Manufactured to production-level industrial standards, these high-precision reference models are integrally formed using 5-axis precision machining equipment, strictly based on frozen final Class-A surface data. Finished product accuracy is consistently controlled within ±0.3mm, serving as the core reference for vehicle engineering development, mold development, tooling fabrication, and production quality inspection.
All Class-A master models undergo full-scale dimensional inspection using vehicle-level CMM equipment, with 100% data verification, recording, and traceability for critical surfaces, assembly dimensions, and hole/edge boundaries, completely eliminating dimensional deviations and assembly errors. Provides an accurate, reliable, and traceable physical benchmark for subsequent reverse validation, engineering benchmarking, and the establishment of production tolerance systems, meeting the stringent pre-production development standards of OEMs.
