Inspection of Molds and Cores for Part Quality Assurance

Measurements of molds and cores, for example made of sand or ceramics, ensure the process quality. The measuring data of molds and cores from GOM’s ATOS system enables virtual assembly analysis of mold halves and cores, which serves for the inspection of parting surfaces regarding offset, fitting and form fit of mold halves and core clearance. In investment casting, the wall thickness of the ceramic mold can be inspected to estimate its quality and the formation of burrs.

  • Analysis of core allowance and core prints
  • Virtual assembly/die spotting
  • Inspection of molds and cores


3D data reduces rework time thanks to improved part quality. Furthermore, optical metrology secures wall thickness and cooling structures, e.g. water cooling jackets and cooling ducts. 3D measuring data provides information for root cause analysis to avoid defects and cracks in ceramic cores during wax molding. The check of cores and sand molds serves for wear control and analysis of pattern plates and tools.
