Ammo Linking
Discover the OTM-7100LM, an advanced automatic linking machine for 7.62x51mm NATO cartridges with optional conversions for other rifle types. Featuring dual feeders, preset ratios for ball/tracer, and up to 60 PPM, ensure precision for belt-fed weapons. Contact Ammo Rx for scalable solutions!
Details
The OTM-7100LM, engineered by On The Mark Ammunition Solutions and delivered by Ammo Rx, is an advanced automatic ammunition linking machine designed for precision assembly of disintegrating belts for belt-fed weapons. Optimized for linking 7.62x51mm NATO cartridges, with optional conversions for other rifle ammunition types, this robust system features dual live ammo feed systems for ball and tracer rounds and a link vibratory feeder for seamless integration at preset ratios (e.g., 4:1).
Adjustable production rates reach up to 60 parts per minute, with lot counting functionality that pauses operations for manual belt separation via a plunger or optional automatic upgrades. Live ammunition is fed through zig-zag tubes into a rotating turret, where it’s horizontally pushed into the linking belt using a safe pneumatic system (with mechanical cam upgrades available), contacting only the head stamp to avoid primer risks.
This compact yet powerful machine requires 220V power and 100 PSI air, delivering high-speed linking with belt break capabilities, minimal downtime, and maximum productivity—ideal for ammunition manufacturing facilities seeking precision, scalability, and compliance in military and commercial applications.
- Purpose: Automates linking of rifle cartridges into disintegrating belts for sustained fire in belt-fed systems
- Key Benefit: Enables preset ball/tracer ratios, reduces manual handling, and ensures safe, efficient assembly
- Production Capacity: Up to 60 parts per minute, scalable for high-volume operations with lot control
Additional Information
More Details
Advanced Linking System Dual Feeding Technology The OTM-7100LM is a dedicated linking center, optimized for assembling rifle ammunition into belts. It features dual live ammo feeders for ball and tracer cartridges, combined with a vibratory link feeder, allowing preset ratios for specialized belts. Ammunition is channeled through zig-zag feed tubes into the system, ensuring consistent orientation and flow. This design supports reliable integration of components, minimizing jams and enabling high-speed production for demanding environments.
- Technology: Dual ammo feeders with vibratory link system for ratio-controlled assembly
- Outcome: Streamlines belt creation, enhancing firepower reliability in belt-fed weapons
- Applications: 7.62x51mm NATO belts, military sustainment, customizable for other rifle calibers
HMI/PLC Control System Powered by an intuitive HMI/PLC interface with the OTM software suite, the OTM-7100LM provides user-friendly operation and real-time monitoring. Operators can adjust speeds, set lot counts, and receive overload-protected error communications for low air/part levels or other alerts. This system supports seamless batch management, minimizes intervention, and ensures precision in 24/7 production settings.
- Features: Adjustable rates, lot counting with pause, real-time diagnostics
- Benefit: Reduces setup times and boosts efficiency with minimal training
- Reliability: Designed for durability with proven performance in industrial workflows
Modular Conversions And Caliber Flexibility The OTM-7100LM offers optional conversions for quick caliber changes, allowing operators to adapt to different rifle specifications with minimal downtime. This flexibility supports transitions between NATO standards and other variants, ensuring precise linking across ammunition lines. Upgrades like mechanical cams and automatic separation enhance versatility for diverse production needs.
- System: Optional conversions and upgrades for rapid reconfiguration
- Benefit: Increases adaptability and efficiency in multi-caliber operations
- Applications: Primarily 7.62x51mm NATO, with tailoring for other rifle rounds
Linking Mechanism The OTM-7100LM’s linking system ensures safe, precise assembly with a rotating turret that horizontally pushes cartridges into the belt via pneumatic actuation (cam upgrade available). Contact is limited to the head stamp area, avoiding primers for enhanced safety. Belt break capabilities allow pausing for separation, supporting continuous operation and integration with downstream processes in high-volume setups.
- Mechanism: Turret-based push with pneumatic/cam actuation for secure linking
- Outcome: Eliminates risks and supports scalable belt production
- Applications: Ideal for military belt-fed systems, reloading, and tactical assembly
