Core Advantages

1. Full Compound Design for Integrated One-Step Stamping

Integrated blanking, punching, notching, and lamination processes in a single stamping cycle eliminate 3-4 traditional processing steps for 500mm Outer Diameter Full Compound Die for NEV Stator and Rotor. This one-step solution reduces production lead time by 40% and core assembly error by 80%, ensuring perfect alignment of stator/rotor laminations (parallelism ≤0.008mm) critical for NEV motor efficiency.

2. 500mm OD High-Rigidity Frame for Zero Deformation

Reinforced die frame made of S50C high-strength steel with stress-relief heat treatment (HV ≥220) and precision guide pillars (runout ≤0.002mm) ensures zero deformation even under 350 Ton stamping force. The symmetric structural design minimizes vibration during high-speed stamping, maintaining dimensional accuracy of ±0.005mm for 500mm large-size cores—critical for NEV motor air gap uniformity (≤0.01mm).

3. Premium Coated Tool Steel for Extended Service Life

Core punch components made of SKH-51 (high-speed steel) and ASP23 (powder metallurgy steel) with TiAlN coating (hardness ≥68 HRC) deliver 780,000+ stamping strokes—2.1x longer than standard large-size dies (370,000 strokes). The TiAlN coating provides high-temperature resistance (up to 500°C) and wear resistance, extending maintenance intervals to 180,000 strokes (vs. 70,000 for conventional large dies).

4. NEV Motor-Grade Precision for Power Density

7-axis CNC machining with ±0.0008mm positioning accuracy and in-die laser gauging systems ensure component dimensional tolerance of ±0.005mm—critical for NEV motor power density (≥3.5kW/kg) and energy conversion efficiency (≥96%). Consistent precision eliminates post-stamping machining, improving production yield to 99.7% for 500mm large-size cores.

5. Silicon Steel Optimization for NEV Energy Efficiency

Specialized punch edge design with micro-radius (R0.015mm) minimizes silicon steel (27Q130/35W250) material stress and edge burrs (≤0.008mm), preserving the magnetic properties of the steel and improving NEV motor energy efficiency by 5-7%. Compatible with high-grade non-grain-oriented (NGO) silicon steel, meeting global NEV motor efficiency standards (EU WLTP, US EPA).

6. Modular Customization for NEV Motor Diversity

Full customization of stamping processes (blanking/punching/notching/lamination), material compatibility (0.35-0.5mm silicon steel), surface finish (Ra ≤0.4μm), and dimensional tolerance (±0.004-0.007mm). Optional features include in-die stacking, insulation coating compatibility, and laser marking for traceability—meeting global NEV OEM requirements for traction motor core production.
