Details
The OTM-BCA Conveyorized Belt Annealing Machine, delivered by Ammo Rx—your premier supplier of cutting-edge ammunition manufacturing solutions—is a through-feed system that restores ductility to work-hardened brass cups via uniform heating on a continuous mesh belt. Essential for relieving stresses post-cup forming to prevent cracks during subsequent drawing, this machine uses multi-zone electric resistance or gas-fired heating chambers to ensure consistent temperature profiles, often with optional inert gas atmospheres like nitrogen to minimize oxidation. Featuring integrated cooling sections and anti-static designs, the OTM-BCA advances annealing for calibers from .300 AAC to .338 Lapua, offering energy-efficient, high-throughput solutions for ammunition production where traditional batch furnaces fall short in speed and uniformity.
- Purpose: Uniform annealing of brass cups to restore ductility and prevent failures in ammunition manufacturing
- Key Benefit: Continuous belt technology for efficient, oxidation-resistant processing and enhanced brass durability
- Production Capacity: Up to 200 parts/min (caliber-dependent), with 90% efficiency

Advanced Annealing System
Continuous Belt Annealing
The OTM-BCA utilizes a metal mesh belt conveyor to transport brass cups through multi-zone heated chambers, providing seamless, uniform annealing that outperforms batch methods by enabling high-volume through-feed with controlled temperature gradients—critical for stress relief without over-softening or distortion. This process, common in metal processing, incorporates optional inert atmospheres to prevent surface oxidation, making it ideal for primary annealing post-cup forming in ammunition lines where consistency directly impacts downstream reliability.
- Process: Through-feed belt conveyance for targeted heating of brass cups in annealing
- Outcome: Restored ductility, extended material life, and minimized cracks for superior ammo performance
- Control: Weintek HMI and Allen Bradley PLC for precise zone temperature monitoring and adjustments
Integrated Post-Process Cooling
Ensure optimal results with the OTM-BCA’s built-in cooling sections, which rapidly quench annealed cups to lock in ductility while preventing thermal distortion—reducing reject rates and enhancing workflow efficiency. This feature integrates seamlessly with the belt system, using air or gas quenches to confirm uniform treatment, ideal for high-precision ammunition manufacturing.
- Mechanism: Automated cooling and verification post-heating for reliable brass processing
- Benefit: Lower defects, faster throughput, and reduced labor in ammo cup annealing
- Applications: Cooling of annealed cups across rifle calibers for defect-free outputs
Robust, Production-Ready Design
Engineered for industrial demands, the OTM-BCA features acid-resistant mesh belts, sealed heating chambers, and safety interlocks, ensuring longevity and operator protection during continuous operation. With a modular footprint and durable construction, this USA-made annealing furnace supports low-maintenance, high-uptime performance in ammunition facilities, safeguarding against environmental factors while maintaining precise heat treatment.
- Components: Mesh belt conveyor, multi-zone heaters, optional inert gas systems for secure brass annealing
- Benefit: Enhanced safety, reduced downtime, and robust reliability in high-volume production
- Environment: IP65-rated electronics and enclosed design for clean, efficient ammo manufacturing
Product Feeding
Every OTM-BCA includes integrated hoppers and vibratory feeders for seamless loading of brass cups onto the conveyor belt, supporting high-speed input with anti-static features for caliber-specific adjustments. This intuitive system minimizes interruptions, enhances efficiency in through-feed annealing, and ensures smooth transitions without compromising precision or quality in ammunition brass heat treatment.
