[Dahyoung News] Dahyoung participates in the FIP-SPE@FCU Taiwan-Germany Project, innovating intelligent color monitoring capabilities for mass production of coating technology.
In October last year, Feng Chia University and the Fraunhofer Society—the world’s largest applied research organization—jointly established the FIP-SPE@FCU (Fraunhofer Innovation Platform for Surface Engineering for Optical and Electrical Systems at Feng Chia University), the first of its kind in Taiwan. Serving as a vital bridge for Taiwan-Germany technological exchange, industrial collaboration, and talent cultivation, the platform has now taken a significant step forward. This year, the platform’s proposal under the Ministry of Economic Affairs’ “A+ Industrial International Innovation R&D Program” has been officially approved, marking the formal launch of a Taiwan-Germany joint innovation research project. The German and Taiwanese teams — Fraunhofer IST, PLASUS GmbH, TRUMPF Hüttinger GmbH + Co. KG, NOVA POLYTEC COMPOSITES CO., and DAH YOUNG VACUUM EQUIPMENT CO., LTD — held the DE-TW Project Kick-off Meeting at Feng Chia University on October 29. To ensure the smooth implementation of this collaboration, the project kickoff meeting was held on October 29 at Feng Chia University. The German delegation, led by Dr.-Ing. Ralf Bandorf, included five senior executives from partner organizations, underscoring Germany’s strong commitment to this partnership. On the Taiwan side, representatives from corporate partners NOVA LEATHER ENTERPRISE CO., LTD —including President Kerry Huang (黃瑞凱總經理), Vice President Mr. Archy Huang (黃頎文副總經理), Executive Assistant Ms. Akilah Huang (黃怡婷特助), R&D Department Manager Mr. Lin (林伯學研發課長)—as well as DAH YOUNG VACUUM EQUIPMENT CO., LTD Technical Director Mr. Huang-Ming Zhang (張煌明技術總監) and R&D Manager Mr. Jack Chan (詹子厚研發經理), attended the meeting. The event was chaired by Prof. Ju-Liang He, Director of the FIP-SPE@FCU Center, with several Feng Chia University professors and research teams also participating to engage in in-depth discussions on technology development, R&D progress, and collaboration models. This project connects the FIP-SPE@FCU with Germany’s leading research and industrial partners, including PLASUS GmbH, and TRUMPF Hüttinger GmbH + Co. KG and Fraunhofer IST, while integrating the technical expertise of Taiwan’s NOVA Co., Ltd. and DAH YOUNG Vacuum Equipment Co., Ltd. The project aims to develop an intelligent color monitoring technology for mass-production coating processes, enabling real-time, active color control and feedback for long-term process stability. Its outcomes are expected to be applied to next-generation functional coatings and textile materials, aligning with the global shift toward green and sustainable manufacturing, while meeting market demands for color consistency, aesthetic quality, and enhanced international competitiveness. The project’s successful approval highlights the crucial role of the FIP-SPE@FCU in advancing international academia-industry collaboration—particularly in smart manufacturing, plasma technologies, and sustainable innovation. As the only Fraunhofer Innovation Platform in Taiwan, the platform serves as a strategic hub for fostering Taiwan-Germany technological exchange, industrial cooperation, and talent development. Through such initiatives, Feng Chia University continues to create opportunities for Taiwanese enterprises to connect with the global innovation ecosystem, driving industrial upgrading, technological advancement, and greater international impact for Taiwan’s high-end manufacturing sector. “A+ Industrial International Innovation R&D Program” has been officially approved, marking the formal launch of a DE-TW joint innovation research project.
