Abstract: An apparatus for producing a green compact includes a circuit that circulates die assemblies, each of which contains a rubber mold having rubber in at least its side portion. The apparatus also includes a high density filling device that has a feeder for feeding powder into the rubber molds; a pusher or a vibrator or both a vibrator and a pusher; a die press machine configured to impart a compaction force sufficient to produce the green compact to each of the circulating die assemblies in succession; and a device for removing the green compact from each rubber mold. The high-density filling device, the die-press machine and the removing device are successively arranged along the circuit. Each of the circulating die assemblies has sufficient structural integrity to withstand the compaction force because all structure necessary to withstand the compaction force is present in the circulating die assemblies.

Abstract: A method for forming a coating on at least one part to be coated has the steps of agitating a mixture including (i) the at least one part to be coated, (ii) a material that forms an adhesive layer on the at least one part to be coated, (iii) impact media, and (iv) multiple compositions of powder material; and fusing at least one of the multiple compositions of powder material.

Abstract: Methods and apparatuses for producing a powder compacts are disclosed. A powder compaction apparatus includes a recess formed by die and a lower punch inserted into the die. The recess is loaded with rubber mold provided with a cavity shaped according to the desired configuration of the compact. Subsequently, the powder is packed in the cavity of the rubber mold, and an upper punch is placed on die to press the rubber mold with powder in the space formed by the die, the lower punch and the upper punch, thereby producing a powder compact.

Abstract: Powder-content of a powder-coating is enhauced. Powder material forms a skeleton structure. The clearances are filled with resin. The coating comprises a resin layer which bonds the power-compacted layer to the parts or any underlying powder-compacted layer. The work pieces on which a resin film may be preliminarily formed, is subjected to vibration or stirring together with the powder material and means for mediating the formation of the coating, which eans is of substantially smaller size than said work pieces and greater size than said powder material, as well as with or without the resin, to vibration or stirring in a container.

Abstract: Green compacts for sintered ceramic bodies and for sintered permanent magnets are produced by first preparing outside a die press machine a mold which contains a rubber portion in at least a side portion. The mold cavity is then filled with the fine powder which is to form the compact to a density which is at least 1.2 times the natural filling density of the powder. The filled rubber mold is then placed in the die press machine and compacted in the die press machine to produce the green compact. The natural filling density is obtained by allowing the powder to fall from a powder pan into the rubber mold until the powder reaches the top of the rubber mold, where the distance from the powder pan to the bottom of the rubber mold is 3.7 times the depth of the cavity of the rubber mold.
