Production Quality Standards

Our engineering team provides comprehensive support throughout the moulding, die-casting, machining, and finishing processes. We strictly monitor every production step to ensure a high 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 layers: Cu ≥ 15μm, Ni ≥ 10μm, Cr ≥ 0.15μm. Products pass neutral 240-hour or acidic 48-hour salt spray tests. Custom salt spray testing in excess of 480 hours is available. We never use return material directly for die-casting production.
