Today we'd like to share a story about our chains technology!

2003: SUMAX plant has been researching vanadium infiltration technology.
2012: we conquered the challenge of vanadium infiltration polishing.
2013: our first-generation products were available for the aftermarket.
2015: supplied our second-generation products to OEM customers.
2018: we tackled the issue of uneven element distribution in the vanadium infiltration layer and introduced our third-generation technology.
2020: we solved the problem of wear and fracture caused by 10PPM pitting on the polished surface.

With the launch of our fourth-generation technology in 2020 and the resolution of micro pinholes in the vanadium infiltration layer in 2021, our hybrid-specific DH chains boast an average hardness of 2000hv and stable surface roughness.
