Core Forming Press

Advanced Core Forming System

Servo-Driven Core Swaging The OTM-5175C leverages servo-driven technology to execute a high-precision swaging process, transforming lead wire into seamless, cylindrical cores with exact weight uniformity, diameter control, and density for optimal ballistic integrity. The 75-ton servo press ram, adjustable from a 2-inch to 8-inch stroke, allows dynamic control over force, stroke length, and swaging speed via the Weintek HMI, enabling lube adjustments and multi-program memory for storing parameters. This precision ensures high-accuracy output for calibers like .50 BMG, while the part present die protection system prevents errors, enhancing reliability in high-volume production.

• Process: High-pressure swaging for lead cores with core seating and bleed holes for excess material ejection
• Outcome: Uniform density, precise tolerances (±0.001″ diameter), minimal defects like core bleed inconsistencies
• Applications: FMJ, soft-point, and hollow-point cores for pistol, rifle, and large-caliber bullets (9mm to .50 BMG)

Servo-Controlled Transfer System The OTM-5175C’s servo-controlled transfer system, featuring a servo transfer bar, servo strippers, and servo ejectors, ensures seamless movement of lead cores through multiple swaging stations. This system supports complex forming sequences, maintaining precise alignment for core shaping and weight adjustment. The interchangeable tooling packs allow rapid caliber changes, making the press versatile for standalone or integrated bullet production lines. Multi-feed systems can be integrated for high-throughput swaging, enhancing flexibility for specialty projectile cores.

• Mechanism: Servo-driven transfer bar, strippers, and ejectors for multi-station swaging
• Benefit: Enhances precision and efficiency in core production, reducing cycle times and waste
• Applications: Lead cores for FMJ projectiles, soft-point bullets, multi-piece assemblies

Core Swaging for Ammunition Core swaging is a cornerstone of ammunition manufacturing, compressing lead wire under immense pressure in dies to form dense cores with high structural integrity and consistent grain structure. The OTM-5175C excels in producing swaged cores for applications requiring superior ballistic performance and dimensional accuracy, such as military and hunting rounds. The servo-driven system optimizes core density, diameter, and weight uniformity, reducing material waste and ensuring compatibility with subsequent processes like jacket assembly or ogive forming. Industry insights highlight swaging’s role in achieving reliable projectile expansion and penetration, making the OTM-5175C a critical tool for precision bullet crafting.

• Advantages: High-density construction, uniform weight distribution, reduced porosity for better accuracy
• Applications: Cores for 9mm to .50 BMG, including military-grade FMJ and soft-point hunting bullets
• Servo Benefits: Programmable stroke and force improve swaging quality, repeatability, and energy efficiency

Robust Press Design The OTM-5175C features a weldment frame engineered for durability, with a machined bolster plate and press ram honed for flatness and accuracy. The 75-ton press capacity and heavy-duty linear ram guides ensure stability during high-force swaging operations, while the servo indexer enhances cycle efficiency. A coolant tank with sealed drain area, automatic oiler, and scrap chute for excess lead or bleed ejects maintain a clean, efficient workspace. The full machine enclosure, magnetic door interlocks, and 3/8″ polycarbonate guarding provide operator safety, making the press a reliable, low-maintenance solution.

• Components: 75-ton servo ram, coolant system, carbide tooling, servo indexer
• Benefit: Ensures long-term reliability and high-throughput core production
• Environment: Sealed coolant system and scrap chute minimize mess and maintenance
