This is a compact, high-quality, and work efficient heavy-duty sewing machine with a single machine head that holds one needle that is operated at working speeds of 860SPM.

It has a convertible sewing bed that is set at default as a raised-type sewing bed, but the removal of the extension table converts it into a free-arm bed for sewing cylindrical clothes or apparel.

Also, this model comes hard-coded with 18 sewing stitches and a 1-step button-hole stitch. Among the special stitches that can be made are the zigzag, overcast, tricot, overedge, outline stretch, and triple stretch stitches.

It can also be used on heavy-weight fabrics like denim, coating, overcoat, canvas, leather, vinyl, tweed, and upholstery fabric using size 16-18 needles. As expected, the recommended threads to be used in Singer 4432 are cotton, silk, polyester, and synthetic threads.

This heavy-duty singer 4432 machine is shipped in a single package that weighs about 17pounds, and is 15.2inches long, 6.3inches wide, and 12inches tall.

Therefore, the model 4432 shipping package is lighter and smaller than the model 4452 shipping package, and this confirms that the 4432 model comes without the bonus package found in the 4452 model.

Likewise, because the price of the model 4432 and model 4452 are almost the same, it makes model 4452 the better choice of the 2 models.

Inside the model 4432 package is the fully-assembled Singer 4432 unit, a needle set, quilting guide, 15 transparent INSPIRA- or SINGER-branded bobbins, seam ripper, auxiliary spool pin, lint brush, felt, general purpose foot, spool caps, screwdriver, zipper foot, buttonhole foot, and button-sewing foot, as well as a soft dust cover.

Also, in the package is a trilingual instruction manual that contains instruction sets in English, Spanish, and French. The 4432 sewing unit is made of a heavy-duty metal frame and its color scheme is gray.

The front face of the upright arm of this sewing machine features the stitch length dial and the pattern selector dial, while the side panel features the handwheel, machine power port, switch for power and light, and a balance adjustment slot for the buttonhole stitch.

On the other hand, the front panel of the horizontal arm features the reverse sewing lever, while the top panel features the thread tension dial, needle position dial, bobbin stopper, presser-foot pressure adjustment, and the stitch width dial.

Singer 4432 comes with a LED sewing light for illuminating the work area, and this machine is backed by a 12-month limited warranty.
