compressed, and enters the molding segment.
