Double-Row Progressive Die for AC Compressor Core

The core magnetic components of rotary, scroll, and reciprocating AC compressors. Double-Row Progressive Die for AC Compressor Core is designed to replace traditional single-row progressive dies in high-volume HVAC manufacturing lines, this dual-row die integrates 16-26 stamping stations in a compact, rigid structure, enabling simultaneous production of two sets of compressor core components per stroke—doubling production efficiency while maintaining compressor-grade dimensional tolerance (±0.004mm) critical for magnetic circuit integrity and compressor energy efficiency.

Built on Deaote's 15+ years of expertise in precision mould manufacturing for the HVAC compressor industry, our Double-Row Progressive Die for AC Compressor Core features a wear-resistant DC53/SKD11 steel core with TiCN coating (hardness ≥63 HRC), ensuring a service life of 850,000+ stamping strokes (2.4x 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 (1-5HP) and commercial (5-12HP) AC compressors.

Manufactured under ISO 9001:2015 and IATF 16949 quality standards, the Double-Row Progressive Die for AC Compressor Core is fully compatible with high-speed automated stamping lines (70-130 strokes per minute) and features integrated in-die vision inspection systems for real-time quality control (defect detection rate ≥99.9%). Compatible with all major AC compressor brands (Panasonic, Hitachi, Daikin, LG, Carrier), it seamlessly integrates into global HVAC component manufacturing systems, reducing production cost per unit by 32% compared to single-row die solutions.

Core Advantages

1. Double-Row Design for 100% Production Efficiency Gain

Integrated two parallel stamping rows enable simultaneous production of two identical or mixed compressor core components per stroke, doubling output compared to single-row progressive dies. The optimized material strip nesting layout also reduces silicon steel waste by 17% (from 23% to 6%), lowering raw material costs—the largest cost component in compressor core production—significantly.

2. Compressor-Grade Precision for Magnetic Circuit Integrity

5-axis CNC machining with ±0.0008mm positioning accuracy and in-die laser gauging systems ensure component dimensional tolerance of ±0.004mm—critical for stator/rotor air gap uniformity (≤0.009mm) and compressor energy efficiency (COP ≥3.1, SEER ≥21). Consistent precision eliminates post-stamping grinding processes, improving production yield to 99.6%.

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

Double-Row Progressive Die for AC Compressor Core is made of DC53 (cold work steel) and SKD11 (high-carbon steel) with TiCN coating (hardness ≥63 HRC) deliver 850,000+ stamping strokes—2.4x longer than standard dies (350,000 strokes). Sealed grease reservoirs and self-lubricating guide bushings extend maintenance intervals to 210,000 strokes (vs. 60,000 for conventional dies).

4. High-Speed & Fully Automated Compatibility

Optimized die structure with reinforced stress distribution supports high-speed stamping (70-130 strokes per minute) and full integration with automated material feeding, stacking, and packaging systems. The in-die vision inspection system detects burrs (≤0.009mm), dimensional deviations, and surface defects in real time, eliminating manual quality control and reducing scrap rate to 0.09%.

5. Silicon Steel Optimization for Compressor Energy Efficiency

Specialized punch edge design minimizes silicon steel (35W300/50W470) material stress and edge burrs, preserving the magnetic properties of the steel and improving compressor energy efficiency by 6-8%. Compatible with both grain-oriented (GO) and non-grain-oriented (NGO) silicon steel, meeting global HVAC energy efficiency standards (EU Ecodesign, US ENERGY STAR).

6. Modular Customization for Diverse Compressor Requirements

Full customization of stamping stations (12-30), material compatibility (0.30-0.55mm silicon steel), surface finish (Ra ≤0.5μm), and dimensional tolerance (±0.002-0.007mm). Optional features include in-die notching, stacking lamination, and laser marking for component traceability—meeting global AC compressor OEM requirements.
