Tungsten Carbide Thread Rolling Dies

Introduction

Thread rolling is a cold forming process that creates threads by displacing material rather than cutting it. Tungsten carbide thread rolling dies are essential for high-volume thread production.

Advantages of Thread Rolling

Rolled threads are stronger, smoother, and more fatigue-resistant than cut threads. The cold work strengthens the material grain structure. Carbide dies ensure consistent thread form over millions of parts.

Carbide Thread Rolls

Carbide thread rolls offer exceptional wear resistance and dimensional stability. They maintain precise thread profiles through millions of rolling cycles, producing consistent fastener threads.

Applications

Carbide thread rolling dies are used for bolts, screws, studs, and threaded rods. They serve the automotive, construction, and fastener industries where high-volume thread production is required.

Grade Selection

Tough carbide grades are preferred for thread rolling because the process involves high pressure and impact. Medium to coarse grain grades with higher cobalt content resist chipping under rolling forces.

Custom Thread Forms

Beyond standard metric and imperial threads, custom thread forms can be produced on carbide rolls. Special profiles, knurling, and combined rolling operations are available.

Conclusion

Tungsten carbide thread rolling dies deliver consistent, high-quality threads at high production volumes. They are essential for competitive fastener manufacturing.
