Hardened Steel Cutting Dies
Hardened steel cutting dies are designed for the precise and repeatable preparation of test specimens used in standardized materials testing. Manufactured from high-strength, heat-treated tool steel, these dies provide exceptional durability and edge retention, allowing them to consistently cut clean, dimensionally accurate specimens from tougher materials such as rigid plastics, reinforced elastomers, composites, and semi-rigid sheets.
Engineered for use with laboratory presses, hardened steel dies are capable of cutting material thicknesses typically ranging from 0 to 10 mm, depending on material hardness and press capacity. The rigid construction minimizes deformation during cutting, ensuring that specimen geometry remains within tight tolerances—critical for generating reliable mechanical property data such as tensile strength, elongation, and modulus.
These dies are commonly used in preparation for standards such as ASTM D638, ASTM D412, and ASTM D624, where precise specimen dimensions directly influence calculated results. Clean cut edges reduce the risk of stress concentrations or premature failure during testing, improving data consistency across samples.
Available in a wide range of geometries—including bone-shaped (dog-bone), rectangular strip, trouser tear, and custom profiles—hardened steel cutting dies support a broad spectrum of ASTM, ISO, and DIN test methods. Compared to ribbon steel dies, hardened steel options are better suited for higher volume use, thicker specimens, and harder materials due to their superior wear resistance and structural integrity.
Universal Test Machine Co. offers a comprehensive selection of hardened steel cutting dies, along with compatible arbor presses and accessories, providing a complete solution for ASTM-compliant specimen preparation across plastics, rubber, and advanced materials testing applications.
