Can polyurethane foam be cut with a hot wire?
A: Polyurethane foam should not be cut with hot wire tools. It needs a ton of heat, gives off toxic fumes, and leaves a lot of melted plastic wherever it is cut. We recommend that the polyurethane foams only be cut with a blade or saw.
What kind of wire do you use for a styrofoam cutter?
NiChrome Wire (NiCr) is the optimal cutting wire choice for Foam cutting equipment for a variety of reasons, but particularly because it is resistant against corrosion and oxidation at very high temperature. The NiChrome cutting wire reaches the temperature of a few hundred Celcius degrees in few seconds.
Can you cut polyethylene foam?
One of the most common closed-cell foams, polyethylene has numerous densities which affect cell size, firmness, and flexibility. In its lowest densities, it has a fairly large and bubbly cell structure, which can impact how clean a cutting edge is. Because of this, we suggest against using scissors to cut polyethylene.
Should you wear a mask when cutting polystyrene?
Cutting tools are sharp and can cause injury. Seek medical attention immediately if you get cut. When using a power saw to cut Styrofoam, wear a dust mask. Power saws can create a “foam dust” that is similar to sawdust, but can be an irritant if inhaled.
What is the best tool to cut Styrofoam?
Cutting Styrofoam Manually. Use a blade for straight cuts. Bladed implements like knives, box cutters, precision blades (like X-acto knives) or hacksaws are great for cutting through styrofoam, especially if you don’t need to make any curved cuts.
Can you cut polystyrene with a hot knife?
A hot knife is our top choice for cutting Styrofoam. A heated knife is ideal for making small cuts and leaves minimal mess compared to a normal serrated knife. The key is to use a sawing motion when cutting instead of pushing straight down.
What is a hot wire cutter?
A hot wire cutter is a tool used to cut polystyrene foam. The device consists of a thin, taut metal wire, often made of nichrome alloy, which is heated via electrical resistance to approximately 200°C.
How do you cut polystyrene foam?
Use an electric kitchen knife, such as a carving knife or a fish fillet knife, to create clean cuts in Styrofoam. Place the electric knife on the foam along the desired cutting line. Do not exert pressure on the electric knife, but allow the serrated blades to gently cut through the Styrofoam.
What can I use instead of nichrome wire?
Nichrome is good, steel or stainless steel should also work ok and may be preferred if you need less heat and more strength.
What is the best gauge of nichrome wire for foam cutter?
16 gauge to 11 gauge is used for foam cutters to cut shapes such as molding because they are stiff enough to hold a shape rather than being straight. A 12″ piece of 14 gauge nichrome wire requires only 1.9 volts but almost 12 amps. Larger diameter wires are also used for very long cutters such as 8 or 10 feet.
What is a hot wire foam cutter?
A Hot Wire Foam Cutter is a electrical cutting tool used to cut or handle polystyrene / styrofoam (EPS, XPS) foams and similar materials.
What size NiCr wire do I need for my foam cutter?
Depepnding on the width of the foam cutter (i.e. length of the cutting wire) we use NiCr wires of the following diameters: 0.15, 0.25, 0.40 and 0.60 mm. Each Hot wire CNC foam cutter comes with a free cutting wire coil (100 g). Basic Hot wire CNC foam cutters come with the standard NiCr wire.
What hot wire tools do you supply for foam sculpting?
