Precision Mold Parts For Measurement

With the development of tungsten steel precision mold parts manufacturing industry, the development of mold measurement technology has followed suit. Different measuring technologies and different measuring equipments came into being according to the different characteristics of mold manufacturing. From digital surveying and mapping involved in the early stage of mold design, to measurement of mold processing procedures, mold repair measurement, mold acceptance measurement and later mold repair measurement; from electronic small size molds to automotive medium and large molds and large aerospace industries Mold measurement, high-precision measurement equipment is everywhere.

The measuring equipment used for the quality inspection of precision mold parts not only includes the classic fixed high-precision three-coordinate measuring machine, but also because of the characteristics of mold manufacturing, a variety of measuring equipment suitable for on-line application in the field, such as portable articulated arm measuring machines, efficient white light Measuring equipment such as measuring machines and large-size laser trackers have also appeared on the scene, and meet the testing requirements of mold products through detection technologies such as contact and non-contact measurement, image and laser scanning, and photogrammetry.

A typical mold enterprise, in addition to the production and manufacture of molds, will also involve the manufacture of some check fixtures, jigs and ordinary machined parts. In this case, a fixed measuring machine with high accuracy, strong function and good versatility has become the classic measuring equipment preferred by most mold companies for quality inspection.

The measurement requirements of precision mold parts usually include the specified point measurement of the control surface, the diameter and position measurement of the assembly and positioning holes, etc., and often the profile of the measurement and surface lines. At this time, the high-precision, automatic, and point-to-point contact measurement capabilities of the stationary measuring machine are extremely applicable. If it is required to directly compare the mold workpiece with the point cloud of its CAD model, or survey the metal mold parts, the fixed measuring machine can also use the contact continuous scanning probe or non-contact laser scanning probe to achieve high Efficient, high-density point cloud scanning measurement. It should be noted here that because of different measurement structures and measurement principles, the accuracy of contact measurement is usually better than the accuracy of non-contact measurement.
