Ready to customize your handlebar stems? Send us your technical drawings, 3D files, or samples. Our engineering team will review your needs and provide a competitive solution.
With the whole process of moulding, die-casting, machining, polishing, plating/powder coating/painting, inspection, assembly and shipment, we can strictly control every step of handle production to ensure quality and improve product qualification rate.
We provide OEM/ODM services for many famous international brands in Europe and America — for example, TOTO, Dornbracht, Roca, KLUDI.
Plating Standard We strictly control the thickness of plating layer of copper, nickel and chrome: Cu ≥ 15μm, Ni ≥ 10μm, Cr ≥ 0.15μm. Products can pass neutral 240 hours or acidic 48 hours salt spray test. We also customize handles for salt spray testing in excess of neutral 480 hours. We promise never to use return material directly for die-casting production.
