Heavy-duty mechanical sewing machines are built with robust materials and components. They often feature a metal frame that provides stability and reduces vibrations during operation, ensuring precise stitches. The heavy-duty presser foot is another key element; it exerts more pressure on the fabric, allowing for smooth feeding of multiple layers and thicker materials without skipping stitches. These machines typically come with a range of stitch options, including straight stitch, zigzag, and specialized stitches like bar tacks, which are frequently needed in heavy sewing projects.
