Improvement of lifespan and cost reduction through ultra-hard chipping countermeasures / DK Cryo Process
Even ultra-hard materials can chip... There may be ways to counteract that chipping.
It is often said on-site: "Since it's carbide, chipping is inevitable." While it is true that high hardness makes chipping more likely, are you giving up on improvement by saying "it can't be helped"? → In fact, that chipping may be preventable. ■ An option to make chipping "less likely to occur" One of these is the DK Cryo Process. By treating mold components, we can: - Suppress the occurrence of chipping - Reduce replacement frequency - Achieve stable lifespan From "replace when chipped" to "use until the end." We have also confirmed actual results of chipping suppression and lifespan improvement with carbide (KD10). First, please check the case study materials.

basic information
**Main Features** ■ Process compatibility independent of processing timing Can be added to existing heat treatment processes such as quenching and tempering. Applicable to coated parts and parts in use, allowing for minimal changes to the process during implementation. ■ Extended tool and mold lifespan (up to 7 times longer) Contributes to the extension of tool and mold life by suppressing chipping and wear. The effectiveness has been confirmed through various demonstration tests. ■ Improved dimensional stability (within ±0.01mm) Reduces residual stress through microstructure stabilization via cryogenic treatment. Helps suppress dimensional changes during use, contributing to stable precision maintenance. *Effects may vary depending on material, shape, and usage conditions. *For more details, please refer to the documentation or feel free to contact us.

Detailed information
-
The lifespan of ultra-hard (KD10) punches has been confirmed to be approximately 1.4 times longer. At the point of 140,000 shots, 2 untreated items are needed, while 1 treated item suffices → Achieving approximately 45% cost reduction. Furthermore, even with long-term use, → Approximately 21.4% cost reduction is expected. By suppressing chipping, - Reduces the occurrence of chipping - Limits the frequency of replacements - Stabilizes lifespan Improvement effects have also been confirmed in ultra-hard components.
