About Us
A decade in the heart of China's power-tool belt.
Nantong Kunlong Electromechanical Co., Ltd. is the manufacturer behind WOERDI®. Headquartered in Lüsi, Nantong — Jiangsu's recognized cluster for cordless tooling — we have spent ten years turning lithium energy into dependable jobsite power.

Our Story
From a single motor line to a global brand.
Kunlong began with a focused conviction: that the future of professional tools is cordless, and that quality begins with the motor. We started by mastering brushless motor manufacturing, then progressively integrated lithium battery PACK assembly, precision injection molding, and full product assembly.
Today, WOERDI® is our face to the world — a registered brand recognized by wholesalers and trade buyers across more than five continents. We do not chase trends; we ship tools that hold up to a working week.
Whether you are launching your first private label or scaling an existing range, we treat your roadmap with the same rigor we apply to our own.
Mission
Engineer professional lithium tools that combine premium specifications with OEM economics — and back them with a partnership that lasts.
Vision
To be the most trusted manufacturing partner for global power-tool brands serving construction, garden, automotive and renovation.
Values
Craftsmanship, accountability, openness. The phoenix on our logo represents renewal — we improve every batch, every cycle.
By the Numbers
The work speaks for itself.
