Mold measurement involves a very wide range, including model mapping, mold design, mold processing, mold acceptance, mold repair testing, mold molding product batch testing and many other fields require high-precision dimensional measurement. The measurement object is mainly a plurality of geometric quantities or form and position tolerances, which has certain requirements for the equipment. For the mold with fine structure and small size, the traditional contact coordinate probe has low efficiency and is not suitable for such workpiece detection. The image measuring instrument can use the zoom lens to clearly observe the mold details, which is convenient for precision measurement tasks such as defects and size detection.

The mold forming parts are characterized by large quantity and high measurement efficiency. Traditional contact coordinate measuring machine, joint arm measuring machine, large-size laser tracker and other instruments are also widely used in the field of mold measurement, but there is no good solution in the face of fine structure, thin-walled workpieces, tiny injection parts, and batch rapid measurement. The image measuring instrument with the CCD face array sensor, non-contact measurement characteristics, it can efficiently complete the measurement of the workpiece that can not be contacted, easy to deform, small shape, in this respect image measuring instrument has an absolute advantage.
