Why Choose Us

Company Strengths

Backed by over 32 years of profound R&D, WANYINGHENHUI operates as an industry-leading manufacturer specializing in precision thread forming tools. Our production facility features high-precision CNC thread grinding machinery and a strict internal Quality Control System (QCS), making us the premier partner for Tier-1 industrial fastener suppliers globally.

Ground-Thread Accuracy

Unlike standard tools, every single circular thread rolling die we produce undergoes precision grinding after heat treatment. This completely eliminates thermal deformation, guaranteeing near-zero variance in lead angle and pitch.

Advanced Metallurgy & Smart Hardness Balancing

Utilizing top-grade Cr12MoV and HSS steels, our advanced vacuum heat treatment (certified via ISO9001) gives each circular thread rolling die a mirror-like finish and consistent hardness profiles from core to surface.

Machine-Optimized Consultation

We don’t just supply tools; we match our dies perfectly to your rolling machinery parameters (such as Tsugami, Daishin, Pee-Wee, etc.), ensuring seamless installation and instant uptime.

FAQ

Frequently Asked Questions About Circular Thread Rolling Die

Q1 How do you maintain pitch consistency across ultra-long rods using a thrufeed circular thread rolling die?

Cumulative pitch error is controlled by the lead angle precision of the die. Our CNC thread grinders maintain the helix and lead angle tolerances within microns, ensuring that even on a 6-meter threaded rod, the pitch remains perfectly uniform.

Q2 What is the minimum ordering quantity (MOQ) for wholesale circular thread rolling die sets?

Our flexible MOQ starts from just 2 SETS, helping you avoid heavy inventory burdens during new machine testing or low-volume customization runs.

Q3 Can we order customized circular thread rolling die sets for specific rolling machines like Tsugami or Izui?

Absolutely. We provide complete OEM/ODM customization based on your specific machine spindle diameter, keyway dimensions, and maximum outer diameter limits.

Q4 What are your shipping and delivery lead times for international circular thread rolling die orders?

Standard sizing orders are delivered within 20–25 days. Complex, customized multi-start or specialized coated circular thread rolling die batches are fully processed and shipped within 35–40 days under heavy-duty seaworthy protective packaging.
