How to Mold Plexiglass
- 1). Force the plexiglass into the desired shape. Note that the minimum radius of the bend you create is 180 times the thickness of the plexiglass sheet. For instance, the smallest complete circle you could form with a sheet of plexiglass 1/32 inch thick would have a radius of 5.6 inches. Attempting to create a smaller radius would snap the sheet.
- 2). Secure the plexiglass in place with round head wood screws.
- 3). Try heat forming for a more permanent and flexible method of plexiglass molding.
- 1). Preheat the oven to 250 degrees F.
- 2). Place a plexiglass sheet on large pan and place on the middle oven rack. The large pan prevents the plexiglass from coming into contact with the hot rack, which can distort the plexiglass due to uneven heating.
- 3). Heat for approximately five minutes.
- 4). Pull the pan out of the oven with the cotton gloves. The heated plexiglass is now ready for molding.
- 5). Mold the plexiglass into the desired shape. Work quickly as the plexiglass will become less malleable as it cools.
- 6). Place your plexiglass in the refrigerator to set the shape. You can repeat this process as many times as needed.
