| Compact Computer Multi-Needle 12 | 12 needles | Approximately 200–300 mm throat space; suitable for blocks, borders, and small panels | Up to approximately 1,000–1,200 stitches per minute, depending on material and design | Approx. 6–10 standard quilt blocks per hour after setup; actual output varies with stitch density and hoop changes | Built-in pattern library, USB design import, basic scaling, rotation, pattern combination, and stitch-density adjustment | Needle-break detection Upper-thread sensor Motor overload stop | Clean hook and bobbin area after each project; oil according to the service schedule; replace needles regularly; inspect thread path weekly | Home studios, sample production, small quilting businesses, and users with limited workspace |
| Production Computer Multi-Needle 15 | 15 needles | Approximately 300–450 mm throat space; supports larger blocks and continuous border work | Up to approximately 1,000–1,300 stitches per minute | Approx. 8–14 standard quilt blocks per hour with prepared designs and stable fabric handling | Color touchscreen, multi-area pattern editing, automatic tie-off, thread-color mapping, USB/network transfer, and design preview | Thread-break monitoring Presser-foot sensor Emergency stop Restart-position memory | Daily lint removal; regular hook cleaning and lubrication; check needle timing, thread tension, and frame alignment during scheduled service | Quilt shops, custom orders, and mixed-size production where flexibility is more important than maximum throughput |
| High-Output Computer Multi-Needle 20 | 20 needles | Approximately 450–600 mm throat space; designed for larger quilt panels and repeated motifs | Up to approximately 1,000–1,400 stitches per minute | Approx. 10–18 standard quilt blocks per hour, depending on design complexity, hooping, and operator workflow | Advanced nesting and repeat functions, automatic sequencing, stitch-preview simulation, editable lettering, network or USB design transfer, and production memory | Upper and lower thread sensors Needle-position control Over-temperature protection Door and cover interlock | Clean moving parts at the end of each shift; lubricate specified points; inspect belts, hook assembly, needles, and tension system; perform periodic calibration | Professional quilting services, repeat-pattern work, larger custom orders, and small-batch production |
| Industrial Computer Multi-Needle 24 | 24 needles | Approximately 600–750 mm throat space; intended for large panels, long borders, and continuous production | Up to approximately 1,000–1,500 stitches per minute, subject to fabric weight and design density | Approx. 12–22 standard quilt blocks per hour in a prepared production workflow; large all-over designs require additional handling time | Production-oriented software with repeat templates, multi-zone editing, automatic color sequencing, job storage, stitch estimation, and batch setup tools | Multi-point thread monitoring Emergency-stop circuit Servo overload protection Automatic needle-stop position | Daily cleaning and inspection; scheduled lubrication; frequent needle and bobbin checks; professional timing, drive-system, and electrical inspection at planned intervals | Contract quilting, high-volume workshops, educational production rooms, and businesses requiring reduced color changes |
| Large-Format Computer Multi-Needle 30 | 30 needles | Approximately 750–1,000 mm throat space; accommodates wide quilt sections and fewer repositioning steps | Up to approximately 900–1,400 stitches per minute | Approx. 14–24 standard quilt blocks per hour when designs, fabric preparation, and loading are standardized | Large-format pattern preview, automatic repeat and alignment, design mirroring, multi-step job scheduling, removable media support, and detailed production reporting | Thread and needle monitoring Access-panel interlock Overload and overheat protection Controlled emergency stop | Requires disciplined cleaning, lubrication, tension checks, frame inspection, and scheduled technician servicing; adequate ventilation and stable power are recommended | Large-scale quilting operations where wide working space, fewer fabric repositionings, and high repeatability justify the higher maintenance demand |
