ClassificationFaucet Guide 3632 0

The production process of faucets is maturing. At present, the price of faucets are sold in the market varies greatly. The same is a faucet. Why is there such a big difference in price? We will analyze the faucet from the perspective of the process.

1, Appearance

The outer surface of the faucet is generally chromed. The coating of the product has a specified process requirement and is subjected to a salt spray test for a certain period of time.

No corrosion occurs within the specified time. In sufficient light, it can be placed in the hand and observed directly. The surface of the tap should be black as a mirror, without any oxidation spots or charring marks. The surface of the tap should be black as a mirror, without any oxidation spots or charring marks. And it has no pores, no blistering, no leakage plating, color and luster uniformity. When you touch it with your hand, no burr feeling, sand grain feeling. Pressing the faucet surface with your fingers, fingerprints quickly spread, not easy to adhere to the scale. Some of the faucet surface is plated titanium, bronze (imitation gold), like gold electrophoresis paint.

2, Material

The main components of a faucet are usually cast from brass and are sanded, turned, acid dipped, pressure tested, polished, and plated. Some manufacturers use zinc alloy instead in order to reduce production costs. Handles, decorative nuts, and three-way bathtub faucet switch valves are basically made of brass, zinc alloy, and ABS engineering plastics. Wall coverings are made of brass, stainless steel, and plastic. Connecting nuts and eccentric joints and spouts are made of brass, and brass is recommended for the above components. The plating made of brass is of guaranteed quality and has a long corrosion resistance. The higher the purity of the brass, the better the plating quality and the less the surface coating is corroded. Zinc alloys have poor plating quality and poor corrosion resistance, while ABS plastics are the cheapest and have poor plating quality. It can be identified by weight estimation, minor surface scratches and surface plating quality. Brass is heavier and harder, zinc is lighter and softer, and plastic is the lightest and softest.

3, Functional aspects

Faucets are available in a variety of styles and functions. They are generally used for wash basins, kitchen sinks, bathtubs, showers, and bidets. According to the function, there are generally ordinary type, induction type, constant temperature type, etc..The induction faucet has the function of automatically sensing water, and the water is discharged from the outlet of the faucet, which is convenient and hygienic, more suitable for the bathroom in public places (high-grade).

4, Valve spool

The valve core is the heart of the faucet, and ceramic valve core is the best valve core. The better quality products all use ceramic spool, with strong wear resistance and good sealing performance. Generally can be used more than 300,000 ~ 500,000 times. The low-grade products are mostly copper, rubber and other seals, with a short life. But the price is lower.

5, Surface

The faucet should be glossy on the surface and free of burrs, pores and oxidation spots when touched by hand. The main body of a quality faucet is generally made of copper. The shaping, polishing, surface plating acid copper, and then plated nickel, chromium plating (three layers of plating); ordinary products are generally only plated nickel, chromium plating (two layers of plating). Ordinary products are plated with specific technical requirements and do not rust within a specified period of time through a neutral salt spray test. Therefore, high-quality faucet products with precise structure, uniform plating, smooth and delicate color, can be kept bright as new.

6, Handle

Turn the handle gently to see if it is light and flexible and if there is any blockage. Check the various parts of the faucet, especially the main components are tightly assembled, there can be no sense of looseness.
