What is the production process of the faucet?

The production process of the faucet:

Copper ingot→dissolving→casting (low-grade casting with sand casting, high-quality faucet with gravity casting)→cleaning after casting→casting inspection→machining→tolerance inspection→leak test→grinding→surface inspection→plating→plating inspection→assembly→ Water test and leak test → finished product inspection → packaging → delivery.

Casting: low-end casting is made with sand casting, high-quality faucets are made with gravity casting, and the newer technology is die-casting. One-time pressure grinding is similar to zinc alloy die casting.

Quality control: The quality in the production process before the finished product is controlled by the quality control, and the quality assurance part conducts random inspections from the finished product to the packaging, mainly to check the packaging and placement of the product.
