Production Procedure of Tungsten Carbide Products
This is the route every part on this site follows. Each step limits what the next step can achieve which is why material problems cannot be fixed at the grinding stage.
1. WC PowderTungsten carbide powder from a region with abundant mineral resource
2. Ball MillingPowder and binder milled to a uniform mixture
3. Spray DryingSlurry dried into free flowing granulate
4. Mixed PowderPrepared powder checked and released
5. PressingBlanks pressed to shape with machining stock
6. Sinter-HIPSintering with isostatic pressure to close porosity
7. MachiningGrinding EDM and lapping to the approved drawing
8. Finished ProductInspected packed and prepared for export

FAQ
Questions Buyers Ask Before Ordering
What tungsten carbide products do you manufacture?
We produce carbide rods strips blades dies inserts pins buttons rings tubes gears saw tips oil field carbide parts and API V11 series ball and seat valve pairs. Every category on this site is produced in our own plant.
Where is your factory located?
Our plant is in Changsha the capital of Hunan Province in China where mineral resource is abundant. The registered office is at Room 1108, Tian You Building, 10 Ba Yi Road, Furong District, Changsha, Hunan Province, China.
Which countries do you export to?
Our tungsten carbide products are sold to USA, Germany, UK, Italy, Sweden, Chile, India, Vietnam, Turkey and South Africa.
Can you produce parts to my own drawing?
Yes. Custom made carbide parts to drawing are a normal part of our production. Send the drawing or photos of a worn sample with measured dimensions on WhatsApp or by email and our engineers will respond.
How do I get a quotation?
There is no enquiry form on this site. Send your drawing quantity and application on WhatsApp to +86 187 7492 5813 or email [email protected] and the message reaches an engineer directly.
What is Sinter-HIP and why does it matter?
Sinter-HIP applies isostatic gas pressure during the sintering cycle so residual porosity inside the carbide is closed. Porosity is where cracks start which is why it matters for dies buttons and large wear parts.
Next Step
Send Us the Part You Cannot Keep in Service
A drawing a sketch or a photo of the worn part with measured dimensions is enough to start. Your message goes to an engineer not to a form.
Send a drawing or a sample photo on WhatsApp or by email. Files are reviewed by our production engineers, not by a form.
