Let's Elevate Your Spaces with Durability Meets Design!
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.
We strictly control the thickness of plating layer of copper, nickel and chrome. Our standard plating thickness is: Cu ≥ 15μm, Ni ≥ 10μm, Cr ≥ 0.15μm, and 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.
Sincerely welcome you to call us and visit our factory!
