Used HJM Precision Ignition Cartridge Non-Destructive Inspection Machine | PLC Controlled | 3-Axis Robot | Built 2019

🏭 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.

📝 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.
