Method for manufacturing magnetron molybdenum end cap through die forming

The invention discloses a method for manufacturing a magnetron molybdenum end cap through die forming. The method comprises the steps of (1) designing a die, wherein the dimension of a sintering ingot is compared with the dimension of a pressing ingot, the dimension shrinkage ratio is calculated, and the corresponding die is manufactured as per the shrinkage ratio on the basis of the dimension and the forming method of the magnetron molybdenum end cap; (2) conducting die forming, wherein the same granulation powder as that used in Step (1) is filled into the designed die to be produced into a molybdenum end cap pressing ingot through die forming; (3) subjecting the obtained molybdenum end cap pressing ingot to vacuum degreasing presintering to obtain a molybdenum end cap degreasing presintering ingot; (4) sintering the obtained molybdenum end cap degreasing presintering ingot to obtain a molybdenum end cap sintering ingot; and (5) conducting polishing and hydrogen calcination on the obtained molybdenum end ca
