Strip Cupping Press

Advanced Cupping System

Servo-Driven Double-Action Cupping

The OTM-5200 features a double-action servo system with a 50-ton inner ram for forming cups and a 75-ton outer ram for blanking strip material. The 2-inch outer stroke and 4-inch inner stroke are precisely controlled via the Weintek HMI, allowing adjustments for tool temperature, stroke timing, and head positioning with multi-program memory. Unlike traditional flywheel presses, which require mechanical overhauls for timing changes, the servo system enables on-the-fly adjustments, reducing setup time and enhancing productivity. The 4-post die sets process up to 8 cups per stroke, delivering high throughput for calibers like 9mm and 5.56×45, while maintaining precision for larger calibers like 338 Lapua.

• Process: Outer ram blanks strip, inner ram forms cups in a single cycle
• Outcome: High precision, consistent cup dimensions, minimal material waste
• Applications: Brass casing cups, copper jacket cups for pistol and rifle ammunition

Yaskawa Servo Drives

The OTM-5200 integrates Yaskawa servo drives, renowned for nearly 50 years of reliability in high-tonnage applications. These drives, paired with Yaskawa PLCs (with an optional Allen Bradley upgrade), provide real-time feedback, remote access, and precise motion control for the inner and outer rams. The system supports customizable tooling designs, with quick adjustments via the HMI, ensuring versatility across calibers. Yaskawa’s durability ensures the press can withstand hundreds of millions of cycles, minimizing maintenance and supporting continuous, high-volume production.

• Features: Precision motion control, customizable programs, durable servo motors
• Benefit: Enhances flexibility and reduces maintenance in demanding environments
• Reliability: Ensures consistent performance for high-speed cupping operations

Automated Brass Processing

The OTM-5200’s automated feed system includes an uncoiler with expandable arbor and a straightener, ensuring accurate alignment of brass or copper strip (e.g., ~4.75″ width for 9mm tooling) with the press tooling. The system handles various strip sizes, supporting a wide range of products. The closed coolant system, controlled from the main panel, uses industry-standard pumps for continuous duty, maintaining optimal tooling conditions. The station isolation system allows operators to identify and rectify out-of-spec parts without halting production, ensuring seamless operation with only one experienced operator (a second recommended for coil changes).

• Mechanism: Uncoiler, straightener, and coolant system for efficient material handling
• Outcome: Reduces operator intervention and maintains production quality
• Applications: High-volume production of brass and copper cups

Efficient Scrap Management

The OTM-5200 offers flexible scrap management with a standard re-coiler for collecting scrap or an optional scrap chopper to minimize footprint and simplify processing. The scrap chopper saves floor space by cutting scrap into manageable pieces, while the re-coiler supports continuous operation. Both systems are enclosed in safety fencing with magnetic gates, ensuring operator safety and compliance with industry standards. This efficient scrap handling reduces material waste and enhances cost-effectiveness in high-volume manufacturing.

• Options: Re-coiler or scrap chopper for scrap processing
• Benefit: Minimizes footprint and reduces waste handling costs
• Safety: Enclosed systems with magnetic gates protect operators
