When you feel that your sheet is allowing you to push up evenly on it, remove your heat source and set it safely aside on a stand or heat-resistant surface; the end of your tool will be hot! Hold the sheet material evenly with both hands (both in protective gloves) and push the sheet up gently bending it against the line of the jig as shown in the photo above. You must use two hands to do this with even pressure, or your material will twist slightly as you bend it unless you are working with a very thin, narrow strip. here

You can use the same heat tool you use to bend plastic, to seal and neaten the cut edges of any plastic parts. Run your heat tool gently back and forth along a cut plastic edge to soften it just enough that it turns clear. here

Lay your plastic on your heat-safe work surface and place a scrap of strip wood over your plastic roughly 1/4 of an inch in front of where you want your bend to be. This will be somewhat determined by the thickness of your plastic, as thicker plastic will need a wider radius curve for most bends. Use a ruler to check that your sheet of plexiglass or plastic is held squarely clamped beneath your strip wood jig. The strip wood will restrict the application of heat (it will catch fire if you overheat the wood) and will prevent the plastic beneath it from becoming soft enough to bend.

Try to keep the heat source at a right angle to your sheet of plastic/plexiglass. If you turn your heat source as you pass across the acrylic, the heat won't be evenly applied across the entire width of your sheet. more

You can make bends of all types in very thin sheet acrylic, provided you work out the heat and time required for bending thin material and do not pass that point. Thin sheets are easily warped quite far away from the bend. For thinner sheets, you need to apply heat evenly to a very narrow line of the material. If you do not have a heat source that will work for thin materials, try the method shown for heat welding plastic, using a metal kitchen spatula or blade heated against an iron, then pressed against the material.

Sometimes, it is necessary to bend metal when heat is not available. In such cases, secure the metal before bending it. Follow the same procedure as bending hot metal, but omit the heating and cooling steps. If the material is brass, you may not want to bend it while it's cold at all; it can shatter or crack. Never bend any rod or rectangular bar of cold metal past a 60-degree angle. Anything more most likely will crack the metal. If you have a vise, use it to secure the metal, then use tongs to hold the metal and bend it. If you have an anvil, you can use its horn as a template and bend the metal around it. here

Metal's crystalline structure makes it more malleable when heated. It can easily be bent when it's very hot. Sources you can use to heat metal include: propane or oxygen-acetylene torches, a forge and a hot fire. Some heat sources, however, may be too hot for a particular metal. For steel or aluminum, heat the metal until it is red hot. For most other metals, it usually is not necessary to use heat, but if you have to, heat them slightly and avoid heating metals, such as brass or copper, which melt very easily. Once, the metal is heated, use a hammer or tongs to beat a bend into the metal. This can be done with shear strength or with a mechanical aid, such as a press. When bending a hot metal, apply pressure to as small an area as possible to minimize strain on the metal. If you use a hammer, try to bend the metal around a template; hot metal is very easy to over-bend. Once the metal has been bent, let it cool slowly, so the crystals have time to reorganize and stay hard. here

Whether you are starting on a career as a blacksmith or simply repairing a car or building, it can be helpful to know the dynamics of bending metal. If you keep in mind a few basic principles, you can learn the best way to bend metal.

[madtrade]

Wear heavy gloves and eye protection when bending metal. Do not touch hot metal with your hands. Use only tongs or a vise. If you know how to quench (rapidly cool hot metal in cold water or oil) metal and feel it is necessary after heating it, you may want to use more protection. Quenching can cause metal to shatter. Know the type of metal you are using before heating it. Never heat metals that are galvanized or that have zinc in them--unless you have access to a respirator that is certified to filter out poisonous gases. A simple facemask is not sufficient to block zinc fumes, which will kill you. more

BriskHeat RH plastic bending strip heaters are a flexible strip heater that provides a fast, easy, and cost effective way to bend, shape, or form acrylic and other thermoplastic sheet products. Using a BriskHeat bending strip heater as a heating element you can quickly build a plastic line bending tool for safe, reliable, and efficient bends.

Plastic bending is common for makers, sign makers, inventors, display manufacturers, fixture manufacturers, and more. These users often need to make custom bends in sheet acrylic products. One of the most useful properties of acrylic is its thermo-formability. As it becomes warm it softens and can be bent or formed into any shape imaginable. The typical forming temperature range of most acrylic sheet plastics is 275°F to 350°F (135°C to 177°C). A consistent and controlled heat source is necessary so that the bends are smooth and the finished parts are aesthetically pleasing.

[gerders104]

BriskHeat’s high temperature heating tape distributes heat uniformly throughout the tape to apply a consistent, controlled heat to the bend area without affecting the surrounding area. This provides a clean, uniform bend without hot-spots that can damage acrylics. The heating element is incredibly flexible and can be configured for straight or complex geometries for making custom bends. In addition, they include a cord and plug for a connection to an electrical outlet or temperature controlling device. more

What temperature does acrylic plastic soften?

[ledskof]

A: While acrylic softens at higher temperatures, it does not actually melt until it reaches 320 °F (160 °C). Therefore, normal household use does not risk melting acrylic. Hot stovetop items should only be placed on an acrylic tabletop surface using a protective trivet or other padding, preferably with rubber cushions.

[Beelzebuddy]

Furthermore, what temperature does plexiglass need to be to bend? While strip heaters employing hotter elements than 800°F can be used for bending Plexiglas® MC acrylic sheet, the risk of bubbling increases as the element temperature increases. For example, if the sheet is heated 15 seconds too long with a glowing red element (about 1500°F), bubbling is very likely. more

Dr. Leo Baekeland patented the first plastic in 1909. It was a phenol-formaldehyde plastic, which was able to be heated and then formed into shape while under pressure. Acrylic resins were first produced in 1931 for industrial uses and were introduced as sheet plastic, or early plexiglass, in 1936. It was first used as windows in war planes in World War II and is now commonly used in households.

Plexiglass can withstand a wide range of temperature differences, but it does respond to prolonged exposure to heat. Sustained temperatures over 180 to 200 degrees F will cause the plexiglass to soften and lose its shape.

One weakness of plexiglass is the ability for certain chemicals to damage it. These chemicals include gasoline, certain solvents, organic acids and lacquer thinners. Plexiglass is not affected by gasoline quickly, but after seven days of exposure the plexiglass shows some effect. Solvents such as methylene chloride, benzene and turpentine cause immediate damage. Organic acids such as acetic acid at 50 percent concentration also cause immediate effects. Lacquer thinners also have immediate effects on the plexiglass. here
