SDS.H Series Heated Cylindrical Pellet Die Sets — 13, 25, 50 & 76 mm
Across International’s SDS.H Series heated dry pressing die sets combine hardened steel tooling with a heating system and programmable digital temperature controller for powder pressing applications requiring controlled heat and pressure.
Available in 13, 25, 50 and 76 mm pellet diameters, the series supports heating up to 250°C, with model-specific maximum pressing loads ranging from 20 to 300 tons. Each set includes a heated sleeve, a Pt100 temperature sensor and a WK-1 digital temperature controller.
The hardened steel tooling features a stated Rockwell hardness of HRC 62 and dimensional tolerance of 0.01–0.02 mm (10–20 μm). A thermal isolation plate is supplied with each model to help limit heat transfer to the supporting press components.

Operation & Maintenance
Always wear protective goggles and appropriate protective equipment during operation.
Never exceed the maximum pressing load, temperature or sample loading height specified for the selected model.
Allow the tooling to cool and disconnect electrical power before cleaning.
Clean the tooling thoroughly with absolute ethanol, keeping liquid away from electrical components, and dry it before storage.
Store the tooling in a dry box with silica gel to help prevent surface corrosion.
