Singer 4423 Review

This sewing machine has been made with a heavy-duty interior frame. The construction of this sewing unit provides the necessary stability for skip-free sewing.

It also provides durability. Singer 4423 includes a stainless steel bedplate which offers a smooth fabric feed and enables even sewing. Additionally, it’s loaded with a powerful motor.

This unit comes with 23 built-in sewing stitches, an automatic needle threader, and a top drop-in bobbin system. It also has an extra-high sewing speed which can deliver 1,100 stitches per minute.

This is a huge boost considering that other Singer sewing machines like the 7258 Stylist can only sew up to 750 stitches per minute. Let’s take a look at some of the key features.

Stainless Steel Bedplate

The stainless steel bedplate of this sewing machine delivers the effortless fabric feed and ensures even sewing. It’s one of my favourite features.

Bobbin Threading

The bobbin system in Singer 4423 is simple to load and drop-in system. Therefore, bobbin threading isn’t a big deal with this sewing machine. This system saves you time and effort.


In this sewing unit, there’s a feature of 1-step and fully automated buttonhole which would provide you with the professional outcome at the push of a button.

Built-In Stitches

As the name of the machine suggests, 4423 comes with 23 inbuilt patterns including 6 basic patterns, 12 decorative stitches, and 4 stretch stitches. This makes this unit ideal for clothing construction, crafts, etc.

Drop Feed

The drop feed option would offer you with free-motion sewing for the sake of creative top-stitching. It’s another favourite feature of mine.

Stronger Motor

4423 has been loaded with a 60% stronger motor when compared with other sewing machines for home use. It’s a heavy-duty sewing unit that can handle many tasks.

Therefore, it’s perfect for sewing heavyweight fabrics with ease. This is a very important feature because it makes this model one of the best sewing machines in the market.

Needle Positions

Singer 4423 has 3 needle positions which could be switched according to your specific need and the type of project like top-stitching, inserting zippers, etc.

Needle Tension

4423 sewing unit can be regulated for needle tension to ensure that your stitch quality is steady. This is a great feature loved by many sewers worldwide.

Free Arm and Onboard Storage

There’s a free arm which would provide sewers with access to hard-to-reach places like collars, sleeves, and cuffs. There’s also convenient onboard storage of accessories.

Automations on Different Levels

Singer 4423 has different automated features. For instance, there’s an automatic needle threader which would thread the eye of the needle automatically.

There’s also an automated 1-step buttonhole which would create buttonholes in a single step. 4423 also has an option to sew in reverse automatically which is pretty impressive.

It’s also loaded with an automated presser foot for pressure control by which the amount of force that is implied on the fabric would be automatically controlled.

Lastly, there’s a computerized bobbin winding grasp. This makes bobbin winding simpler by detaching your needle bar during bobbin winding automatically.

It’s also suitable for intermediate and advanced sewers. Surprisingly, this sewing unit manages to please everyone. It has been constructed flawlessly from the ground up by an expert team.

This small accessory tray can be easily removed to uncover the free arm. Lastly, Singer 4423 comes with an automatic needle threader enabling automatic needle threading.

The automatic features save you a lot of nerves and time. And makes this sewing machine easier to use for everyone. Who doesn’t want an automatic needle threader?

How to Thread Singer 4423 Sewing Machine?

After following the threading path displayed right on the sewing unit, the automatic needle threader will help you thread the eye of the needle effortlessly without eye strain.

Or frustration. The automatic needle threader is one of the best features on Singer 4423. It prevents the straining of your eyes and saves you the effort of threading the needle yourself.

What is the Difference Between Singer 4423 and 4432?

They’re identical. They have the same size and type of motor. And will sew at about the same speed and sound level.

The biggest difference lies in the number of stitches. 4423 has 23 inbuilt stitches including 12 decorative patterns, 4 stretch patterns, 6 basic patterns and 1 buttonhole.

4432 comes with 32 inbuilt stitches including 18 decorative patterns, 7 stretch patterns, 6 basic patterns and 1 buttonhole. Also, the Singer 4432 sewing machine is costlier.

What Bobbin Does Singer 4423 Use?

If you want to get the most from your Singer 4423, make sure that you’re utilizing the right Singer 4423 bobbins. This unit comes with regular plastic Class 15 bobbins.

Stick with those when you’re restocking additional bobbins. The bobbin size is Class 15 (20mm x 11mm). The Class 15J is a bit curved and may not work well in your unit.

What Size Needles for Singer 4423?

This sewing machine comes with a Singer Style 2020, size 90/14 needle preinstalled in the machine. Use any Singer or Universale needle. The size depends on your fabric.

The type, on the other hand, depends on knits, wovens, etc. This unit can sew most heavy fabrics with proper needle and machine settings. Utilizing the right needle is crucial.

It will affect the quality of your stitching. And can boost the capabilities of the sewing machine. Use only Singer or Inspira needles, as using other brands can cause issues.

How to Change Needle Singer 4423?

Change the needle regularly, especially if you notice signs of wear or if it’s causing issues. Always utilize Singer brand needles for the best sewing results. Otherwise, you might face problems.

To change the needle, turn the power switch to off before removing or inserting the needle. Loosen the needle clamp screw and tighten again after inserting the new Singer sewing needle.

The flat side of the shaft should be towards the back. Insert the needle as fas up as it will go. The needle must be in perfect condition. Issues might happen with bent, damaged or blunt needles.

How to Oil Singer 4423 Sewing Machine?

There are no cleaning or oiling instructions in the user manual. There are no noticeable oiling points on the sewing machine either.

You will probably have to talk to a Singer dealer to discover that information. It probably doesn’t require oiling but maintenance by a repairman is always welcome.

Also, regular cleaning and good needles and quality thread are necessary.

4423 arrives pre-lubricated at the factory. You can put 2 to 3 drops of sewing machine oil in the bobbin case area, as well as on the needle bar.

This won’t harm your sewing unit. You can also put a couple of drops (2 to 3) on the handwheel where it meets the side of the sewing unit.

Who is This Sewing Machine for?

This sewing machine is perfect for people who want to purchase a decent heavy duty sewing unit that’s also affordable. It’s also great for someone who is planning to sew thick fabrics.

If you’re on the lookout for a strong sewing machine and do both regular and heavy-duty sewing, this is the sewing machine for you. It’s perfect for people who want a sturdy sewing machine.

It’s also suitable for those who don’t mind a restricted number of inbuilt stitches. As you probably know, this sewing machine comes with 23 inbuilt sewing stitches including 1 buttonhole.

However, it’s not a good choice for professional heavy-duty sewers. 4423 isn’t able to handle industrial level heavy-duty projects. It’s not suitable for DIY crafters due to the limited number of stitches.

If you’re planning to sew multiple layers of dense fabrics regularly, consider other heavy-duty machines. This one isn’t able to handle multiple layers of super dense fabric.

If you find it hard to control the speed of a sewing unit utilizing the foot pedal alone, don’t buy this unit. It has no speed control slider. Therefore, you will have to utilize the foot pedal.

Where to Buy Singer 4423 Sewing Machine?

If you’re determined to buy Singer 4423, you can find it at the local sewing speciality stores. It’s available at Amazon and Sewing Machines Plus. You can find good deals for Singer 4423 in store.

I have only good words on this brand and their Singer 4423 sewing machine. It’s not ideal. However, it’s still a decent heavy-duty sewing machine. It’s budget-friendly and beginner-friendly.

If you’re looking for a sewing machine that will allow you to sew heavy-duty fabrics with great ease and boost your skills, look no further than Singer 4423. It’s fast, powerful and super-versatile.
