Tungsten Carbide Lined Dies are manufactured from high-grade tungsten carbide in a hardened tool steel case. They are a high quality alternative where steels have failed to improve die wear.
Tungsten Carbide is one of the hardest and most wear-resistant substances known to man. Made from a special formulation of powders which are pressed and then sintered to bond the powders into a hard and homogenous structure with superior crystalline structure and uniformity.
Die wear can be identified by a prominent 'ringing' in the area of the bore where the tablet is compressed, and normally occurs when abrasive products are being compressed, high pressures are used to form the tablet or the dies are used beyond their expected service life.
Tungsten Carbide Lined Dies are machined to the same fine tolerances and finish as solid steel dies. The tungsten carbide insert is tested under high loads prior to despatch to ensure integrity of bond between the outer case and the liner.
