Degrade the sheet if the heating cycle is exceeded.
Make your pressure on the acrylic as even as possible while you push.
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.

Bending acrylic is best done with a strip heater or line bender but you can use an ordinary oven set at 120 160c use a jig or former to get the angle correct.
One way of reducing stress induced cracking on the bend line is by the process of annealing.
Place the part of the acrylic to be bent just above the open door wait for it to soften enough and then bend it to the angle desired.
The acrylic sheet is laid over a long thin filament with the bending line just above the wire.
Over bend the sheet slightly to prevent memory and then let the sheet relax back into the form.
