Key Mold Design & Process Tips for Quality

1. Choix des matériaux: Use SUS440C/SKD11/ASP23 for mold cores/cavities; apply TiN/CrN coatings for corrosion resistance.
2. Surface Finish: Mechanical polishing → CMP to reach Ra ≤ 0.001 μm; inspect with laser interferometers.
3. Process Control: Use Moldflow to optimize cooling channels; adopt injection-compression for thick-wall parts to reduce stress.
4. Quality Inspection: Use CMM, optical profilers, and interferometers to verify dimensions and surface accuracy post-machining/assembly.
