Bending Acrylic Sheet With Heat Gun Temperature

To achieve this core temperature the former must calculate the temperature differential on both sheet surfaces.

Bending acrylic sheet with heat gun temperature.

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. Only that the operator is now forced to move the heat gun constantly along the bend line and flip over the polycarbonate sheet to ensure both sides get heated. Before you bend acrylic set it between 2 pieces of scrap wood and clamp them together with a vice. 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. 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. Principally using a heat gun to bend a polycarbonate sheet is the same as hot line bending. Ambient oven temperature also affects the heating cycle.

Temperature uniformity varies with heater model. You can see this in the video below. Bending polycarbonate sheet with a heat gun. Then aim a heat gun at the point on the acrylic you want to bend.

If it doesn t then you re just going to have to be quite diligent. Acrylic sheets are relatively inexpensive pretty and can be heat shaped very effectively. There are blades and tools made specifically for cutting heating and bending acrylic but marija shows. 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.
