Special Sewing Machine

The Computer Direct Drive Fancy Stitch Machine, model YJ-3020M/3525M, is a state-of-the-art industrial sewing solution engineered for high-performance stitching in decorative and technical sewing applications. Designed with a focus on speed, precision, and automation, this machine integrates advanced motor control with sophisticated mechanical engineering to meet the growing demands of modern sewing production environments.

Product Features

The YJ-3020M/3525M is equipped with an original computer direct-drive motor, which delivers rapid start and stop responsiveness. This design eliminates transmission losses common in belt-driven systems and contributes to a time-saving performance improvement of approximately 19% compared to traditional models. With faster acceleration and braking, the operator experiences smoother transitions between sewing actions, boosting both efficiency and control.

Capable of high-speed sewing with perfect stitch quality, the machine supports decorative and precision sewing on a wide range of materials. The integrated presser foot control system maintains stable thread tension, both upper and lower, which ensures flawless results regardless of fabric thickness. The system’s minimum resolution of 0.05 mm makes it particularly suitable for fine detail work, making each stitch clean, uniform, and visually refined.

A major feature of the YJ-3020M/3525M is the adjustable big presser foot, designed for consistent pressure distribution. This allows the material to move and rotate smoothly under the needle, especially when stitching curves or decorative motifs. The equilibrium of pressure across all sides of the foot ensures that delicate or textured materials are not distorted, enhancing control and stitch placement.

This machine also incorporates a high degree of programmability, giving operators control over stitch patterns, lengths, speeds, and foot pressure. These settings can be stored and recalled, enabling seamless transitions between different production lines or materials.

Application Scenarios

The YJ-3020M/3525M is particularly effective in the production of decorative seams and technical stitches across industries such as fashion apparel, leather goods, and household textiles. It is frequently used for:

• Jacket and Suit Manufacturing: The precision and speed make it an ideal suit sewing machine, especially for lapels, sleeve heads, and decorative edging.

• Embroidery and Quilting Applications: It complements automated design work by providing fast and clean fancy stitching on pre-quilted or embroidered items.

• Shoes and Accessories: The large presser foot and high-tension thread control make it perfect for adding decorative topstitching or reinforcement to leather shoes, bags, and belts.

• Home Textiles: Suitable for detailed stitching on curtains, cushions, and bedding with decorative or repetitive stitch patterns.
