Double-Row Progressive Die for Washing Machine Motor

Designed to replace traditional single-row progressive dies in high-volume home appliance manufacturing lines, this dual-row die integrates 12-20 stamping stations in a compact, rigid structure, enabling simultaneous production of Double-Row Progressive Die for Washing Machine Motor —doubling production efficiency while maintaining household appliance-grade dimensional tolerance (±0.005mm) critical for motor low-noise operation and energy efficiency.

Built on Deaote's 15+ years of expertise in precision mould manufacturing for the home appliance industry, our Double-Row Progressive Die for Washing Machine Motor features a wear-resistant SKD11/DC53 steel core with TiN coating (hardness ≥62 HRC), ensuring a service life of 800,000+ stamping strokes (2.3x 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 top-loading, front-loading, and portable washing machine motors (0.5-2.0HP).

Manufactured under ISO 9001:2015 and IATF 16949 quality standards, the double-row progressive die is fully compatible with high-speed automated stamping lines (60-120 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 washing machine brands (LG, Samsung, Haier, Whirlpool), it seamlessly integrates into global home appliance manufacturing systems, reducing production cost per unit by 30% 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 motor core components per stroke, doubling output compared to single-row progressive dies. The optimized material strip nesting layout also reduces silicon steel waste by 15% (from 20% to 5%), lowering raw material costs—the largest cost component in washing machine motor core production—significantly.

2. Appliance-Grade Precision for Low-Noise & Energy-Saving Performance

5-axis CNC machining with ±0.001mm positioning accuracy and in-die laser gauging systems ensure component dimensional tolerance of ±0.005mm—critical for stator/rotor air gap uniformity (≤0.01mm) and motor noise reduction (≤55dB) and energy efficiency (IEC 60034 compliance). Consistent precision eliminates post-stamping grinding processes, improving production yield to 99.5%.

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

Core die components made of SKD11 (cold work steel) and DC53 (high-strength steel) with TiN coating (hardness ≥62 HRC) deliver 800,000+ stamping strokes—2.3x longer than standard dies (350,000 strokes). Sealed grease reservoirs and self-lubricating guide bushings extend maintenance intervals to 200,000 strokes (vs. 50,000 for conventional dies).

4. High-Speed & Fully Automated Compatibility

Optimized die structure with reinforced stress distribution supports high-speed stamping (60-120 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 0.1%.

5. Silicon Steel Optimization for Motor Energy Efficiency

Specialized punch edge design minimizes silicon steel (35W250/50W400) material stress and edge burrs, preserving the magnetic properties of the steel and improving motor energy efficiency by 5-7%. Compatible with both grain-oriented (GO) and non-grain-oriented (NGO) silicon steel, meeting global home appliance energy efficiency standards (EU Ecodesign, US ENERGY STAR).

6. Modular Customization for Diverse Washing Machine Requirements

Full customization of stamping stations (8-24), material compatibility (0.25-0.5mm silicon steel), surface finish (Ra ≤0.6μm), and dimensional tolerance (±0.003-0.008mm). Optional features include in-die notching, stacking lamination, and laser marking for component traceability—meeting global washing machine OEM requirements.
