The SEWKEY Overlock Sewing Machine is a high-performance industrial serger engineered for high-volume garment manufacturing, fabric finishing, and edge trimming. Operating at speeds of up to 7,500 stitches per minute, it simultaneously trims and binds raw fabric edges to deliver clean, durable, and fray-resistant seams. Equipped with a differential feed mechanism, the machine ensures smooth, puckering-free feeding on lightweight materials and prevents stretching on knits and spandex. Available in 3-thread, 4-thread, and 5-thread configurations, it features customizable settings for stitch length, width, and thread tension to accommodate a wide range of textiles from delicate synthetics to medium-heavy fabrics.
