Production Process
The production process of the faucet:
Copper ingot→dissolution→casting (low-grade casting with sand casting, high-quality faucet with gravity casting)→cleaning after casting→casting inspection→machining→tolerance inspection→testing leak→grinding→surface inspection→electroplating→electroplating inspection→assembly→ Test water leak test → finished product inspection → packaging → factory.
Casting: low-grade casting with sand casting, high-quality faucet with gravity casting, the new technology is die-casting, and the primary pressure-molding process is similar to the zinc alloy die-casting process.
Quality control: The quality of the production process before the finished product is controlled by quality control. The finished product to the packaging is sampled by the quality assurance part, mainly to check the packaging and placement of the product.
Purchase method
Look at brightness
The surface chrome plating process of a good faucet is very particular, and it usually takes a few steps to complete. To distinguish the quality of the faucet depends on its brightness, the smoother the surface, the brighter the better the quality.
Turn handle
When the faucet is turned, there is no excessive gap between the faucet and the switch, and it is easy to open and not slip. Inferior faucets not only have large gaps, but also have a large sense of resistance.
Listen to the sound
The material of the faucet is the most difficult to distinguish. The good faucet is cast in one piece, and the sound is dull. If the sound is very brittle, it must be made of low-grade stainless steel. It contains more iron and the quality is worse than a grade.
Identification mark
If you really can't tell, you can choose a regular brand. Generally, regular products have the brand logo of the manufacturer, while some informal products or some quality products are often only pasted with some paper labels, or even without any marks. Be sure to pay attention when purchasing.
