INJECTION MOULDED SHAPED CHARGE LINER AND METHOD OF FORMING THEREOF (EMBODIMENTS)

摘要

A method of forming a shaped charge liner is proposed, the liner formed by injection moulding, where the liner (10) components include powdered metal (18) and organic binder (20). The liner components are blended then processed within an injection molding device (12) and urged from the molding device (12) into a mold (28) where a liner shape (30) is formed. The liner shape (30) is debinded, both mechanically and chemically. Mechanical debinding involves heating and chemical debinding comprises treating the liner shape (30) with a solution to dissolve and remove the binder (20) components. The process of forming the shaped charge liner (10) does not include sintering. The present process can also use "green products" (30) formed by the injection molding device (12) that are not debinded. A shaped charge case (6) can also be formed using the present method. The added step of sintering can be applied to the process of forming the shaped charge case (6).
