Singer heavy duty sewing machine versatility

The SINGER Heavy Duty 4423 Sewing machine is very versatile. We love that it can sew many different types of fabric. There have been reports of this machine sewing upholstery vinyl, although we have yet to test it. However, we have successfully sewed patches onto a jacket. We were amazed at how well we sewed the rip in a pair of corduroy pants we had to lay around.

Other materials we have tested include hemming denim jeans, sewing cotton dresses for toddlers, and sewing a silk pillow. It has been reported that with this Singer sewing machine, heavy duty tasks like sewing through several pieces of denim at once isn’t a problem. We have yet to test this machine on heavy duty sewing, so we can not confirm it yet, but we are hopeful that it will be strong enough to do so.

When you are sewing with the SINGER machine, a tip I can offer is to be certain that you pick a needle and stitches that go with the thickness of your material. After all, you would not pick a thin needle for super thick or heavy duty material, as the needle will most likely break. It is always a good idea to have extra heavy duty needles on hand as well.

Part of the reason this Singer heavy duty sewing machine is so versatile is that it comes with so many options for stitches. There are twenty-three different stitches to choose from. A great number if you are just starting, not too many stitches to overwhelm you, but still enough options for stitches to offer flexibility. The choices that you have for stitches on this machine include the following:

  • 12 decorative stitches
  • 6 basic stitches
  • 1 buttonhole stitch
  • 4 stretch stitches

With a turn of the stitch length dial, we found you can easily adjust the stitches. The stitch width dial has settings from zero to six, and the stitch length dial has four settings that range from 0.5 to 4mm. When you adjust the length, we have found that you can create different effects for stitches.

This Singer heavy-duty sewing machine is also very fast, providing an impressive number of stitches per minute, good enough even for professional sewers. We have found that you can easily do 1,100 stitches per minute if you are a professional sewer. Those not so experienced can use a slower stitch per minute setting.

Singer 4423 sewing machine modern features

One of the biggest things we first noticed about the SINGER Heavy Duty 4423 Sewing Machine was all the modern features. This goes without saying; we like the devices we purchase to be beefed up in order to get our money’s worth. And so far, we feel like, in the feature department, they completed this task beautifully. Here are some of the modern features you will be sure to notice:

  • Automatic needle threader (No aggravation or straining of the eyes)
  • A top drop-in bobbin (Simple to insert/remove, can tell if the thread is getting low as the cover is transparent)
  • Stainless steel bedplate (ensures any and all material will glide right through the machine)
  • 3 needle positions (For stitching specialty)
  • A foot control pedal (Adjustable to regulate how fast or slow you sew)
  • Snap-on presser feet (Enables you to adjust the presser foot instantly)
  • Adjustable presser foot pressure control (Line up the pressure with the material)
  • Extra-high presser foot lifter (Better clearance when working with heavier materials)
  • Onboard storage (Easy entrance to pieces stashed in the detachable sewing container)
  • Free arm (Effortless entrance to cuffs, hems, collars and other unreachable spots)
  • Automatic reverse (Simple way to reinforce the stitches)
  • Adjustable stitch length and width (A very important feature for a sewing machine to have)
  • High-speed stitches per minute (Professional standard)
  • Super powerful motor (At 105W, this motor is sure to stitch through tough materials like denim and upholstery. It is even possible for this machine to sew through several layers at once)

singer | heavy duty 4423 sewing machine – Foot Control Pedal

If you have never used a foot control pedal on a sewing machine, it will take some time to get used to it. But this is to be expected. You can easily practice with a scrap piece of material to learn what the best speed is for you on the foot pedal. Many users, as well as us, have found that practice in this area will make perfect.

We have found that if you place your entire foot on the pedal it is easier to run. Just placing the tip of your toes on the pedal may cause your foot to slip, which may mess your stitches up.

We have found that the foot control pedal is flexible to use. We like to raise the foot to manage thicker pieces of material. We have also found that if you are just starting to sew, you can leave the foot pedal where it is set at, as it comes pre-set. This is one less thing to do when setting up the machine.

Now, if you desire, you can adjust the thread at this point. This will make sure you have a high-quality stitch on your fabric. You only have to worry about the upper thread as the lower thread tension will be set by the manufacturer.

With the SINGER Heavy Duty 4423 machine, you have four feet of choices. These include:

  • All-purpose foot – used for the majority of your sewing projects.
  • Buttonhole foot – used for adding buttonholes, slots for ribbon, and more.
  • Zipper foot – used for adding zippers, piping, cording, and more.
  • Button sewing foot – used for adding buttons.

There are also nine other feet that you can purchase: hemmer, satin stitch, overcasting, blind hem, cording, straight stitch/quilting, gathering, even feed, and darning/embroidery. With these feet choices, we have found that a wide variety of options have opened up many creative possibilities. We love how easy it is to change the feet. Simply snap off and then back on.

Singer 4423 sewing machines portability

One of the greatest things about the Singer 4423 sewing machine is how portable it is. If you love to sew as much as we do, then you know that having a sewing machine that does not weigh as much as a 100-pound sack of potatoes means a lot! This SINGER 4423 is very portable. At less than 15 pounds, you can easily move it out of one room into another to sew. Or if you do alterations as a side job, you can go to someone’s home if they are not able to travel to you.

We also appreciated the dust cover that comes with the Singer 4423. Keeping the unit clean when it is not in use means that it will be further protected so when we do need it, the unit is in good condition and ready to go.

Easy to Use 4423 sewing machine

We appreciate things that are easy to use. This is one reason we are in love with this SINGER 4423. It is so simple to use, especially with the automatic needle threader and transparent drop-in bobbin cover, but even if you are a novice, you can still refer to the instructions. And if that does not help you, we have found that the smartphone app is even better at getting you through any frustrating parts. You can even find tutorials on YouTube for the Singer 4423 that can offer some pretty great advice on how to sew. All you have to do is take the time to look for them.

Durable singer 4423 heavy duty sewing machine

The SINGER 4423 sewing machine is marketed as being a heavy-duty machine. Now, many of us have purchased things before that were labeled one thing, such as “ice cold”, “super-powerful”, or “heavy-duty” and those products did not live up to that description, to say the least. However, the SINGER 4423 hit it on the head with this one. This sewing machine really is heavy-duty and durable.

The Singer 4423 sewing machine is manufactured with an internal metal frame with a bedplate of stainless steel. There are rigid supports, which allow the sewing machine to operate in perfect alignment.  SINGER states that the motor of the Singer 4423 machine is also 60% stronger than standard Singer sewing machines. We have not been able to find data to back this up, but this could be why sewing heavier material with the Singer 4423 is easier.

One thing we always look for in sewing machines we review is stability while working. We appreciate that while sitting at your table when sewing, the heavy metal frame and components such as the needle threader help to keep the Singer 4423 sewing machine stable. You do not have to worry about the 4423 falling off the table, nor will you have to worry about the material you are working with being fed through the sewing machine at an uncontrolled speed.
