    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:

    Cu ≥ 15μm  |  Ni ≥ 10μm  |  Cr ≥ 0.15μm

    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!

    Frequently Asked Questions
    QWhat zinc alloy materials do you use for die-casting?
    We primarily use Zamak 3 (ZnAl4Cu0.1) and Zamak 5 (ZnAl4Cu1) in compliance with ASTM B86 standards. These materials offer an excellent balance of strength, dimensional stability, and surface finish quality, making them ideal for precision hardware components.
    QWhat surface finishing options are available?
    We offer a wide range of surface treatments including polishing, electroplating (nickel, chrome, zinc), powder coating, spray painting, and PVD coating. Custom colors and finishes such as chrome, brushed nickel, antique bronze, and matte black are all available upon request.
    QDo you support OEM and ODM orders?
    Yes, we fully support both OEM and ODM services. We provide CAD/3D modeling assistance, DFM analysis, rapid prototyping within 5–7 working days, high-precision mold manufacturing, and custom logo and packaging options. We have extensive experience serving internationally renowned brands in Europe and America.
    QWhat is your salt spray test performance standard?
    Our standard plating thickness ensures a minimum of 240 hours neutral salt spray test or 48 hours acidic salt spray test performance. For customers requiring higher corrosion resistance, we can customize products to exceed 480 hours of neutral salt spray testing. Our plating specs: Cu ≥ 15μm, Ni ≥ 10μm, Cr ≥ 0.15μm.
    QWhat is the typical lead time for samples and bulk production?
    Prototypes and samples are typically delivered within 5–7 working days. Bulk production lead times vary depending on order complexity and quantity, but we work closely with customers to meet project deadlines. Please contact us for a specific timeline based on your requirements.
    QWhat quality control measures do you have in place?
    We are ISO 9001:2015 certified and implement strict quality control throughout the entire production process — from mold making, die-casting, machining, polishing, plating, and final inspection to shipment. Our QC includes 100% dimensional inspection, SPC process control, and full material certification. We never use recycled return material for die-casting production.
