Product Specifications

Technical details and manufacturing context for Primer Assembly and Insertion Module

Definition
A specialized industrial module within the Modular Small Arms Ammunition Production System responsible for the precise assembly of primer components and their subsequent insertion into prepared cartridge cases. This module ensures consistent primer seating depth, orientation, and secure placement critical for reliable ammunition ignition.
Working Principle
The module receives cartridge cases from upstream processes and primer components from feeding systems. It precisely positions the primer cup, adds the anvil and priming compound, then uses controlled mechanical force to insert the assembled primer into the cartridge case pocket. Sensors verify proper assembly and insertion before passing components downstream.
