Forming plexiglass sheet. We can say that it is a superhero because it is approximately two hundred times stronger than a normal glass which makes it virtually unbreakable thus it is used in windows motorbike fairings. We re not that good at it come watch. I can t recommend for. Continue to direct the heat jet back and forth along the bend line until the acrylic sheet fits into the form at the correct angle.

Hold the sheet in position for a few minutes allowing it to cool and re harden. A mold any object shape you can press the acrylic into to give it shape mallet and or a peen for shaping caution i ve only tried this in an electric oven. Acrylic oven baking sheet aluminum foil timer felt for handling the acrylic and to prevent scratches tools for forming tools for forming may include. Release mechanism for hanging plexiglas acrylic sheets in heating ovens.

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. 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. For thicker sheets it will take longer and for thinner sheets it will take less time. Over bend the sheet slightly to prevent memory and then let the sheet relax back into the form.

Note that the minimum radius of the bend you create is 180 times the thickness of the plexiglass sheet. 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. This device can reduce appreciably the labor required for clamping and unclamping sheets preparatory to forming. For thicker acrylic you will need to use a metal bar clamped very securely and you may only be able to work with narrow strips of material as your heat source may not be able to heat wider areas of thick material.

Modify the timing as necessary. Attempting to create a smaller radius would snap the sheet. It can also shorten the time required to transport the heated sheet from the oven to the forming equipment thus minimizing the possibility of cold forming. Today we re using a line bender to form some acrylic for our new cnc dust shroud.

Diy soda fountain machine. This article uses a sheet about 1 4 thick so all times are about 10 to 15 minutes per step. The only major variable that can affect the forming process is the thickness of the plastic sheet.
