Mold production carries strict dimensional tolerance standards, and mismatched measuring equipment will generate batches of defective mold parts and bring huge economic loss. Many quality supervisors struggle to find a video measuring machine that fits their mold size and precision demands. This article sorts out practical selection standards accumulated from decades of metrology service experience, helping manufacturing users lock ideal measuring equipment without blind trial and error.
Precision acts as the core index to judge whether a video measuring machine adapts to mold inspection. Most precision molds require micron level measurement error control, so users need to focus on linear accuracy parameters of the equipment. Small plastic molds with tiny concave and convex structures need manual video measuring machine equipped with high resolution lens, while large die casting molds demand CNC video measuring machine with extended measuring stroke. Lens configuration also decides the identification ability of micro mold features, low resolution lens cannot capture subtle dimensional changes of miniature mold cavities.
Stroke range is another non-negotiable factor during video measuring machine selection. Small injection molds within 300mm length can adopt compact desktop video measuring machine, which saves workshop space and reduces procurement cost. Large automotive mold exceeding 800mm length requires large stroke CNC video measuring machine to complete full outline scanning without secondary clamping. Improper stroke selection will force repeated workpiece repositioning, which adds extra inspection time and introduces manual operation errors.
Software compatibility and automatic measuring functions directly affect mold workshop working efficiency. Mature video measuring machine supports one key batch measurement for multiple identical mold samples, automatically recording dimension data and generating inspection reports. Entry level measuring equipment only supports single manual measurement, which cannot satisfy mass mold delivery inspection demands. Stable measuring software also supports data export to mainstream industrial management systems, facilitating quality data archiving and traceability for mold manufacturers.
