Abstract:
The invention relates to a molding compound for producing molded parts by means of a powder injection molding process, comprising at least one inorganic powder and a binder system comprising at least one optionally polar-modified polyolefin. The binder system further comprises at least one wax. The invention further relates to a method for producing a molding compound for a powder injection molding process, wherein, in a first step, a mixture of at least one inorganic powder, at least one polyolefin, and at least one wax is melted and homogenized, wherein at least one polyolefin and/or wax is polar-modified and, in a further step, the melt is solidified and formed.
Abstract:
An ultra hard alloy is a hard material with a high degree of toughness. Small amounts of various materials are added to achieve these properties. One such material is vanadium carbide (VC). However, a crushed carbide raw material has a large grain size, meaning the properties of a product cannot be improved uniformly. Vanadium trioxide (V 2 O 3 ) was substituted for a carbide as one of the structural raw materials for a material used in producing a tool such as a hob. Because vanadium trioxide is softer than vanadium carbide, it can be readily converted to fine grains in the ball mill mixing process performed during raw material preparation. As a result, the effects of the uniformly dispersed vanadium trioxide results in improved hardness for the sintered ultra hard alloy.

A method for producing a soft magnetic powdered core comprises a mixing step for forming a raw powder by adding a thermoplastic resin powder to a soft magnetic powder and mixing them, a compacting step for forming a compact by compacting the raw powder into a predetermined shape, a melting and setting step for the resin in which the resin of the compact is melted by heating to at least the melting point of the thermoplastic resin and the melted resin is set by cooling to a room temperature, and a crystallizing step for the resin in which the set resin is heated to not less than the exothermic onset temperature and not more than the endothermic onset temperature, which are measured by DSC analysis of the thermoplastic resin, and is cooled to a room temperature.
Abstract:
The present invention relates to a method and an apparatus for forming flakes, especially metal flakes. The method comprises producing a heated stream of molten material, feeding the stream in a substantially vertically downward direction, receiving the downwardly directed stream and forming flakes therefrom, and effecting a change in the temperature of the stream subsequent to the production thereof whereby flakes of a desired thickness are obtained. The present invention is applicable to any metal which melts when heated and is capable of being formed into flakes. Examples of metals are Al, Cu, Mo, V, Ag, Cr, Zr, Nb, Ni, Fe, Co, Ti, Au, Pd, W, Hf, Rh, Ir, Pt, Cd or alloys thereof, such as chromium-nickel, iron- nickel, iron-chromium and nickel-cobalt, wherein Cu, Ag, Ti, or Al, or alloys thereof are preferred and Al, or Ag, or alloys thereof are most preferred.
