Jack E4S-5-03/333 5 Thread Overlock Industrial Sewing Machine

Professional Industrial Overlock Machine for High-Volume Production

The Jack E4S-5-03/333 is a professional-grade 5-thread overlock industrial sewing machine engineered for high-volume production environments like garment factories, export-oriented tailoring units, and large-scale boutique operations in Bangladesh. This machine combines a high-speed sewing capability with the strength to handle multiple layers of medium to heavy-weight fabrics commonly used in denim, workwear, and upholstery, providing a durable safety stitch that overlooks and seams in one efficient operation.

Key Features & Benefits

• Professional 5-Thread Safety Stitch: Creates a robust stitch that simultaneously seams, trims, and overcasts the fabric edge, producing a clean, professional, and durable finish that prevents fraying. It is the industry standard for constructing strong seams in shirts, trousers, jackets, and activewear.
• High-Speed Industrial Performance: Capable of up to 6500 stitches per minute (SPM) to boost productivity. The integrated direct-drive servo motor provides instant start/stop control, high torque at low speeds, and improved energy efficiency.
• Built for Durability and Stability: The heavy-duty cast-iron body absorbs vibration and maintains alignment during continuous operation. The automatic oil bath lubrication system minimizes wear and extends service life.
• User-Oriented Adjustability: Features an easy-to-adjust differential feed to prevent stretching or puckering of knitted fabrics, along with an adjustable stitch length lever for versatility across materials.

Ideal Use-Cases & Installation Guidance

This machine is perfectly suited for businesses involved in the mass production of woven garments where strong, finished seams are critical. It is a fundamental machine for any serious garment manufacturing or large tailoring setup in Bangladesh.

Installation should be performed by a qualified technician. The machine requires a stable industrial table, a proper 220V power connection, and routine maintenance as per the manual. Always use recommended industrial-grade needles and threads for optimal performance. Local Jack-authorized dealers typically provide installation support and after-sales service.
