Picture show:

Our company was set up in a beautiful city Ningbo, which is closed to Ningbo seaport and airport. Weiwo is a specialized company that is engaged in producing auto spare parts, designing and manufacturing electromechanical & machinery spare parts, hydraulic motor and hydraulic valves with different series, agricultural pruning shears and related agricultural products.

We have a strong R&D team with full of creative spirit and develop many new products every year and have obtained many invention and utility model patents.

The products include mechanical shaft and spares, diesel engine parts, sealing element, agricuture tools and equipment, hydraulic motors and valves, powder metallurgy parts, du bushing and bearing, shock absorber parts, stamping parts, plastic and rubber parts, in addition we design and manufacture automatic machine such as shock piston banding machine and groove cutting machine.

As a professional enterprise of manufacturing and trade, we insists on pursuing better quality on and on. We control the quality strictly from raw material to finished parts. We have carried out an integrated production system which is based on quality focus. We refer to the rigorous four aspects ( material importing control→ production line control→ QC department control→ logistic department control ) and quality control system to make sure all the products are intact and perfect before delivery.

As a seller, our products are exported to the whole world and sold nationally for many years. More than one half parts are exported to USA, Germany, France, Canada, Brazil, India, Malaysia etc., have set up good relationships with the customers from home and abroad.
