METHOD OF MAKING A PROJECTILE BY METAL INJECTION MOLDING |
| 摘要 |
The present invention provides a method of making a metal ammunition projectile by metal injection molding comprising the steps of: providing a projectile mold to form a nose extending essentially symmetrically to a shoulder; and an essentially cylindrical bearing surface extending from the shoulder to a base; providing a metal injection molding feedstock comprising a powdered metal and a first binding agent and a second binding agent; injection molding the metal injection molding feedstock into the projectile mold to form a first projectile having a first size; debinding the first projectile to remove the first binding agent; and sintering the first projectile to remove the second binding agent and form a projectile having a second size. |

1. A method of making a metal ammunition projectile by metal injection molding comprising the steps of:
providing a projectile mold to form a nose extending essentially symmetrically to a shoulder; and an essentially cylindrical bearing surface extending from the shoulder to a base; providing a metal injection molding feedstock comprising a powdered metal and at least a first binding agent and a second binding agent; injection molding the metal injection molding feedstock into the projectile mold to form a first projectile having a first size; debinding the first projectile to remove the first binding agent; and sintering the first projectile to remove the second binding agent and form a projectile having a second size. |
