Cooperation Background:

As a leading global construction machinery brand, Sany undertakes numerous engineering projects all over the world. Its hydraulic cylinders, excavators and concrete machinery operate under heavy-load, dusty and high-pressure working conditions, requiring reliable, wear-resistant and cost-effective customized sealing parts. The existing supply chain cannot fully meet customized bulk demand, so Sany selects Guohao Seals to provide professional OEM & ODM sealing solutions for construction machinery.
