Thick Sheet Thermoforming - Lesson 3 Effective Heating of the Plastic Sheet

Thick Sheet Thermoforming Training Program For more course information please visit This is a demo video from lesson 3. In the thermoforming process the plastic is heated twice once in the extruder and once in the thermoforming machine. This lesson covers the three main heating methods used in the thermoforming machine conduction convection and infrared. Control of heating in the thermoformer is key to good part quality. This section explains how plastic absorbs heat and how that affects the thermoforming process. This lesson expands on the infrared heating of the plastic sheet including emissivity view factor wavelength and absorption.,
