In particular temperature ranges PLEXIGLAS® can exist in various states of matter: solid, thermoelastic, or thermoplastic. This offers the advantage that you can easily form PLEXIGLAS® and give it a wide variety of shapes. Various possibilities exist for heating a PLEXIGLAS® sheet and then forming it: in air-flow ovens, by infrared radiation, with hot plates.
What happens if you don't heat a sheet of plexiglass?
If you don't apply heat evenly to the bend line of a sheet of plexiglass or acrylic you can create bubbles or scorch marks that cannot be removed. Do not keep your heat gun or torch too close to the plastic.
Can you use a heat tool to bend plexiglass?
You can use the same heat tool you use to bend plastic, to seal and neaten the cut edges of any plastic parts. Run your heat tool gently back and forth along a cut plastic edge to soften it just enough that it turns clear. In the photo below, you can see a poor bend in a sheet of 1/16-inch thick plexiglass.

Make sure any flammable or heat-sensitive material on your clamps is well away from where you will be applying heat to your plexiglass. The objective is to heat the plastic evenly along a line just in front of the straight edge of your clamped jig.
Can you shape plexiglass with heat?
Professionals often bend PERSPEX®️ (acrylic sheet) using a filament or resistance wire bending jig. They place the acrylic sheet over a long, thin filament with the bend line positioned precisely above the wire. When you heat acrylic to 160 degrees Celsius, it becomes soft and bends easily.
At what temperature does plexiglass soften?
between 210-220°FOPTIX acrylic sheet can be used continuously in a temperature range of 170-190°F. OPTIX acrylic sheet begins to soften between 210-220°F and starts to melt between 300-315°F. OPTIX acrylic sheet can withstand temperatures down to -20°F without noticeable changes in properties.

Can you curve plexiglass?
You can make bends of all types in very thin sheet acrylic, provided you work out the heat and time required for bending thin material and do not pass that point. Thin sheets are easily warped quite far away from the bend. For thinner sheets, you need to apply heat evenly to a very narrow line of the material.Nov 1, 2020
Can you heat plastic and bend it?
All thermoplastic synthetic materials can be bent when heated. Polycarbonate and PETG can also be bent (temper shaped) when cold. This technique involves forcing a plastic sheet into the desired shape in its cold state. The sheet is then heated up to a lower temperature (max.

How thick should plexiglass be for models?
Most scale models won't need bends in acrylic more than 1/16 inch thick. The difficulty with small projects, having tight bends close together, is control of the heat source so the adjoining curve isn't affected.
How to get bubbles out of test bends?
If you find bubbles or scorch marks occurring in your test bends, move your heat a bit faster along your bend line or hold it farther away from the surface of your sheet material. The distance and speed will be different depending on the thickness of the material you are working with.
How to heat a clamped jig?
To do so, pass your heat source at an even, slow speed along the line of plastic in front of the jig, keeping it far enough away that the heat source will not singe your wood jig.

Can heat resistant material cause mark off?
The heat resistant material will not have an effect. as long as the tool surface is cooler than your plastic, it will cool the plastic and cause mark off. A mirror polished tool, preheated to 80% of you plastic temp would be the way to go. Production tools for this type of work, I believe are almost always made of metal, steel or aluminum and often have internal cooling system with liquid.
Can you heat an oven with a heat gun?
Most household ovens have a fan system and the vapors given off are not extreme in volume, unless you burn it by getting it too hot too quickly. However, if you are sensitive to these things, then you shouldn't be heating it with a heat gun either.
