SINGER | 4423 Heavy Duty Sewing Machine


This is a high-speed sewing machine that comes from a renowned brand. This heavy-duty machine will prove helpful to you in most scenarios, and it is a sewing machine that must be on your wishlist.

What is a heavy-duty machine?

The word heavy-duty often gets thrown around as a way to market a product. It actually means that a machine can sew through tough fabric like leather and denim. The speed of these sewing machines should range between 800 and 1500 stitches per minute. Also, heavy-duty machines are usually mechanical, as computer parts tend to break easily, and these machines are meant to be used daily and for longer periods of time.

But don’t be confused; heavy-duty machines are by no means industrial ones. Industrial sewing machines are used in factories, and heavy-duty ones are meant to be used at home. So you can say that they fall somewhere in the middle between typical home sewing machines and industrial ones.

Do I need a heavy-duty machine?

Heavy-duty sewing machines are designed to be very durable and used every day, and they are definitely an investment meant to last a long time. They are built to handle tougher fabrics and have powerful motors.

They also have a built-in needle and tons more features that will make sewing fun. So if you are looking to get serious about sewing, you might want to get a heavy-duty machine. It is a nice investment, and you will be grateful for your stable and durable machine that does the job perfectly without giving you a headache.

Is Singer 4423 Good?

This type of sewing machine is a good choice for both beginners and someone who has stitched thousands of stitches in their life. It does fall into the heavy-duty category, and it is durable thanks to its heavy frame and powerful motor. Speaking of which, the 4423 has a motor that can stitch 1100 stitches per minute.

Another feature is the automatic needle threader, and there are 24 stitches, twelve decorative stitches, six basic, four stretch stitches, and one buttonhole. You can also change the length of the stitches to 4mm and the width to 6mm. The 4423 does not lack features, so you’ll have everything you need all in one machine. It comes with an all-purpose buttonhole, zipper foot, and button sewing foot.

We already mentioned that the needle threading is done automatically, but you can also choose between three positions, right, left, or center. The bobbin thread system is very easy to keep track of because both the bobbin and the bobbin cover are transparent. The metal frame it’s made from does not allow the machine to shake and move all over the table while you work with it.

The warranty is similar to most sewing machines and lasts 25 years. That seems like a lot, but keep in mind that the 25-year mark only covers the sewing machine head. Warranty from manufacturing failure only lasts 90 days, and motor and wiring components malfunctions are covered for two years.

Is the singer heavy duty 4423 loud?

The machine is pretty quiet, making it perfect for the house. You don’t have to worry about waking up the entire building block while making yourself a dress like with the older sewing machines.

Will a singer heavy duty 4423 sew leather and canvas?

The 4423 is a durable, mechanical sewing machine that can sew leather and canvas, but we would recommend only going up to medium thickness, so as not to stress the machine.

Disadvantages of Singer 4423.

Even though singer heavy duty 4423 is considered an overall good sewing machine, it does have some disadvantages that might bother you. First, the paddle is way more sensitive than beginners can handle, and it may take some time to get used to it. Since it’s considered a beginner-friendly sewing machine, this is worth mentioning.

The buttonhole foot can also be a cause for concern because it’s made to look and feel cheap. The automatic needle threader is a huge plus, as we mentioned, but it will only work properly if the needle is upright. And the last thing that might bother people is the steel metal plate in the sewing space. Not because there is something wrong with it, but because it tends to get smudgy and dirty very fast.

What do I get in the box?

If you decide to purchase the Singer heavy duty 4423 sewing machine, you will get a few treats in the box. Of course, the actual machine, along with the sewing foot pedal, power cord, and four presser feet. Also, you get a dust bag to cover your machine with and an instruction manual. If you are not a fan of old-fashion manuals, you can always download the Singer App and get your information there.

On the other hand, YouTube is a great informational platform where you can see other people using the machine while they give you tips and tricks on how to use it yourself. Last but probably most interesting, you get an accessory case that includes needles, a combo seam ripper, a lint brush, a screwdriver, and much more.


If you are looking for a quality but low-priced sawing machine for your projects, the Singer 4423 will not disappoint you, despite not being a computerized sewing machine it is still good. Don’t be afraid of the word “heavy-duty” this is not an industrial machine, but it can tackle thicker fabric like denim and leather.

If you are just starting, the singer heavy duty 4423 is perfect for you! You won’t even have to thread the needle on your own since the machine does that for you. The final choice is yours and we hope this article helped you make up your mind to choose the right machine for your specific needs.
