As the acrylic heats up move the heat gun from side to side and steadily push on it with a piece of scrap wood to help it bend.
Bending acrylic sheet with heat gun temperature.
Sheet compared with about 10 to 12 minutes for air oven heating.
Using solvent based glues on laser cut extruded acrylic can cause cracking due to the internal stresses from temperature differences in the acrylic.
If it doesn t then you re just going to have to be quite diligent.
To achieve this core temperature the former must calculate the temperature differential on both sheet surfaces.
Before you bend acrylic set it between 2 pieces of scrap wood and clamp them together with a vice.
Acrylic sheets are relatively inexpensive pretty and can be heat shaped very effectively.
Principally using a heat gun to bend a polycarbonate sheet is the same as hot line bending.
You can see this in the video below.
Bending polycarbonate sheet with a heat gun.
To create bends for small scale projects in plexiglass perspex or acrylic 1 8 inch and thinner you can use a small torch butane kitchen torches work well a paint stripping heat gun or an embossing heat tool which is a wand that works very similarly to a paint stripping gun but using a smaller more directed heat flow with a smaller fan.
If your heat gun has temperature control set it to between 130 150 c or a low medium setting.
There are blades and tools made specifically for cutting heating and bending acrylic but marija shows.
To guard against cracking place the acrylic on a flat sheet of glass in a shop oven not the one in your kitchen at about 180ºf 82ºc for about 1 hour per mm thickness then let them air cool.
Temperature uniformity varies with heater model.
Then aim a heat gun at the point on the acrylic you want to bend.
Acrylic sheet heated from one side may vary from one to three minutes depending on the type of heater and the distance from the heating surface to the plexiglas acrylic.
