For certain specific applications, dies made from tungsten carbide are preferred over those made from hardened alloy steel. Tungsten carbide has very high compressive strength & hence can take high pressure. Each Die consists of outer die body, punches (envils), pusher rod & pellet removal ring. Carbide Punches (anvils) with mirror finished surface produce pellets (discs) with excellent surface finish.
Most commonly used sizes are :- 6, 8, 10, 13, 15, 20 & 25 mm.
(1) Die Body with inner lining of carbide & outer casing of hardened alloy steel. Punches & Pusher rod are made of hardened alloy steel or carbide.
(2) Die Body of hardened alloy steel. Punches & pusher rod are made of hardened alloy steel or carbide.
The dies can be subjected to a maximum load of 25 Tons, depending upon desired pellet diameter.
Note :Tungsten Carbide being brittle in nature, is not guaranteed against breakage. Hence, it should be handled with utmost care.
