Application of carbide cold heading die
The tcarbide cold heading die are used for cold punching and heading of srews and nuts, with high
wear resistance and high toughness. Also, it is the ideal material
in making non-ferrous metal, ferrous metal and other alloy.
Decription of carbide cold heading die
carbide cold heading die area is one of the main applications of tungsten carbide material. carbide cold heading die usually can be divided into punching die and bushing die , used in
cold heading, warm heading and hot heading technology situation.
carbide cold heading die is a process technology which make the work piece transformation
and the shape close to the finished product to the utmost extent in
few processes. It is the milestone of modern mechining and
automobile industry.

Production of carbide cold heading die
1, Soon after the order is confirmed, carbide cold heading die products will start to prepare the RTP powder as per customer’s
requirement with our wet-grinding machine
2, Before mass production, we need to do a trial pressing and
sintering using every mould, and we check the appearances and the
sizes of the samples with micrometer, projectors etc. to ensure
that the requirements of the drawings can be met before batch
production
3, Bulk production ,press the raw materials to shape blanks,and all carbide cold heading die blanks must be passed by semi finished inspection,
4, Then sinter blanks to finish (HIP) and finished products
inspection, we have 10 sets of vacuum sintering furnace and 2 sets
of HIP in the factory ensure the best quality and production
capacity.
5, 1). cleaning/tumbling is to make the carbide cold heading die look more beautiful.
2).The carbide cold heading die can be ground according to customers’ order to a tolerance of
+/-0.05
Packing and delivery of carbide cold heading die
