About AOFENG Thailand
Built in Thailand.
Trusted worldwide.
A precision spring manufacturer in Rayong, Thailand — part of the AOFENG Group and purpose-built to give global OEMs a flexible, country-of-origin-diversified supply base.
A Thailand manufacturing base, built for global OEMs
AOFENG SPRING (THAILAND) CO., LTD. was established in 2017 in Rayong province, in Thailand’s Eastern Economic Corridor. The plant combines the AOFENG Group’s spring-making experience with a Thailand-origin production base — helping OEMs diversify supply geography without compromising on quality.
Our Rayong facility brings forming, heat treatment, surface finishing, grinding and quality control under one roof. Production began in October 2019 with Phase 1, and Phase 2 started in May 2021. In November 2021 we purchased an additional 23.6 rai (approximately 37,760 sqm) of land for future development — a long-term commitment to Thailand and to the customers we serve from here.
- Thailand-origin manufacturing, registered locally since 2017
- Vertically integrated: forming, heat treatment, finishing and inspection
- Part of the AOFENG Group, founded in Foshan, China in 2005
