We help you identify the right natural diamond die based on your wire drawing machine type, wire material, final diameter, and surface finish requirements. Send us your current die specifications or machine model and we’ll match the right tooling to your operation.
We supply natural diamond dies for wire drawing machinery across the wire and cable industry, offering one of the most precise and durable tooling solutions available for fine wire and ultra-fine wire production. Our portfolio covers a broad range of die aperture sizes, approach angles, and bearing lengths to match the exact requirements of your drawing line, whether you’re working with copper, aluminum, precious metals, or specialty alloys.
Natural diamond dies are the benchmark for applications where surface quality and dimensional accuracy are non-negotiable. The single-crystal structure of natural diamond delivers unmatched hardness, exceptional thermal conductivity, and a naturally low friction coefficient — all of which translate into reduced wire breakage, longer die life, and consistent output quality on high-speed multi-block drawing machines and single-block drawing machines alike.
We work with operations running equipment from leading manufacturers such as Niehoff, Samp, Koch, MFL, among others. Our natural diamond wire drawing dies are compatible with these machine platforms and can be specified to meet your exact wire drawing die geometry — including reduction angle, bearing length, back relief angle, and die case dimensions.
Beyond standard copper wire drawing and aluminum wire drawing applications, natural diamond dies are widely used in the production of magnet wire, enamel wire, medical wire, fine gauge wire for electronics and telecommunications, as well as precious metal wire such as gold, silver, and platinum for the jewelry and semiconductor industries. Their performance in tungsten wire drawing and other refractory metal applications also makes them the preferred choice for demanding specialty wire production.
We support customers globally with fast sourcing, technical consultation, and worldwide shipping of wire drawing tooling. Whether you need a single replacement die or a full set for a new drawing line, we can assist with selection, specification review, and delivery to minimize downtime on your production floor.
