About the Factory

We are a gear factory in Wutian, Ouhai District, Wenzhou, Zhejiang, China. For many years we have supplied precision plastic gears and gearboxes to China's domestic market — automotive actuators and smart home appliances are our home ground — and we now build the same products for overseas OEM customers.

Everything we sell is custom: there is no catalogue of stock parts. You send a drawing, we make the mold in our own tool room, mold the parts on all-electric machines, inspect them, and ship. plasticgearing.com is simply our factory, online under the name of what we make.
