How to Mold Plexiglass | Our Pastimes

Cold Forming. 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.

Forming Lexan Sheet - practicalmachinist

Apr 01, 2004· Thread: Forming Lexan Sheet. I've used a break to bend 1/4 and 1/2 inch Lexan but it seems that if you go much past a 45 degree bend that you'll get stress fractures. Bending to 90 is the cold limit, go past that and it'll break. Use a heat gun and you can tie it in a knot if you want.

LEXAN 48 in. x 96 in. x .220 in. Clear Polycarbonate Sheet .

LEXAN sheet can be cold bent to tighter curves than are possible with acrylic. Cold forming of LEXAN sheet is acceptable for shapes hav- ing a radius of 100 times the material thickness or greater. Bends with radii less than 100 times the material thickness will require heat forming. This sheet is .22 so I wouldn't bend it more than 22" radii.

Lexan Polycarbonate Sheet - Total Plastics, Int'l

Based on high-performance Lexan™ polycarbonate resin, clear sheet products offer excellent clarity with attractive aesthetic properties and high impact strength. They are also easy to design and form. Opaque sheet products combine excellent impact performance and stiffness with ease of thermoforming or cold forming.


These include ambient, forming and mold temperatures, mold material, cooling system, part thickness and design geometry. However, since LEXAN sheet materials have a relatively high heat distortion temperature, formed parts can be removed from the mold at around 125 °C.

How to bend Lexan??? | The H.A.M.B.

Jul 23, 2009· Lexan can be bent cold in a sheet metal brake, and it does not crack. Most machine guarding systems that are required to be transparent are made from Lexan sheeting, sawn and bent to size, then glued together. To get a gradual bend, I think the "heat in oven and let droop over a form" method would probably work.

Formed Windows by Pro Glass-Manufacturers of Preformed .

Formed windows are better. By forming the window into the factory curved shape it becomes stronger preventing it from bowing in under strong wind forces. Formed windows also look better, and they fit better which even allows you to mount them the way the factory intended, e.g. adhesives or rubber seals. We make windows for most race cars.
