Heat Treatment / Coating |
| 2003 |
Proud of advanced technology, an expert in metal surface modification, "Heat Treatment / Coating". |
| 2003 |
Since the days of the Chubu Thermal Refining Laboratory, the predecessor of JTEKT Coating, which specialized in research and development, heat treatment has been promoted. |
| 2003 |
At the time of establishment, quenching and tempering called heat treatment was mainstream, but under the founding spirit of "dedicating ourselves to research and creation, always staying ahead of the times," development efforts were made. Currently, it enables diverse heat treatment processes such as carburizing, high-frequency quenching, and gas nitriding with over 2000 model types and 600 conditions. |
| 2003 |
As an expert in heat treatment, aiming for low distortion and a beautiful finish, we develop composite processes utilizing various heat treatment technologies and mass production techniques to achieve high quality and low cost surface modification. |
| 2003 |
Furthermore, we quickly started DLC (Diamond-Like Carbon) coating on automotive parts and succeeded in mass production of automotive parts. Using thick intermediate layers for high adhesion films and microwave-based inner diameter film formation technology, we contribute to solving customer issues. |
| 2003 |
We also realize integrated heat treatment processing for automotive parts and actively work on creating value that satisfies customer expectations. |
