JACK A4C Series - Computerized Lockstitch Sewing Machine

The JACK A4C Series NTB (New Thread Balance) is a next-generation computerized lockstitch sewing system designed to redefine efficiency and precision in garment manufacturing. Powered by the Octopus Nine-brain AI chip, the machine intelligently calculates optimal fabric feeding force in real time, ensuring perfect synchronization between thread handling, fabric movement, and stitch formation.

A key innovation of the A4C Series is the 0-degree Thread Path Technology, which minimizes thread resistance and reduces thread tension by up to 30%, resulting in smoother stitching, improved seam quality, and reduced thread wear.

The integration of AI and mechanical precision significantly enhances performance, reducing the thread breakage rate by up to 80% while increasing overall productivity by approximately 5%.

The A4C Series is designed to handle a wide range of materials—from thin fabrics to heavy-duty textiles—through its multiple model configurations. With high sewing speeds of up to 5000 stitches per minute, the machine ensures rapid production without compromising stitch quality.

Its robust construction, combined with intelligent automation, makes it ideal for high-volume manufacturing environments where consistency, speed, and reduced operator dependency are critical.
