For those troubled by the lifespan and chipping of mold parts and cutting tools, we introduce the concept of deep cryogenic treatment "DK Cryo Process."
The DK Cryo Process is a deep cooling temperature treatment applied to mold components and cutting tools. This treatment is not merely aimed at improving hardness or toughness. It focuses on the stress state at the boundaries between different microstructures within the material, and by balancing these stresses, it suppresses cracking, chipping, particle detachment, and crack propagation, thereby improving the lifespan of mold components and cutting tools and enhancing processing stability. It can be widely applied to mold components such as punches and dies, as well as cutting tools like drills and end mills. Additionally, it accommodates a variety of materials including carbide, high-speed steel, die steel, and cermet, and can be applied to coated products or those currently in use. This page introduces the basic concept of the DK Cryo Process. For detailed improvement cases and examples, please refer to "Applications and Case Studies." Feel free to contact us regarding processing feasibility or estimates.

The DK Cryo Process is utilized in various processing sites with the aim of improving the lifespan of mold components and cutting tools, as well as addressing chipping issues. 【Main Application Examples】 ■ Mold Components - Punches - Dies - Various mold components ■ Cutting Tools - Drills - End mills - Reamers - Taps - Other cutting tools 【Main Improvement Cases】 - Confirmed more than double the lifespan of cutting tools in cast iron machining (FC250) - Confirmed up to 7.5 times lifespan improvement in certain applications - Cases of chipping suppression in punches - Accumulated numerous improvement cases for mold components and tools - A collection of case studies for mold components and tools is available (we will send it by mail upon request) *Effects may vary depending on material, shape, and usage conditions. Please contact us for more details.
Detailed information
-
This process is a deep cooling treatment that cannot be fully explained by improvements in hardness, toughness, or refinement alone. By focusing on the stress state at the boundaries between heterogeneous regions within the material and balancing it, we aim to enhance resistance to breakage, wear, and improve processing stability. *This diagram is a conceptual illustration.*
