• What is one of the most popular methods of shaping plastic materials like acrylic?

  Folding (bending) it on a ‘strip heater’
• What is the process of folding acrylic on a strip heater called?

  Line Bending
• What type of process is line bending?

  A thermoforming process
• How does line bending work?

  By heating a thermoplastic sheet over a strip heater until it becomes soft and pliable, then bending it
• What can thermoplastics be bent to?

  Any angle
• What tools can be used to bend thermoplastics?

  A jig or a former
• What can be done if the angle of bending is not critical?

  Bend the thermoplastic sheet by hand and hold it until it cools
