Acrylic is a widely used material in vacuum forming and thermoforming due to its strength, versatility, and quality finish. Waveform can create a wide range of custom parts and shapes from acrylic sheet stock. From prototypes to full-scale manufacturing, our skilled team is ready to support you at every stage of your project.
Acrylic is a transparent or translucent thermoplastic frequently used in highly cosmetic applications, where a high quality glossy surface finish and a degree of light transmission is desired. It has excellent weatherability and optical properties, making it suitable for a wide range of applications.
What is Acrylic Vacuum Forming?
Acrylic vacuum forming is a manufacturing process where a heated sheet of acrylic plastic is drawn down over a mold using vacuum, pulling the softened plastic tightly against the mold’s contours. Once cooled, the acrylic sheet retains the mold’s shape, creating the desired part shape. The part is then typically trimmed and deburred. The type and quality of tooling (molds) used to create acrylic parts are often critical in the thermoforming process, as that can impact part clarity and surface finish.
Waveform offers a variety of Acrylic sheet grades for our vacuum forming and thermoforming processes. Typical material options include a range of standard colours, the degree of transparency and impact of UV enhanced. The exact material spec chosen depends on your project’s requirements.
