Large-scale mold manufacturing is completely guaranteed by processing equipment, without testing. The problem is measured by the online probe installed on the processing equipment, and the accuracy and stability of the data cannot be guaranteed. If there is a problem with the mold, use the articular arm or scanner to simply confirm the problem point and then process it. The data given simply cannot be directly used to accurately modify the mold. In order to solve the problem of precision detection of large molds and gauges, help enterprises to achieve high efficiency mass production, IMS large travel three dimensional, plus advanced measurement software technology can be compatible with a variety of measurement software programs in the market, change the traditional detection method of large molds, is the preferred equipment for large automotive mold industry.
