Tungsten Carbide Dies for Powder Compaction
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 (envils) with mirror finished surface produce pellets (discs) with excellent surface finish. Most commonly used sizes are :- 10 mm, 13 mm, 20 mm & 25 mm.
Carbide dies normally required by our customers are of the following types :-
(1) Complete Carbide Dies - all parts of Tungsten Carbide
(2) Die Body with inner lining of carbide & outer casing of
hardened steel. Punches &
Pusher rod are made of hardened steel.
(3) Die body of hardened steel. Punches & pusher rod
are made of carbide.
The dies can be subjected to a maximum load of 25 Tons,
desired pellet diameter.
Tungsten Carbide being brittle in nature, is not guaranteed against breakage.
Hence, it should be handled with utmost care.
