Thermoforming involves stretching of rubbery solid plastic sheet. When force is applied to any material, it stretches or elongates. The amount that it stretches depends on the amount of force per unit area, or ‘stress,’ applied to the sheet, the nature of the material and its temperature. Process – Cycle Time.
