Company Profile
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
