When evaluating a cording embroidery machine, you must prioritize the number of heads and needles (e.g., 12 or 15 needles) to ensure production efficiency. Look for a maximum speed of at least 1000-1200 RPM for industrial output. The embroidery area (e.g., 400x600mm or larger) is critical for accommodating various garment sizes. Additionally, ensure the machine features a high-precision servo motor for stable movement and a Dahao or similar high-end computer control system for complex pattern processing.
