For overseas buyers managing multiple suppliers, coordinating machining and surface treatment across vendors often causes delays and quality gaps. Zhejiang Shangshi Precision Hardware Mfg. Co., Ltd. addresses this by offering CNC-machined parts together with surface treatment under one roof, so components arrive ready for assembly.
The company supports a range of finishes matched to the base material: anodizing (clear and black) for aluminum parts, zinc plating and nickel plating for steel components, passivation for stainless steel, and powder coating for visible brackets and housings. Salt-spray performance is verified in the in-house test lab, with test hours set according to each customer's specification.
Each shipment includes material certificates, dimensional reports from CMM inspection, and salt-spray test records where required. This single-source approach shortens lead times and gives customers one contact point for quality issues across machining and finishing.
