Precision Feeding + Quality Inspections
The OTM-20PM enhances efficiency with its OTM-160A left-hand case feeder and OTM-6PF vibratory primer feeder, featuring bowl level sensors and high/low primer slide sensors to monitor status and alert operators when primers run low. Standard dual powder and bullet OAL laser inspections, auto-eject for bad parts, and optional pre-primed or cracked case detection minimize defects and streamline workflows.
- Mechanism: OTM-160A case feeder, OTM-6PF primer feeder with sensors for precision ammo processing
- Benefit: Reduced handling, faster changeovers, and cleaner workflows with minimal operator intervention
- Applications: Primer insertion for pistol, rifle, and large-caliber casings from 380 ACP to 338 Lapua
Robust, Production-Ready Design
Engineered for durability, the OTM-20PM features Nickel coatings for corrosion resistance and surface hardness, full guarding with 1/4″ polycarbonate windows, and magnetic door interlocks for operator safety. With anti-static systems, IP65 minimum and Class 1 Division 2 electrical ratings, this USA-made machine ensures reliable, low-maintenance operation in demanding environments.
- Components: Continuous motion dial, guided primer seat, OTM-160A case feeder, anti-static systems for durable priming
- Benefit: High uptime, reduced maintenance, and robust performance in ammo manufacturing settings
- Environment: Protected surfaces, sealed electronics, and safe operator access for long-term reliability
Product Feeding
Every OTM-20PM includes the OTM-160A left-hand case feeder with bowl level sensors, a polycarbonate lid with dome lights for status, and quick-swap tooling for seamless caliber changeovers. The OTM-6PF vibratory primer feeder, capable of 300 parts per minute with tooling changes, uses high and low primer slide sensors to alert operators when the bowl needs refilling, minimizing downtime and ensuring efficient priming.
