Cold Bending Acrylic Sheet

It is given by multiplying the thickness of the sheet by 100 i e.

Cold bending acrylic sheet. To bend sheet plastic and acrylic you will need. This radius is applied in all cold bending procedures. The recommended radius of curvature should be a value greater than 180 times the thickness of the sheet for plexiglas g sheet and 300 times the thickness for plexiglas mc sheet see table below recommended minimum radii of curvature for cold formed plexiglas. Be sure that the marked line is above the heating element.

Minimum cold forming radius sheet thickness x 100. Chemically spectar is similar to the pete used to make disposable drink bottles and is commonly abbreviated as petg. Forming but is viable for bending sheet thicknesses of up to about two inches. Turn the sheet of acrylic over on the heating element every 30 60 seconds in order to avoid damaging it.

Wear gloves as you do this to avoid burning your hands. The two best tools for this are a small butane torch the type used in the kitchen work well or you can also use an embossing heat tool used by card makers and scrapbookers to melt and apply embossing powders. Spectar supposedly looks and handles much like acrylic but with the surprising property that it can be cold formed without breaking or whitening and exhibits a memory effect holding a cold bend until reheated. In the image above the values are all in inches but the principle often holds even if the units are in mm.

A typical forced circulation air oven is shown. Set the sheet of acrylic across the rests on the strip heater and turn it on. Cold forming plexiglas sheet can be cold formed bent at room temperature in a smooth arc and held to a radius by forcing the material into a curved channel support. Plexiglas sheet cold forming.
