What Is Plastic Thermoforming?

Thermoforming is a widely used process for shaping polycarbonate sheets in various industries. It is commonly used in the manufacture of products such as dome skylights, motorcycle windshields, helmets, and more. Excelite polycarbonate sheets are designed for thermoforming on standard equipment, offering flexibility in shaping methods and applications.

There are several methods of thermoforming polycarbonate sheets, including drape forming, heat forming, and vacuum forming. Among these, vacuum forming and drape forming are the most frequently used because of their efficiency and flexibility.

When compared to acrylic sheets, polycarbonate sheets require more careful control during the thermoforming process because of their unique properties. It’s essential to dry polycarbonate sheets before thermoforming because of their water absorption rate of 0.3%. Failing to adequately dry the sheets can cause bubbling during the process.

One important consideration during thermoforming is the hard coating on polycarbonate sheets. While heating makes the polycarbonate sheet flexible, the hard coating is not similarly flexible and may crack under heat. If thermoforming is required for your project, consult with the Excelite team for a special hard coating designed to withstand this process.

Why Use Thermoforming for Polycarbonate?

Thermoforming is a versatile and cost-effective method for shaping polycarbonate sheets into various forms. It’s an excellent choice for projects that require complex shapes or large parts that can’t be achieved with other fabrication methods. Thermoforming is also beneficial for creating prototypes or small production runs, where the high tooling costs of other methods may not be justified.

Disadvantages of Thermoforming Polycarbonate

  • Limited to certain shapes: While thermoforming is versatile, it can’t be used to create complex or intricate shapes.
  • Requires skilled operators: Achieving precise forms requires skilled operators and careful control of the thermoforming process.
  • Potential for stress fractures: If not done correctly, thermoforming can cause stress fractures in the polycarbonate sheet.

Thermoforming Process for Polycarbonate

The thermoforming process involves heating the polycarbonate sheet until it becomes pliable. The sheet is then placed over a mold, and a vacuum is used to draw the sheet into the mold, forming it into the desired shape. The sheet is then cooled to harden it in its new shape. It’s important to control the heating and cooling process carefully to prevent stress fractures or deformations.

Types of Thermoforming Machines

  • Vacuum Forming Machines: These machines use a vacuum to draw the heated sheet into the mold. They are excellent for creating complex shapes and can be used for a wide range of parts.
  • Pressure Forming Machines: These machines use air pressure to force the heated sheet into the mold. They offer higher detail and precision than vacuum forming machines.
  • Drape Forming Machines: These machines use gravity to drape the heated sheet over the mold. They are excellent for creating large parts or parts with simple shapes.
