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.
Actually we provide OEM/ODM services for many famous international brands in Europe and America. For example, TOTO, Dornbracht, Roca, KLUDI.
We strictly control the thickness of plating layer of copper, nickel and chrome, usually our plating thickness is: Cu ≥ 15um, Ni ≥ 10um, Cr ≥ 0.15um, and can pass neutral 240 hours or acidic 48 hours salt spray test. We also customize your handles for salt spray testing in excess of neutral 480 hours. And we promise never to use the return material directly for die-casting production.
Sincerely welcome you to call us and visit our factory!
