Plastic Line bending

• What is the material used for line bending?

  Thermoplastic material
• How is the thermoplastic sheet prepared for bending?

  It is heated in a strip along its length
• What happens to the thermoplastic when heated?

  It becomes flexible for bending
• How can the heated thermoplastic be shaped?

  It can be bent to the required shape
• What is one method to bend the thermoplastic material?

  By hand or using a jig
• What happens once the material cools after bending?

  It retains the formed shape
• What are the advantages of line bending thermoplastic materials?

  • Efficient straight bends can be achieved quickly
  • Low cost for setting up equipment
  • No tooling is required for the process
• What is a disadvantage of line bending thermoplastic materials?

  It is not an automated process
• What does the operator need to check during the bending process?

  When the material is flexible enough for bending
• What risk is associated with the plastic during bending?

  It can overheat and burn easily
• What are some applications of line bending thermoplastic materials?

  • Making display units
  • Creating picture frames
  • Holding newspapers, magazines, or advertising leaflets
• How should the plastic sheet be held during heating?

  By holding the line of bend over the heater
• What should be done with thicker sheets during the bending process?


  They should be removed from the heater periodically
• What is the purpose of turning the heater over time?

  To give time for heat to conduct through the material
• What can be used to achieve the correct angle during bending?

  A mould can be used
• What is the angle achieved with an acrylic line bending process?

  Correct angle for bending
• What is the purpose of using a jig in line bending?

  To achieve precise bending angles
• What are ways to make holes in plastic? (before or after bending)

  1. Drilling- Use a drill to carefully make holes in the plastic sheet

  2. Laser Cutting - For neat, Accurate holes (done before bending)

  3. Centre Punch + Drill - Mark the hole first, then drill.

  4. CNC Machine - if precision is needed, especially in mass production
