Founded in 1991, Taizhou Tengkai Machinery Co., Ltd.(TIMTECH) has spent over three decades specializing in the R&D, precision manufacturing, and innovation of critical copper components for refrigeration and air conditioning systems.
From a single nut or fitting to complex valve bodies and distributors—every part we make serves as a foundational element for reliable HVAC&R performance. To meet this responsibility, we've built a fully digitalized production line powered by more than 400 CNC lathes, enabling our transformation from traditional "manufacturing" to intelligent "smart manufacturing." Today, our daily output consistently exceeds 300,000 precision copper components—a milestone that reflects not just scale, but a fundamental leap in production consistency, dimensional accuracy, and on-time delivery reliability.
Quality is embedded in our DNA. We operate under an integrated management system certified to ISO 9001 (Quality), ISO 14001 (Environmental), and ISO 45001 (Occupational Health & Safety), with CQC product certification as our technical benchmark. This comprehensive quality ecosystem ensures every component is produced in a controlled environment, through fully traceable processes, and with a commitment to sustainable responsibility—giving customers peace of mind that goes beyond expectations.
As a trusted long-term partner to industry leaders such as Midea, Xiaomi, and Changhong, we maintain service hubs near all major air conditioning manufacturing clusters across China. This deep integration into our customers' ecosystems allows us to respond rapidly, innovate proactively, and act as a truly agile and dependable extension of their supply chain—co-building reliability into every refrigeration system we help bring to life.
