ABSTRACT:
A process for checking the surface condition of a part, particularly in areas which are difficult to access, comprises making a rough preliminary imprint of the surface using an elastomeric material of medium precision in paste form and allowing the material to harden so that the preliminary imprint forms a supporting mold, casting a high precision elastomeric material, preferably in silicone based material, into the supporting mold and applying it to the surface to form an accurate imprint which is allowed to harden and, after removal, is inspected to determine the surface condition.
