* Long life of the thread rolling die
Henghui is specialized in the making of screw thread rolling dies, made of best raw materials available in the market. These screw thread rolling dies are designed professionally by our engineers per customers’ specifications or work pieces. Each staff tries try his best to have screw thread rolling dies with high accuracy, high strength and high stability by high skills and strict quality control system.Therefore the screw thread rolling dies life is longer than dies produced by other companies based on the same materials and the same price or even lower price.
Henghui manufacture thread rolling dies taking the needs of our customers very much into account. The range of thread rolling dies covers most of threading machines on the market. Likewise, we cover all kinds of screw threads.
We also manufacture custom thread rolling dies to customer specifications. You can see examples of different designs and shapes in the product details page.
Furthermore, we advise our customers in choosing the type of thread rolling die that best suits their needs. You can send your technical inquiries to us, and we will be in touch within 24 hours to offer you the best solution.
Advantages
1. Superior Wear Resistance Long Service Life
Technical Highlights:
Material Excellence: Manufactured from high-grade alloy steel (e.g., HSS, powder metallurgy steel) or cemented carbide, achieving
surface hardness up to HRC 58-65.
Surface Treatment: Nitriding, TiN/TiCN coatings, or cryogenic treatment enhance wear resistance by 30-50%.
Performance Benefits:
Withstand high-pressure rolling of hardened materials (e.g., stainless steel, titanium alloys).
Reduce tool replacement frequency, lowering production downtime.
Typical Applications: High-volume fastener production (screws, bolts), automotive components.
2. Precision Thread Profiles & Consistency
Technical Highlights:
Advanced Machining: CNC grinding or wire EDM ensures thread pitch accuracy within ±0.005 mm and profile tolerance <0.01 mm.
Stress-Free Process: Cold rolling technology improves thread strength by 20-40% compared to cutting methods.
Performance Benefits:
Eliminate burrs and microfractures, ensuring smooth thread surfaces.
Maintain uniform thread dimensions across millions of cycles.
Typical Applications: Aerospace fasteners, medical implants, precision machinery parts.
3. High EfficiencyAdaptability
Technical Highlights:
Optimized Design: Multi-rib or segmented dies enable rapid thread forming (e.g., 200-500 pieces/minute).
Versatility: Compatible with diverse materials (aluminum, carbon steel, superalloys) and thread types (metric, UNC, UNF).
Performance Benefits:
Reduce energy consumption by 15-30% vs. traditional cutting.
Support custom profiles (e.g., trapezoidal, ACME threads) for specialized industries.
Typical Applications: Hydraulic fittings, electrical connectors, construction hardware.
