When sourcing a tufting machine, the most critical technical parameters are the gauge (distance between needles), stitch rate, and pile height range. For wholesale production, ensure the machine supports common gauges like 3/8", 5/8", or 3/16". Look for machines equipped with servo motor control systems for precise needle movement and high-speed longitudinal cutting devices. Additionally, verify the working width (typically 2m to 5m) to ensure it meets your specific production scale requirements.
