Tungsten Carbide Parts for Mould and Die Making
Moulds and dies operate under high pressure and repetitive motion. Wear on sealing rings leads to leakage, reduced part quality, and unplanned downtime. This page covers the cemented carbide sealing rings made here for mould and die applications and how they are specified.
What Goes Wrong Today
- Sealing rings in moulds wear out quickly under high pressure and repeated cycling
- Leakage from worn rings causes product defects and contamination
- Rings deform or crack under high load, requiring early replacement
- Non-uniform ring dimensions across batches cause fit issues in assembly
- Standard steel rings fail in abrasive or corrosive environments common in die casting
What Buyers In This Sector Need
- Sealing rings that resist wear and deformation under high pressure and repeated use
- Rings made to an existing mould or die drawing for direct replacement
- Flat and step-type rings with precise dimensions and minimal tolerance
- Samples available for testing before bulk production
- Consistent dimensions and material properties across reorders

Mould and Die Making FAQ
Can you make sealing rings from our mould drawing?
Yes. OEM and ODM to customer drawings is standard, including non-standard and specially shaped parts.
What sizes are available for tungsten carbide rings?
Standard sizes range from Ø12mm to 400mm. Custom sizes are made to drawing.
Do you offer samples before bulk production?
Yes. Samples are available for pre-testing before bulk production is released.
How is dimensional consistency maintained across reorders?
Repeat parts are made from the same mould and grade, with physical properties, shape, and tolerance verified against the drawing before each shipment.
What grades are used for sealing rings in moulds and dies?
Grades produced include YL10.2, YG6, YG6X, YG8, YG8X, YG10, YG12, YG15, YG15X, YN6, YN9. The grade is selected based on the application.
What lead time should we plan for custom rings?
Customised items carry a stated delivery time in the quotation. Stock items ship in 3-5 days after payment.
