초록

A powder compaction method in which a powder p is filled by air tapping or other suitable method into a mold 1 , then while the mold 1 being filled with the powder, the powder particles are bound with each other without application of force from outside the mold to form a compact C, and then the compact C is taken out from the mold 1 . This method produces a variety of shapes of the compact far greater than in conventional methods, and net shape manufacturing of products with complex shapes is made possible by this method. Because this method uses far le...

청구항

1. A method for producing a sintered article from a green compact, comprising:filling a mixture comprising powder particles and a binder into a mold by air tapping,binding the powder particles to each other without application of force from outside the mold after the mold is filled with the powder to form a powder compact,driving the binder off from the powder compact to form the green compact,removing the green compact from the mold, andsintering the green compact to produce the sintered article. 2. The method of claim 1, in which the binding of the pow...
