LIRAS Optical has internally developed its own thermoforming technique, different from traditional processes, which allows for complex shapes to be obtained from flat polycarbonate and PMMA sheets with constant thicknesses throughout the component. The result is a transparent component with preserved optical quality even on curved and complex geometries — an essential requirement for automotive, aeronautical, and nautical applications.
Hot bending is applied for components with simple or moderate curvature, with high repeatability and short cycle times. Both techniques handle polycarbonate, PMMA, and technical plastic materials in various thicknesses and formats.
