This video is about bending and thermoforming king plastic polymer sheets. 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. After bending heat the acrylic on the outside of the fold line briefly to seal it properly. This takes us to another important fabrication process.

When you heat acrylic to 160 degrees celsius it becomes soft and bends easily. Depending on the thickness of the material most plastics can be bent in a gradual radius without negatively affecting the integrity of the material.

Chemically spectar is similar to the pete used to make disposable drink bottles and is commonly abbreviated as petg. Curved polycarbonate sheet on swimming pool enclosure in the formation of such a shape the significance of the cold forming radius comes into play. 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.

Set the sheet of acrylic across the rests on the strip heater and turn it on. As could be inferred from its name cold curving is the process of bending the whole polycarbonate sheet to create a dome or an arch. Set up plastic or acrylic sheet in a simple bending jig.
