By incorporating elements essential to next-generation mobility into our R&D themes, we are pursuing research that goes beyond the development of conventional components to cover a broader range of technological domains.
Analysis Technology (CAE Simulation)
G-TEKT recognized early on the need to internalize not only manufacturing simulations but also performance simulation technologies for the body-in-white (BIW; the unpainted, joined body shell before paint, trim, and final assembly), through its collaborative work with automotive OEM customers. Over time, we have accumulated extensive expertise in this field. By leveraging material data obtained through manufacturing, we are able to carry out highly accurate collision simulations.
With our deep understanding of the functions required of vehicle bodies, we can propose optimal component configurations and designs.
Performance Evaluation Technology
We are enhancing our evaluation technologies to verify that our designs meet the required performance standards for the next-generation vehicles we envision. In addition to testing the performance of independently developed components, we also conduct verification tests to ensure superior quality and performance.
The images below show an example of a crush test recorded on video and analyzed using digital image correlation (DIC). This method enables us to measure not only load and deformation but also the distribution and magnitude of strain. By capturing and analyzing more information from a single test, we are able to advance R&D more efficiently.

Joining Technology
We are conducting R&D to pursue optimal joining technologies that address the ongoing evolution of automotive body manufacturing. With the advancement of materials and the increasing diversity of vehicle body designs, the combinations of materials to be joined have grown more complex. To address this, we identify the most effective joining methods and conditions, achieving both high-quality and high-efficiency joining.

Forming Technology
To meet diverse needs and reduce environmental impact, we are advancing the sheet-metal forming technologies accumulated over the years to explore new approaches to vehicle manufacturing. We are developing technologies that enable the forming of difficult-to-process materials and complex shapes, thereby producing lightweight, low-cost components that enhance vehicle body performance, including collision safety and ride comfort.
