Tungsten Carbide Dies for Powder Compaction 

 


For certain specific applications, dies made from tungsten carbide are preferred over those made from die 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, 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.
