Tungsten Carbide Dies
Pressed and sintered tungsten carbide dies for cold heading and cold forming, made to customer drawings in YG20C, YG22C, YG25C grades for wear and impact resistance.
Tungsten Carbide Dies Catalogue
Problems This Family Solves
- Steel dies wear out quickly in high-volume cold heading of bolts and fasteners
- Die failure causes inconsistent part dimensions and rejects during forming
- Standard die sizes do not match custom fastener geometries or non-standard thread sizes
- High cobalt grades are used without understanding the trade-off between toughness and wear resistance
- Long lead times delay production ramp-up when a new die is needed
Who Buys These Parts
- Cold heading machine operators producing bolts, screws and fasteners
- Tooling shops developing custom dies for new fastener designs
- Manufacturers of automotive and construction fasteners requiring long die life
- Machinery builders integrating wear-resistant dies into forming presses
- Maintenance teams replacing dies that fail prematurely under repeated impact
Why These Parts Hold Up
- Pressed on imported equipment and sintered in over-pressure furnace for consistent density and closed porosity
- Grades selected based on application: YG20C for wear resistance, YG22C for high impact, YG25C for stainless steel forming
- Standard die blanks available in multiple sizes with defined d, D, L ranges for common fasteners
- Custom die blanks made to drawing including BC, BF, and internal hex types for special applications
- Every order tested for physical properties, shape and tolerance before shipping; inspection photos sent for confirmation
Typical Applications
- Cold heading dies for making standard bolts from carbon steel or stainless steel
- Die blanks for forming internal hex sockets in fasteners using BF type geometry
- BC type sink dies for forming recessed heads in screws and bolts
- High-impact dies for forming nuts and threaded components under heavy load
- Custom die blanks for non-standard fastener sizes not covered by standard tooling
Industries That Use Tungsten Carbide Dies
Pressed Sintered and Ground In House
Weighing In of Ingredients
Tungsten carbide powder and cobalt binder weighed to the grade formula.
Milling
Powders wet milled so the binder is evenly distributed through the mix.
Spray Drying
The slurry is spray dried into free-flowing granules that press consistently.
Testing
Granulate checked before it is committed to a press run.
Forming
Blanks pressed on imported presses from the mould for that part.
Sintering
Sintered at around 1450 degrees C in an over-pressure furnace to close porosity.
Machining
Ground and finished to the dimensions on the drawing.
Quality Control
Physical properties, shape and tolerance checked, then inspection photographs sent before delivery.
Tungsten Carbide Dies FAQ
Can you make dies to my own drawing?
Yes. OEM and ODM to customer drawings is standard. We accept drawings for standard blanks and custom shapes including BC, BF, and internal hex types.
How long is the lead time?
Stock items ship 3-5 days after payment is received. Customised items are quoted with a stated delivery time.
Which grade should I choose for a bolt heading die?
For general wear resistance, use YG20C. For high impact applications like nut forming, use YG22C. For stainless steel or hard materials, use YG25C.
Can I test a sample before ordering in bulk?
Yes. Samples are available for pre-testing. Send the drawing and service conditions and a sample can be quoted.
How are parts checked before shipping?
Physical properties, shape and tolerance are inspected before shipping, and detailed inspection photographs of the order are sent for confirmation before delivery.
Are you a manufacturer or a trading company?
A manufacturer in Zhuzhou, Hunan Province, China, producing tungsten carbide parts for over 15 years.
