摘要： A method and apparatus for the cross-hole pressing of cutting inserts (10) is disclosed whereby a green part (110) is fabricated using metallurgical powder (260) and an opening (25) is imparted within the green part by placing the metallurgical powder about an oval-shaped core rod (235). Using a press (200) with a uni-axial press motion, a core rod is placed within the cavity (210) of a mold and metallurgical powder placed around the core rod and thereafter compressed to form a green part. The subject invention is also directed to an article formed utilizing such a process and the uni-axial press used to produce such an insert.

摘要： When producing a sinterable ceramic or metallic body (15), a tool is used which can be assembled from two or more tool parts (19, 24). A moulding space (F) corresponds to the shape of the body. One tool part (24) is produced using a wet composition which comprises solvent, heat-conducting particles and material which is readily worked and form-stable in solidified form, for example plaster. The material is caused to solidify in a binding function in which the solvent is eliminated and pores thereby arise in the solidified material. The injection moulding composition is injected into the space (F) using a low or medium compression moulding pressure and heat which arises due to the injection into the space is conducted away by means of the said heat-conducting particles in the solidified material. Any gas or air which is trapped in the space is conducted away through the pores in the solidified material.

摘要： Method and device for production of powder metal bodies comprising:

introducing powder material (4') in a compacting chamber (4) in a hollow die (1), compacting the material in mainly axial direction in the compacting chamber by urging a first punch (2), axially into said compacting chamber,
advancing said first punch (2) further into said compacting chamber for further compacting the powder material and imparting upon the die plate (1) a biasing tension, causing the edge portion of the die opening to move under increasing tension in the same direction as the first punch (2), thereby causing opening radial size reduction,
causing axial compression also in a direction opposed to that by the first punch (2) by a second punch (3), arranged to move opposed relative the die (1) as compared to that of the first punch (2), and
retracting the first punch (2) axially, thereby relieving the hollow die from its biasing and regaining initial form, thereby simultaneously expelling the compact thus formed.
