Used HJM Precision Ignition Cartridge Non-Destructive Inspection Machine | PLC Controlled | 3-Axis Robot | Built 2019
Overview
Description
Used HJM Precision, Inc. Ignition Cartridge Non-destructive Inspection Machine. The machine has been designed and manufactured for the purpose of inspecting Ignition Cartridges for leaks. It is controlled by a PLC with an HMI for the operator to move the machine in manual mode for homing, clearing product, cleaning, etc., and to operate the machine in automatic mode. The cartridges are loaded into the machine in an input tray. The cartridges are then placed in test chambers by means of a robot. The chambers are moved to the test position. Covers lower to the top of the test chambers and nozzles extend to the test chambers near the bottom. Three axis robot system consisting of three slides and a gripper. The robot moves in X, Y , and Z directions with X being the length of the machine, Y across the machine, and Z vertical. Four test chamber blocks on the dial plate. Each of the test chamber blocks has four chambers in them. Gilmont flow meters and Hoke needle valves are used to calibrate the machine. New in 2019.

๐ญ Manufacturer
HJM Precision, Inc.
A specialized manufacturer of automated and high-accuracy inspection systems for defense, aerospace, and industrial components. Known for customized solutions and robotic NDI (non-destructive inspection) platforms.
๐ Description
This HJM Precision Ignition Cartridge Non-Destructive Inspection Machine was designed and built in 2019 specifically to inspect ignition cartridges for leaks in a fully automated or manual-controlled environment. The system features a three-axis robotic loading mechanism, precision test chambers, and operator-friendly PLC + HMI interface for control and diagnostics.
The machine uses a tray-based loading system, where cartridges are robotically moved into test chamber blocks. Each block contains four chambers, and the entire testing process is automated, repeatable, and non-invasive, ensuring consistent leak testing without damaging sensitive munitions.
