A factory built on precision, transparency and long-term partnership.
Nanjing Coolanna Technology Co., Ltd. was founded in Nanjing, Jiangsu Province — one of China's most important manufacturing and logistics hubs, located just 300 km from the Port of Shanghai.
We started as a small spinning workshop serving domestic lighting brands. Today, our 12,000 m² facility combines CNC metal spinning lines, 3/4/5-axis machining centers and a full metrology lab, exporting to more than 30 countries across Europe, North America, Central Asia, the Middle East, Japan and Korea.
What hasn't changed is our founding principle: treat every client's project as if it were our own product. That means honest engineering advice, prices we can stand behind, and parts that arrive exactly as drawn.


Our quality management system is certified to ISO 9001:2015 and designed around the expectations of European and Japanese OEM buyers.
If a drawing isn't manufacturable or our price isn't competitive, we tell you straight away — no hidden surprises.
98.6% on-time shipment record over the past three years, tracked order by order.
Dedicated project manager, English communication, and proactive cost-reduction suggestions.
New equipment investment every year — latest additions include a 5-axis machining center and CNC spinning line.
We welcome factory audits and live video tours any time. See our workshop before you place your first order.
