Our Heavy Duty Sewing Machines can automatically select the feeding mode according to the material. The feeding method can also be automatically selected. If the fabric is thick, the mode will be automatically adjusted. You can also manually select intermittent or continuous feeding. Whether you are sewing hard leather or soft canvas, it can adapt perfectly to ensure that every material can be sewn neatly.
The spindle horsepower of Heavy Duty Sewing Machines was specially enhanced during its production at the Sanyou Factory to provide the needle with stronger piercing force, ensuring smooth and stable sewing even when sewing multiple layers of thick materials, without the worries of needle breakage and jamming.
It can be equipped with a new electronic thread tension regulator, allowing for fine-tuning between each stitch and even automatically adjusting thread tension when the sewing direction changes. This means perfect stitch consistency is maintained regardless of variations in fabric thickness.
This presser foot is adjustable. You can adjust the height of the presser foot's lowest point (i.e., the bottom dead center) according to the fabric thickness. It offers an ultra-flexible adjustment range: the standard height is 2 to 4.5 mm, but it can be adjusted up to 10 mm. Don't underestimate this adjustment feature; it effectively prevents annoying problems such as skipped stitches and thread breakage that often occur when sewing thick fabrics. At the same time, it applies appropriate pressure based on the fabric thickness, preventing damage or marks and protecting your valuable materials.
Two sets of templates can be operated alternately, and placed while sewing, which can increase work efficiency by up to 50%.
This sewing machine is also equipped with bright LED lighting. The adjustable brightness LED light makes it easier for the eyes to observe and reduces the visual fatigue of the operator.
