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 (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.

Carbide dies normally required by our customers are of the following types :-
(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.
