ABSTRACT:
A device to evaluate the thermoformability of plastics using pressure, vacuum or both is provided. The device includes at least one set of adjustable radiant heater panels laid parallel to the plastic material, a non-contact temperature measuring device, a carriage to move the plastic heated to preset temperature to forming, where a forming die attached to an end of mechanical device moves downwards or upwards at an adjustable speed forcing the heated plastic material to conform to the outer shape of the die while providing the actual force required to push the hot plastic as function of time or forming distance. A processor under the control of software measures the thermoforming characteristics of the sample.
