On October 31, 2025, TONA was honored to accompany Phoenix Contact in the Grand Opening Ceremony of the Group’s 51st factory at Amata Industrial Park, Dong Nai, Vietnam—a significant milestone in the Group’s expansion journey across Southeast Asia.
Over a Century of Technological Innovation from Germany
Founded in 1923, Phoenix Contact is one of Germany’s leading technology corporations, pioneering in electrical connection, automation, and sustainable energy systems.
For more than a century, the Group has continually advanced technology that drives global energy transition and fosters a greener future.
The establishment of its 51st factory in Vietnam not only reflects Phoenix Contact’s strategic vision to expand its global manufacturing network but also highlights Vietnam’s growing role in the high-tech industrial supply chain of the region.


TONA – Design & Build Contractor of Excellence
As the entrusted Design & Build Contractor, TONA successfully delivered the project under strict safety, quality, and technical requirements.
Within just 171 days of construction, the TONA team brought the project to completion on schedule, achieving international standards across all categories—from structural works and MEP systems to technical infrastructure and modern production spaces.
This achievement once again demonstrates TONA’s expertise in factory renovation and construction, as well as the close coordination and trust among all project stakeholders throughout the process.
TONA extends our sincere gratitude and appreciation to Phoenix Contact’s Leadership Team, the Project Team in Vietnam, and all partners for their continuous support, timely guidance, and trust, which enabled us to accomplish the project successfully under challenging conditions.



The inauguration of Phoenix Contact Vietnam Factory marks the beginning of a long-term and sustainable partnership between our two companies.
Sharing common values of quality, innovation, and sustainability, TONA and Phoenix Contact are committed to deepening collaboration and contributing to the development of Vietnam’s high-tech manufacturing sector and the broader Southeast Asian region.
