Title:
Development of 20mm Plastic/Aluminum Cartridge Case
Corporate Author:
AAI CORP COCKEYSVILLE MD
Report Date:
1974-03-01
Abstract:
The final design for the 20mm plastic aluminum cartridge is arrived at by studying and eliminating, if possible, the case cracking problems encountered during temperature extreme firings, improving case resistance to rough handling, and establishing molding process parameters for high volume production. The basic case consists of a plastic body joined mechanically to an aluminum base forming a composite assembly. The existing plastic aluminum case design is used as a basis, and modifications are made to it as judged necessary. Each modification is followed by test firing to verify and record any changes in performance and case integrity.
