For global brands and distributors, the "Origin" of their products is just the beginning. The real value lies in the manufacturing process—the journey from a raw concept to a high-quality product ready for the international market. Understanding this process is vital for B2B buyers who need to ensure reliability, quality consistency, and timely delivery.
At Zhejiang Xindong Sanitary Ware Co., Ltd. (XINDONG), we have perfected this journey over the last 25 years. Here is a step-by-step look at how we transform a client’s inquiry into a finished product ready for global export.
The process begins long before the first piece of brass is melted. It starts with a conversation.
Once a client submits an inquiry, our engineering team reviews the technical drawings or physical samples. We discuss material requirements, finish types, and certification needs (such as CE, WRAS, or WaterMark). If it’s a new design, we use CAD software to create blueprints and, if necessary, 3D-printed prototypes to verify ergonomics and aesthetics before moving to tooling.
Once the design is finalized, we create high-precision molds. At XINDONG, we invest heavily in durable, high-accuracy molds to ensure that every casting is consistent, reducing waste and ensuring a perfect fit for internal components like cartridges and aerators.
This is where the physical product takes shape.
We primarily use gravity casting for our faucet bodies. This process involves pouring molten high-quality brass into the molds. Gravity casting is superior to sand casting because it creates a denser, more uniform structure with fewer air bubbles, which is critical for preventing leaks under high pressure.
The "raw" castings then move to our CNC (Computer Numerical Control) machining center. Here, automated machines drill the internal waterways and thread the connections with sub-millimeter precision. This ensures that every XINDONG product is 100% compatible with international plumbing standards.
The aesthetics and durability of the product are determined in this stage.
Every piece is hand-polished or robot-polished to remove any surface imperfections. After polishing, the products undergo surface treatment—whether it's traditional multi-layer electroplating (Chrome) or advanced Physical Vapor Deposition (PVD) for premium finishes like Brushed Gold or Matte Black.
In our assembly line, high-grade ceramic cartridges, aerators, and O-rings are installed. Every single faucet and valve is then subjected to a 100% air and water pressure test. We do not do "batch sampling" for leaks; every unit must pass the test before it can be packaged.
The final step is ensuring the product reaches the client in perfect condition.
Our QC team performs a final visual inspection under high-intensity lighting to check for finish defects. Products are then packed in custom-branded, protective packaging designed to withstand the rigors of international sea freight.
XINDONG’s logistics team manages the documentation, customs clearance, and container loading. Located in the heart of China’s sanitary ware manufacturing hub in Zhejiang, we have easy access to major ports, ensuring efficient shipping to our partners in Europe, the Americas, and Southeast Asia.
For standard products, our lead time is usually 30-45 days. For new designs requiring custom mold creation, the initial phase may add 2-3 weeks to the timeline.
We source our raw brass from certified suppliers and perform spectral analysis on every batch of incoming material. We can provide material test reports to ensure compliance with specific regional regulations like California's AB1953 or Europe's drinking water standards.
Absolutely. We encourage our long-term partners to visit our facility in Xuanmen Industrial Zone. Seeing our CNC machines, gravity casting stations, and testing labs firsthand provides our clients with the confidence they need in our manufacturing capabilities.
The OEM manufacturing process is a complex symphony of engineering, craftsmanship, and logistics. By maintaining total control over every stage—from the initial inquiry to the final export—XINDONG ensures that our global partners receive products that are not only beautiful but engineered to last.
When you partner with XINDONG, you aren't just buying hardware; you are leveraging 25 years of manufacturing excellence.
