JUKI LH-4578CFF DIGITAL TWIN NEEDLE FOUNDATION WEIGHT SEMI-DRY HEAD INDUSTRIAL SEWING MACHINE

Juki LH-4578CFF is a foundation-weight, 2-needle, full digital lockstitch sewing machine designed for ultimate stitch precision, consistency, and operator efficiency. Featuring independent active tension control, active presser foot adjustment, a 1.8x capacity large hook, and IoT connectivity, it represents the next generation of intelligent sewing technology for the garment industry.

With its semi-dry head and minute-quantity hook lubrication, the LH-4578CFF minimises oil staining while maintaining high-speed performance and exceptional seam quality – even at up to 3,000 stitches per minute. The machine’s multilayered portion detection ensures smooth transitions over thick seams, preventing stitch gathering and improving overall finish quality.
