Abstract
A powder pressing method includes laterally moving a dispensing plate and a base plate disposed under the dispensing plate from a pressing position to a dispensing position, laterally moving the base plate back to the pressing position while the dispensing plate remains in the dispensing position, such that a powder is released from apertures in the dispensing plate into a die cavity, laterally moving the dispensing plate back to the pressing position, and pressing the powder in the die cavity to form an article.
Claims21
A powder press, comprising:
- a die comprising a die cavity;
- a lower punch;
- an upper punch;
- a base plate disposed over the die at least in a dispensing position;
- a dispensing plate disposed over the base plate and comprising apertures;
- and
- a fill shoe disposed over the dispensing plate at least in a fill position and configured to dispense a powder into the apertures,
- wherein the base plate and the dispensing plate are configured to independently move laterally between a pressing position in which the base plate and the dispensing plate are disposed below the fill shoe and laterally displaced from the die cavity, and the dispensing position in which the base plate and the dispensing plate are disposed over the die cavity.
