Triple-Row Progressive Die for AC Compressor Stator and Rotor

Triple-Row Progressive Die for AC Compressor Stator and Rotor is designed to replace traditional single/double-row progressive dies in high-volume HVAC manufacturing lines, this triple-row die integrates 18-28 stamping stations in a compact, rigid structure, enabling simultaneous production of three sets of stator/rotor components per stroke—tripling production efficiency while maintaining micron-level dimensional tolerance (±0.003mm) critical for compressor magnetic performance.

Built on Deaote's 15+ years of expertise in precision mould manufacturing for the HVAC industry, our triple-row progressive die features a wear-resistant DC53/ASP23 steel core with CrN coating (hardness ≥65 HRC), ensuring a service life of 1,000,000+ stamping strokes (3x longer than standard dies) and consistent precision over the entire production cycle. The modular design with quick-change punch inserts simplifies maintenance and reduces downtime, making it ideal for 24/7 mass production lines of residential (1-3HP) and commercial (3-10HP) AC compressors.

Manufactured under ISO 9001:2015 and IATF 16949 quality standards, the triple-row progressive die is fully compatible with high-speed automated stamping lines (80-150 strokes per minute) and features integrated in-die vision inspection systems for real-time quality control (defect detection rate ≥99.95%). Compatible with all major AC compressor brands (Panasonic, Hitachi, Daikin, LG), it seamlessly integrates into global HVAC component manufacturing systems, reducing production cost per unit by 40% compared to single-row die solutions.

Core Advantages

1. Triple-Row Design for 200% Production Efficiency Gain

Integrated three parallel stamping rows enable simultaneous production of three identical or mixed stator/rotor components per stroke, tripling output compared to single-row progressive dies. The optimized material strip nesting layout also reduces silicon steel waste by 20% (from 25% to 5%), lowering raw material costs—the largest cost component in stator/rotor production—significantly.

2. Micron-Level Precision for Compressor Magnetic Performance

5-axis CNC machining with ±0.0005mm positioning accuracy and in-die laser gauging systems ensure component dimensional tolerance of ±0.003mm—critical for stator/rotor air gap uniformity (≤0.01mm) and compressor energy efficiency (COP ≥3.2). Consistent precision eliminates post-stamping grinding processes, improving production yield to 99.7%.

3. Ultra-Long Service Life with High-Hardness Materials

Core die components made of DC53 (cold work steel) and ASP23 (powder metallurgy steel) with CrN coating (hardness ≥65 HRC) deliver 1,000,000+ stamping strokes—3x longer than standard dies (300,000 strokes). Sealed grease reservoirs and self-lubricating guide bushings extend maintenance intervals to 250,000 strokes (vs. 50,000 for conventional dies).

4. High-Speed & Fully Automated Compatibility

Optimized die structure with reinforced stress distribution supports high-speed stamping (80-150 strokes per minute) and full integration with automated material feeding, stacking, and packaging systems. The in-die vision inspection system detects burrs (≤0.01mm), dimensional deviations, and surface defects in real time, eliminating manual quality control and reducing scrap rate to 0.05%.

5. Silicon Steel Optimization for Energy Efficiency

Specialized punch edge design minimizes silicon steel (35W250/50W470) material stress and edge burrs, preserving the magnetic properties of the steel and improving compressor energy efficiency by 5-8%. Compatible with both grain-oriented (GO) and non-grain-oriented (NGO) silicon steel, meeting global HVAC energy efficiency standards (SEER ≥20, EER ≥14).

6. Modular Customization for Diverse Compressor Requirements

Full customization of stamping stations (12-32), material compatibility (0.35-0.5mm silicon steel), surface finish (Ra ≤0.4μm), and dimensional tolerance (±0.002-0.008mm). Optional features include in-die notching, stacking lamination, and laser marking for component traceability—meeting global AC compressor OEM requirements.
