Faucet manufacturing process: From brass bars into faucets



At Spark Faucet Factory, we take immense pride in our faucet manufacturing process, which blends innovation, precision, and expertise to create faucets of unparalleled quality and design. Our commitment to excellence extends from the selection of top-notch materials to the incorporation of advanced techniques, resulting in faucets that stand the test of time.

In this post, I’ll take you through the fascinating journey of how a SPARK faucet is made, from initial design to the final quality test. This process ensures that every faucet we produce meets the highest standards of quality and design, reflecting our commitment to excellence.

What Does Faucet Design and Mold Making Involve?

The journey of a SPARK faucet begins with design and mold making. Our design team of skilled designers and engineers collaborates to create original and aesthetically pleasing faucet designs and transform these designs into precise molds. These molds are crucial for shaping the faucet’s body in later stages.

How Important is Solid Core Making in Faucet Manufacturing?

Solid core making is a vital step in ensuring the structural integrity of our faucets. This process involves creating a solid, durable core that forms the internal structure of the faucet. It’s a meticulous process that requires precision and attention to detail, ensuring that each faucet is robust and long-lasting.

Why Do We Choose Premium Raw Materials?

The most important ingredient in faucet production is brass, from which the faucet body is made by means of casting. Spark faucets are used to make the faucet is generally H59 or lead-free copper. In addition to strong corrosion resistance, low melting point (easy to cast), and sterilization, brass is commonly used as a raw material in the market. Of course, there are faucets made of other materials, such as stainless steel and zinc alloy. Stainless steel is somewhat lead-free, but has a high melting point and is not easy to form. The shape of the cast faucet is relatively simple. The biggest feature of zinc alloy is its low price, but the cast faucet is harmful to health.

What is the Gravity Casting Process in Faucet Manufacturing?

Gravity casting is where the magic happens. In this process, molten brass is poured into the molds we created earlier. This method allows for precise shaping of the faucet body, ensuring a flawless and uniform finish. The gravity casting process is a testament to our commitment to producing high-quality faucets.

How Does CNC Machining Enhance Faucet Quality?

After casting, the faucet bodies are refined using CNC machines. This technology enables us to achieve unparalleled precision in the detailing of each faucet. CNC machining is crucial for ensuring that every curve and edge is perfect, aligning with our original designs.

What Goes into the Surface Treatment of Faucets?

Surface treatment is not just about aesthetics; it’s about durability. Our faucets undergo various treatments, including polishing, plating, and coating, to ensure they are resistant to tarnish and corrosion. This step is crucial in maintaining the faucet’s appearance and functionality over time.


The surface treatment process mainly includes PVD (Physical Vapor Deposition), ORB (Oil Rubber Bronze), plating Plating, etc. The most widely used faucet is electroplating chromium. Electroplating can enhance the corrosion resistance of the faucet, increase the hardness, prevent wear and increase the appearance of the surface.

How is Assembly Integral to Faucet Manufacturing?

Assembly is where all the components come together. Our skilled workers meticulously assemble each part, ensuring that every faucet functions flawlessly. This stage is critical in ensuring the faucet’s durability and reliability.

Why is Quality Testing Essential in Faucet Production?

The final and most crucial step is quality testing. Every SPARK faucet undergoes rigorous testing for leaks, durability, and functionality. This ensures that our customers receive a product that not only looks great but also performs exceptionally.

After the casting of the faucet is electroplated and passed the inspection, it can enter the assembly process. Assembly is the process of connecting processed faucet parts in a certain order and technology to become a complete faucet product and reliably realize the function of product design. Assembly is at the final stage necessary for the manufacture of the product, and the quality of the product (from product design, part manufacturing to product assembly) is finally guaranteed and tested by assembly.

Spray Test

The quality of the plating surface treatment can be judged by the 24-hour acetate spray test, and the coating thickness gauge can be used to identify the thickness of each metal coating. Generally speaking, the thickness of the coating is up to standard and the salt spray test can pass. Electroplating is a process of pollution and energy consumption. The general faucet production factory must hand the faucet to a professional electroplating factory for electroplating, which increases the production time and the difficulty of control.



The journey of creating a SPARK faucet is a blend of art and science. From design to quality testing, each step is carried out with precision and care, reflecting our commitment to excellence. We take pride in every faucet we produce, knowing that it meets the highest standards of quality and design.
