发明名称 Dry-type powder pressing method and apparatus.
摘要 <p>Powder (14) is filled in an axially elongate powder filling space (1) defined in a flexible pressure tube (25, 225, 245, 325, 525), and the pressure-bearing surface of the flexible pressure tube (25, 225, 245, 325, 525) is pressurized with a pressurizing fluid (7), from a wall portion of the pressure tube (25, 225, 245, 325, 525) which corresponds to a localized region of the powder filling space progressively toward another wall portion of the pressure tube (25, 225, 245, 325, 525) which corresponds to an end of the powder filling space (1), until the pressure-bearing surface of the pressure tube (25, 225, 245, 325, 525) is pressurized in its entirety, for thereby compacting the powder (14), in the powder filling space (1). Therefore, air in the powder (14) is progressively squeezed toward the end of the powder filling space (1) where the air can be discharged out. No air thus remains trapped in the powder (14), and a formed product is prevented from being damaged, which enables to produce elongate products.</p>
