Hangzhou Ocean Industry Co., Ltd. is a professional manufacturer. Since 2005, the majority of our products have been exported to Europe. Most of our OEM clients provide technical drawings, and
we manufacture products strictly in accordance with their requirements. Samples are also acceptable if you do not have drawings available.
The Ocean Group’s industrial layout dates back to 2000, when our first gearbox plant was founded. The second gear production factory opened in 2001, followed by our chain factory in 2003. To
cut overall export costs, we founded Hangzhou Ocean Industry Co., Ltd. in 2005 to unify all group export businesses. Our drive shaft factory was put into operation in 2008, and we have
expanded with additional workshops later, including a production base for conveyor line components.
We specialize in customized OEM product development as a full-service manufacturer. We have gained long-term trust from global partners thanks to our integrity, deep insight into client
demands, and strict accountability for every order. With decades of experience cooperating with overseas buyers, our transmission products enjoy wide popularity across European markets.
Equipped with state-of-the-art production machinery, we maintain a team of skilled engineers and comprehensive after-sales support, continuously strengthening our brand credibility worldwide.
