Descriptions:
We are manufacturers and suppliers of all types of Tungsten Carbide Forming Dies Casting Mould.
We produce tungsten carbide die inserts blanks for use in hot and
cold forging nib tooling and casting mould applications. Inserts
are made to order and can be supplied in different tungsten carbide
material grades with up to a 25% cobalt binder to meet our
customer’s specific requirements to produce bolts, screws and
special fixings, in a variety of materials. We produce the die
inserts and blanks in the as-sintered condition with the specific
overall dimensions and special features our customers request ready
for them to produce finished ground tools.
* Usually used in high cobalt and the coarse-grained alloy grades.
* Carbide wear resistance, toughness relationship between the two
are contradictory: to improve the wear resistance will lead to a
decrease in toughness, and improve toughness and wear resistance
inevitably lead reduction. Therefore, the choice of alloy grades,
the need to work in accordance with the object and process
conditions to meet specific requirements.
* If the selected grades in use, prone to crack and damage easily,
a higher toughness grade should be instead; if the selected grade
in use easily wear and damaged, a high hardness grade should be
replaced, wear resistance and better grades.
