5. Singer 4432 Heavy Duty Sewing Machine

This is a professional-grade, compactly-designed, and heavy-duty mechanical sewing machine whose sewing head holds one needle that is operated at a maximum working speed of 1100SPM. It has a convertible sewing bed that can be set as a raised-type bed or a free-arm bed.

Likewise, this variable needle position model allows for multiple sewing techniques such as piping insertion, edge stitching, topstitching, and zipper application.

Evidently, this model is quite similar to the Singer 4452 model reviewed above. So why did Singer give the same model 2 different model numbers?

The answer as highlighted earlier in the review is that Singer 4432 is the base model, which when packaged with a bonus bundle becomes model 4452.

As expected, this model 4432 machine does not come with an even feed/walking foot, size 16 heavy-duty needles, a non-stick foot, nor a clearance plate.

Like in Singer 4452, the selection of stitch pattern and stitch length in Singer 4432 is done using the pattern selector dial and stitch length dial respectively. At the top of the 4432 machines protrudes the thread tension dial, stitch width dial, and the three-needle position dial.

This model is similar in terms of operational design to the Singer 4432, but it differs in functional capacity because the 4423 model cannot handle the extreme workloads that model 4432 can handle.

Like Singer 4432, this is a variable needle position model that allows for multiple sewing techniques such as piping insertion, edge stitching, topstitching, and zipper application.

It can also be used for quilting and its sewing bed features an embossed stainless-steel plate. Likewise, its throat space is adequate for holding quilted material.

Relatedly, it allows for pivot sewing, has an automatic needle threader, and provides for top-loading of its transparent, easy-to-thread bobbin into the bobbin case. Also, it comes with a Snap-On presser foot, and supports an extra high lift of this foot, as well as provides for adjustment of foot pressure.

Moreover, it allows for manual thread-tension control. Also, regarding power supply and consumption, it is similar to model 4432. The model 4423 model requires 84-120 watts of power supplied at 120 Volts AC, 60 Hz.

This power runs its high-performance variable-speed motor that operates the needle-bar that inserts the threaded needle into the fabrics. It also comes with foot control for regulating motor speed.

Therefore, when compared to model 4432, model 4423 is less power efficient than model 4432 because it handles less work as compared to model 4432 for the same amount of electrical power.

This proves that additional components in model 4432 give it an edge over model 4423. For instance, unlike Singer 4432 that comes with 6 presser feet, model 4423 comes with 4 presser feet.

Singer 4423 is designed to stitch light-weight and fine fabrics such as lawn, georgette, tricot, cottons, interlocks, voile, silk, crepes, blouse, shirt, muslin, and polyester fabrics using size 7-11 needles.

It is also suitable for sewing medium-weight fabrics like wool, sheeting, knit, kettle-cloth, satin, sailcloth, terrycloth, denim, and jersey using size 11-14 needles. It can also be used on heavy-weight fabrics like denim, coating, overcoat, canvas, vinyl, and tweed using size 16-18 needles.

The recommended threads to be used in this machine are cotton, silk, polyester, and synthetic threads. Unlike Singer 4432, this model is not suited for sewing leather materials.

Singer 4423 was introduced into the market in July 2010. It is shipped in a single package that weighs about 14.5pounds, and is 15.5inches long, 6.25inches wide, and 12inches tall.

Inside the package is the fully-assembled Singer 4423 unit, a needle set, instruction manual, quilting guide, 15 plastic 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.

The sewing unit is made of a heavy-duty metal frame and its color scheme is gray. The front panel of the upright arm of Singer 4423 features a stitch length dial and 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.

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.

Regarding the automatic thread cutter, it is located to the side of the sewing head. There are 2 storage compartments in this model – one in the horizontal arm and the other in the extension table.

Moreover, it comes with a light-emitting diode (LED) for illuminating the work area. It is therefore evident that its construction design is quite similar to the Singer 4432 model. Even so, one cannot upgrade this model using accessories so as to perform leather stitching that model 4432 can do.

This model is backed by a 12-month limited warranty.
