Cold Bending Plastic Sheets

Hot bending polycarbonate sheet.

Cold bending plastic sheets. Well this is the opposite of the cold bending polycarbonate sheet. Some materials can even be cold bent using a press brake the same machine used for bending metal. Depending on the thickness of the material most plastics can be bent in a gradual radius without negatively affecting the integrity of the material. Cold bending is further possible with more types of polyester.

Be sure that the marked line is above the heating element. The process of cold bending of plastic sheets is the same as bending metal but since plastic is a vivid material than metal it causes more problems.

Curved polycarbonate sheet on swimming pool enclosure in the formation of such a shape the significance of the cold forming radius comes into play. Set up plastic or acrylic sheet in a simple bending jig. To view this site you must enable javascript or upgrade to a javascript capable browser. However cold bending is quicker and more favourable than hot bending.

Use long thin 1 inch or so in width test strips to practice your technique and learn how your particular heat source affects your chosen thickness of plastic. Alternatively in case you don t want to cold bend polycarbonate sheet apply heat. When you heat acrylic to 160 degrees celsius it becomes soft and bends easily. This takes us to another important fabrication process.

Wear gloves as you do this to avoid burning your hands. Tensions arise during bending and the sheet may straighten out. To set up your plastic or acrylic sheet to bend simple curves for your miniature and model projects you need to first remove the protective covering from the material you wish to bend. Cold bending some thermoplastic materials can be cold bent without the need to apply heat.

After bending heat the acrylic on the outside of the fold line briefly to seal it properly. It s advisable to proceed with care. Turn the sheet of acrylic over on the heating element every 30 60 seconds in order to avoid damaging it. 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.

They place the acrylic sheet over a long thin filament with the bend line positioned precisely above the wire. Bend the acrylic slowly and gently to avoid tearing the material on the exterior of the fold. Cold line bending polycarbonate sheet is basically a prelude to fabrication process. Set the sheet of acrylic across the rests on the strip heater and turn it on.
