Across International Cylindrical Dies for Pellet Presses
Comprehensive Range of Standard Cylindrical Pellet Dies
Across International cylindrical die sets provide traditional solid-sleeve pressing solutions for creating round cylinder-shaped pellets across an extensive range of diameters from 6mm to 100mm, with maximum pressure capabilities ranging from 4 tons to 250 tons. This comprehensive eleven-model collection—SDS6, SDS8, SDS10, SDS13, SDS15, SDS20, SDS25, SDS30, SDS50, SDS75, and SDS100—offers hardened steel dry pressing die sets ready for immediate use in spectroscopic sample preparation, material testing, pharmaceutical applications, and research laboratories requiring standard cylindrical pellet geometry. Each die set is precision-engineered to accommodate samples up to 1/3 of sleeve height, a critical limitation that ensures proper pellet formation, prevents die damage, and maintains safe operating conditions during high-pressure pressing operations. The cylindrical design provides the most common and widely-used pellet geometry for XRF analysis, FTIR spectroscopy, and other analytical techniques where standardized round pellets are the established protocol.
Premium Hardened Steel Construction with Industrial-Grade Precision
All cylindrical die sets achieve Rockwell Hardness Rc 62 through premium hardened steel construction, with smaller models (6mm through 25mm) utilizing W18Cr4V hardened carbon tool steel for core dies and push rods, transitioning to combinations of W18Cr4V and Cr12 hardened carbon mold steel for mid-range models (15mm through 30mm), and employing Cr12 hardened carbon mold steel exclusively for larger high-pressure models (50mm, 75mm, 100mm). This material selection optimizes durability and performance characteristics for each capacity range while maintaining exceptional pressing die tolerances of 0.01-0.02mm (10-20 microns) across all configurations. Each complete die set includes highly polished core dies (one to three depending on model size), steel sleeve, support plate or base, push rod (with detachable handle on larger models), and pellet ejector—providing everything needed for immediate pellet production. The SDS8 model includes an aluminum carrying case for enhanced portability and protection. Unlike split-sleeve or vacuum dies, these traditional cylindrical designs offer simplicity, reliability, and cost-effectiveness for laboratories performing routine pellet pressing where standard sample release mechanisms are sufficient and specialized features like vacuum capability or easy-retrieve technology are not required.

Safety and Maintenance
Critical Safety Requirements:
- Always wear protective goggles and safety gear during pressing operations.
- NEVER fill die more than 1/3 of sleeve height - critical for proper pellet formation and safety.
- Never exceed specified maximum pressure for your die size.
- Ensure proper alignment of all components before applying pressure.
Maximum Pressure Limits:
- SDS6: 4 tons | SDS8: 8 tons | SDS10: 10 tons | SDS13: 15 tons.
- SDS15: 20 tons | SDS20: 25 tons | SDS25: 30 tons | SDS30: 40 tons.
- SDS50: 100 tons | SDS75: 150 tons | SDS100: 250 tons.
Maintenance Instructions:
- Clean die sets thoroughly with absolute ethyl alcohol after each use.
- Store in dry box with silica gel to prevent surface corrosion.
- Inspect highly polished surfaces regularly for scratches or wear.
- Ensure all components move freely without binding.
- Check that push rods and ejectors function smoothly.
Important Notice: Across International is not responsible for any damage caused by misuse, overfilling beyond 1/3 sleeve height, or exceeding maximum pressure specifications.
