Mechatronic Design, Easy Installation

Driven by a servomotor, it features low vibration, low noise, high performance, and excellent sewing quality.

Automatic Lifter & Thread Trimmer for Energy Savings and Efficiency

Thanks to automatic presser foot lift and automatic thread trimming functions, work efficiency is increased and labor costs are reduced.
Dot-Matrix Control Panel, Easy Operation Thanks to pattern and parameter display functions, there is no need to consult the user manual, which simplifies operation. You can freely set the number of soft-start stitches, dynamically monitor and adjust the machine speed, making operation more convenient.
Wide Application Range, Flawless Stitches The JK-781GK machine is equipped with a special presser foot for knitting, a small needle plate, and a feed plate. For highly elastic fabrics, it can also press and sew beautiful stitches. This machine is more suitable for knitted materials with a low thread breakage rate.
Short Thread Tails, No Need for Manual Trimming Equipped with a short thread-trimming presser foot, needle plate, and feed plate for thin woven fabrics, changing the thickness of the small needle plate keeps the thread tail within 3 mm. Thus, factories can reduce thread-trimming costs, lower enterprise expenses, and increase profitability.
Bobbin Thread Detection If the bobbin thread supply is insufficient, the machine will promptly pause operation after completing the current buttonhole.
Automatic Counting Function This function allows you to automatically record the number of buttonholes for easy counting and quick inspection.
