The best way to verify the dimensions of an impression made with a plastiform is to use a non-contact measurement procedure.
Indeed, most impressions being flexible or soft, contact processes will tend to deform the impression (more or less depending on the tool) during contact.
In order to achieve maximum accuracy in your measurements, it is therefore necessary to use an optical inspection tool. Measuring with an optical tool will ensure that the impression will not move at any time, and therefore, that its dimensions will remain unchanged during the inspection.
We recommend the use of a profile projector, vision system or scanning system to make the most of Plastiform dimensional impressions.
