High surface pressure resistance technology "KHD treatment"

Vacuum hardening that improves the durability of molds and tools by more than three times! Introduction of our uniquely developed technology.

We would like to introduce KHD processing, a unique development technology by Kuniyu Thermal Engineering. From the perspectives of weight reduction for improved fuel efficiency and enhanced safety, the introduction of high-strength steel materials is increasing. However, these materials are difficult to process, leading to significant wear on molds and tools, which necessitates improvements in strength and durability. Our development technology applies vacuum carburizing treatment to these tools, achieving excellent surface modification treatment for high surface pressure wear resistance, thereby extending the "lifespan" of molds and tools. This results in cost reduction through decreased frequency of mold replacements and improved productivity, while also addressing the anticipated "further adaptation to higher strength steel materials" in the future. [Key Points] ■ Hard coating with high resistance to high surface pressure → Generates a hard coating on the surface of the component with a hardness of approximately Hv3,000 (Hv = Vickers hardness) - Result: Wear resistance to high surface pressure is enhanced by more than twice ■ High adhesion "non-peeling coating" → Creates a "substrate gradient reinforcement layer" with a gradient hardness distribution into the base material - Result: Achieves three times the adhesion of conventional coatings with a "non-peeling coating" *For more details, please refer to the PDF document or feel free to contact us.
