Polycrystalline diamond dies

Mikrotek manufactures polycrystalline diamond dies in the range of 0.025mm – 30.000mm. The dies are strictly manufactured as per customer ordered specifications.

These dies are widely used to make stainless steel, medical wires, low and high-carbon steel, welding wire, copper & aluminum conductors, magnets, EDM tungsten, molybdenum, coated wires, alloy wires and more. The company offers  customized profiles for both wet and dry drawing applications.

The polycrystalline diamond blanks are sourced from well-known manufacturers, mainly M/s Sandvik Hyperion (formerly Diamond Innovations/GE), M/s Sumitomo, and other reputed manufacturers. ‘Compax’, the brand produced by Sandvik Hyperion, is very popular and widely used in the wire and cable industry.
Polycrystalline diamond blanks are available in two types: self-supported and tungsten ring-supported. They also come in different grain sizes of 1, 3, 5, 10, 25, and 50 microns.

These blanks are manufactured in a high-temperature and pressure process. Cobalt is used as a binder between synthetic diamond particles. These are called metal-filled blanks and will withstand temperatures up to 650°C. The cobalt is leached out for high temperatures and special applications so that the blanks can withstand temperatures up to 1200°C. These are called thermally-stable blanks.

Experts at MIKROTEK understand customer’s needs and recommend appropriate (or right) selection of polycrystalline diamond blanks depending on requirements such as wire surface, drawing speed, die life, and more.

Advantages:
- Retention of roundness for a long time.
- Less downtime of the drawing machine.
- Suitable for both wet and dry drawing.
- Suitable for cold and hot drawing.
