These benders are compatible with plastics such as acrylic, polyethylene, polypropylene, polycarbonate, PVC, CPVC, ABS, and Kydex. Place a sheet between the heating bars to soften it. Heating time varies between 30 seconds and 12 minutes based on material type and thickness. Use wood or metal supports (not included) under the sheet during heating. V-groove attachment creates sharp, nonradius 90° bends in polypropylene and polyethylene sheets by melting a deep groove in the material. Excess material forms a raised edge along the inside of the bend to reinforce the angle.

Benders with a maximum temperature of 800° have a steel frame and must be used with a voltage adjuster (not included). The adjuster controls the heating power over a wide range for more consistent and precise temperature adjustment than other steel-frame benders.

Benders with a maximum temperature of 400° include a dial for smooth and precise temperature adjustments. All have an aluminum frame.
