We, the Dexerials Group, under our corporate vision of “Value Matters Unprecedented innovation, unprecedented value” contribute to our customer’s product value, through explore technologies, and provide high quality products and services.

The foundation of quality maintenance and improvement within the Dexerials Group is our quality management system (QMS), which conforms to international standards. All of our manufacturing sites are certified under ISO 9001, and certain products for the automotive industry undergo rigorous quality assurance based on IATF 16949, the sector-specific standard for the automotive industry, as well as the VDA standards issued by the German Association of the Automotive Industry.
Furthermore, to ensure full compliance with regulatory requirements and customer needs, we have established a QMS promotion framework led by top management. Cross-organizational collaboration is essential for product realization and the achievement of quality targets. To facilitate this, we operate through a process-based responsibility structure, defining units that require coordination as “business processes.”
In addition, we monitor these activities through regular internal audits. During the audits, we review work procedures based on applicable laws and internal rules, verify the appropriateness of quality specifications for each process, identify and address issues, and report the results to top management. Through this PDCA cycle, we ensure the effectiveness of our QMS.

All the manufacturing sites of the Dexerials Group have obtained ISO 9001 certification for quality management systems that provide the basis for promotion of the quality philosophy and the basic policy and for business activities, such as design, development, manufacturing, and quality assurance. Regarding products for automotive applications, we have obtained certification for IATF 16949, a standard for the automotive industry for the maintenance of the high quality and reliability required for automobile parts and we also comply with the VDA standard (quality standard of the German Association of the Automotive Industry).

We test our products for compliance with a range of product safety standards and acquire the relevant certifications to ensure that products are safe for customers to use with complete confidence. Regarding the essential international standard, the UL standard (safety standards established by UL LLC, a company that enacts safety standards and conducts tests and certification), in particular, not only did we respond to the demand from customers for certification registration but also from the viewpoint of ensuring product safety, we have proactively received certification for various products in the Dexerials Group as we continue to supply safe products at the parts level.
As many of our products are in a liquid form, in order to accurately communicate product safety information to customers, Dexerials has introduced a dedicated system for preparation of safety data sheets (SDSs) and provides SDSs compliant with laws and regulations in Japan and abroad.

The Dexerials Group is also promoting DX in quality control, believing the advanced data utilization (data driven) with cutting-edge technologies represented by AI, IoT, data science, etc., will lead to its further growth. We are working on increasing our competitiveness by innovatively improving quality based on the abundant data and knowledge which have been accumulated so far.
The Dexerials Group produces a lot of roll-shaped film products, which is its main product. As they are continuously produced over a long period of time, it has been a critical issue for quality control to prevent failures from occurring in series due to unexpected causes. In order to solve this problem, we are promoting efforts to establish a more sophisticated quality control system that can predict anomalies in advance and controls processes, and achieve a smart factory.
At the Headquarters and Tochigi Technology Center, we incorporate automated optical inspection equipment and auto measuring device using our proprietary image processing in Anti-reflection Film (ARF). We have developed and built a system to classify defect images in real time and with high accuracy by utilizing AI’s deep learning capabilities for the vast amount of data obtained from the equipment, and are moving forward with the development of smart factories.
These efforts have prevented the continuous occurrence of defects, reducing the defective product rate and significantly enhancing profitability. Moreover, we have further improved quality through the analysis of tens of thousands of pieces of data obtained during the production process. Furthermore, since fiscal 2022, we have been building a quality control system for preventative measures by linking data with SCADA* systems and other systems to improve the accuracy of anomaly detection and prediction. These smart factory developments are also being promoted at other sites.

Through communication with customers, the Dexerials Group shares customer needs and technology issues. We offer technology-based support and solutions, working toward the creation of products that respond to customers’ confidence in us and deliver customer satisfaction.
In the event of quality issues that could impact stakeholders, including where there is the threat of serious quality issues and product incidents occurring, a system is in place whereby the relevant corporate department promptly reports the situation to top management so that appropriate response measures can be taken.
Regarding returns and recoveries due to complaints made by customers, an analysis is performed by specialist technical staff with advanced analytical skills, and the analytical reports and follow-up measures are promptly implemented. For defects whose causes are difficult for customers to identify, we provide technical support for the investigation of the causes using our sophisticated analytical capabilities.

Developing quality personnel is essential for maintaining high quality standards. In accordance with the Dexerials Group’s basic human resource development policy, we focus on cultivating personnel with specialized expertise in quality management. Based on our Quality management training road map, we have established a curriculum that combines understanding of ISO 9001 and IATF 16949 standards, mastery of QC (quality control) methods and statistical techniques, and practical exercises, thereby continuously developing the next generation of specialists.
Training is provided through multiple formats—including e-learning, online sessions, and classroom lectures—to enhance learning opportunities according to the training environment.
In addition, to prevent quality misconduct, which has become a serious social issue, we conduct annual compliance training for all employees specifically focused on quality. The training covers case studies from other companies as well as the mechanisms behind quality misconduct, helping to raise awareness across the organization.
