Unbreakable Seams, Unmatched Automation: The Intelligent 5-Thread Overlock Powerhouse.

Engineered for heavy-duty durability and smart operation, the ShangGong N550-E-516M redefines safety stitch finishing. This fully automatic overlock combines a robust 5-thread safety stitch—ideal for denim, uniforms, and activewear—with the intelligence of a double stepping motor and direct-drive servo system. It masters the complete production cycle: automatic start, sew, stop, trim, suction, and presser foot lift, ensuring a clean, efficient workflow.

Operators enjoy unparalleled control through an intelligent human-machine dialogue panel on a new floating display, with multiple screen and sewing mode options. The machine protects itself and the product with a sequence logic protection program, a photoelectric fabric sensor for automatic adjustment, and a fully enclosed, oil-free needle bar. Add three-level LED lighting and step-motor controlled trimming for quiet precision, and you have the ultimate automated solution for building the strongest, most professional seams.
