[PH Case Study] Extending the Lifespan of Aluminum Die Casting Molds

Solving the issue of increased mold replacement frequency due to heat cracks and melting!

We would like to introduce a case where issues related to heat checks and melting, which are the main forms of damage to aluminum die-casting molds, were resolved through composite surface treatment. By using ultra-precision peening with minimal changes in surface roughness and without generating a compound layer, we suppressed the occurrence and progression of heat cracks. It is possible to improve aluminum attack resistance with a highly heat-resistant PVD coating film. [Case Summary (Partial)] ■Challenges and Background Faced by the Customer - Increased frequency of mold effectiveness due to heat cracks and melting - Increased costs for mold replacement work and mold manufacturing due to production line stoppages ■Our Solution - Changed from TiAl-based PVD coating film to composite surface treatment plasma hard - Achieved a reduction in melting and heat cracks, resulting in a mold lifespan that is over four times longer *For more details, please download the PDF or feel free to contact us.
