Polycrystalline diamond is manufactured by forming a mass of diamond crystals and then applying a combination of heat and pressure. Through this process, the mass becomes a single unit with the diamond particles inter-grown to each other. The final product is extremely wear resistant, maintains tight hole tolerances, and provides good surface finish.
Carbide dies have been used in the wire industry for many years. They are used in various drawing applications where diamond dies are not economical or where hole tolerance is not as critical.They are used extensively in the steel industry as well as the nonferrous industry in applications such as bunching or stranding large diameter cables. These dies are available in a large range of nib and hole sizes.
