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.
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.
Tungsten Carbide being brittle in nature, is not
guaranteed against breakage. Hence, it should be handled
with utmost care.
