What Is A Styrofoam Cutter?

A styrofoam cutter, also known as a thermal saw, is an electronic device that can cut low melting point materials such as styrofoam.

What Are The Types Of Styrofoam Cutters?

Styrofoam cutters are used in many areas and therefore sometimes have completely different designs. The type of styrofoam cutter that is right for you depends entirely on the type of work you want to do with it.

There are several styrofoam cutters:

  • Pocket device

A very easy-to-use device. Small, the pocket-sized device is easy to carry around. Not suitable for precision work.

  • Tabletop unit

Easy enough to handle, the tabletop unit is comfortable to place on the surface. Not suitable for big jobs.

  • Cutter for insulation boards

Great for precision work in the construction industry. Has rather bulky handling. Not all insulation board cutters are suitable for making circular cuts.

What should you look for when buying the styrofoam cutter?

Styrofoam cutter refers to many tools that come in different sizes and designs depending on the application. You can decide which device will be the most suitable for your project, using the following criteria.

When buying should pay attention to the following:

  • Manufacturer

Some people may find this point superfluous, while others need it. There is no doubt that many tool manufacturers develop and produce thermal saws. Which brand you end up choosing depends on your personal preferences.

Thermal saws are electrical devices and must be safe, otherwise, you may be left with damage in the event of an accident.

Thermosaws are electrical devices and must be safe or you could be left with damage in the event of an accident.

  • Dimensions

Large devices are used for large components, but for small jobs, they are cumbersome and, at worst, not even suitable for your own project. Foam cutting devices usually come in different sizes, adapted to the appropriate application.

Verify which device best suits your needs by comparing the length and depth of the cut to the parts you are working on.

  • Cutting depth

Thicker pieces of material can pose problems for small thermal saws. To ensure a clean-cut, make sure that the depth of the cut of the cutter is at least as deep as the thickness of the material being cut.

  • Length of cut

If large pieces need to be cut straight through to the desired shape, long cutting lengths are necessary. Lines can be cut in the material along the cutting wire with equal precision.

If you need to cut large pieces of material in straight lines for your job, make sure that the cut length of the unit is long enough for your project.

  • Transformer

Thermal saws require a lot of currents (amps) for their low-voltage (volts) heating wire. If the unit is going to run with regular household electricity, the transformer must first reduce the voltage.

Be sure to purchase a model with a short-circuit-proof transformer to avoid possible accidents. Especially when more watts of power is to be achieved, safety should not be neglected.

Conclusions

Styrofoam cutters are often used for home use, especially when making models. Commercially, architects can’t avoid using styrofoam cutters when it comes to making styrofoam demonstration models, and even in the film industry, many props are still made from styrofoam. Thermal saws can also be useful in the construction industry.

Most new buildings today have insulation, including styrofoam. The styrofoam cutters, which were designed for use on construction sites, are adapted to make standard cuts accurately and quickly.

If you want to use styrofoam or similar materials as insulation for your home, a large insulation board cutter is recommended because it is designed to cut precise shapes quickly.

FAQs- Styrofoam Cutter

✅ What kind of power supply does a styrofoam cutter need?

You don’t need aviation scissors to cut sheet metal in a straight line. Tin snips are better for this task – look for a pair similar to scissors. Before you start cutting, use a permanent marker and a ruler or yardstick to clearly mark the cutting area.

The power of the transformer usually depends on the thickness and length of the heating wire, as well as the expected temperature. If you want to build a cutter for polystyrene yourself, a power supply with a 12 V output and 3 amps is enough. If you decide to buy a commercially available unit, the power supply is of course already included in the product.

✅ What vapors are produced when cutting styrofoam?

Styrene and carbon monoxide are two toxic substances that can be produced when Styrofoam is burned. However, normally no vapors should be produced when cutting normal Styrofoam.

It is usually sufficient to reach the melting point of the material for effective processing. If vapors do occur, it is advisable to turn down the output of the unit slightly.

✅ What are the alternatives to the styrofoam cutter?

Basically, anything that gives off heat can shape Styrofoam. Mechanical processing with sawing tools is also possible, but it does not give as good results because the material is often porous and brittle.

  • Soldering iron.
    An electrical device used for processing metals with low melting points.
  • Soldering gun.
    A soldering gun in the shape of a pistol. Suitable for rough work only.
  • Cutter for styrofoam with your own hands
    However, this is not recommended for beginners in the field of electrical engineering.

Keep in mind that all these alternatives are only partially suitable. Therefore, if you do not have any special requirements, but just want to cut polystyrene foam several times and with the same quality, it is also worth buying a suitable cutting device.
