The main production process of faucet copper ingot casting line includes the following steps ‌ : Dissolving of copper ingot ‌ : First of all, the copper ingot is put into the melting furnace, and the impurities such as oxygen and sulfur in the copper liquid are removed through high temperature melting to ensure the purity and quality ‌. Casting ‌ : According to the grade of the product, the casting process is also different. Low-grade products are usually cast with sand, while high-quality faucets are gravity cast. The latest technology also includes die casting, which is a single die grinding process similar to the modern zinc alloy die casting process ‌. Cleaning and inspection after casting ‌ : After the casting is completed, the casting needs to be cleaned to remove the sand core and excess metal on the surface. The casting is then inspected to ensure that there are no defects ‌. ‌ machining and tolerance inspection ‌ : the casting is machined, the size and shape are adjusted, and the tolerance inspection is carried out to ensure that the product meets the design requirements ‌. Grinding and surface treatment ‌ : The product is ground to give it a smooth surface. This is followed by surface treatment, such as electroplating, to improve the corrosion resistance and appearance quality of the product ‌. Assembly and finished product inspection ‌ : The ground and electroplated parts are assembled for water testing and pressure testing to ensure the tightness and durability of the product. Finally, the finished products are inspected and packed, ready for delivery ‌. Quality control ‌ : Quality control is very important in the whole production process. The quality in the production process is the responsibility of the quality control department, while the final product to the packaging stage is carried out by the quality assurance department, mainly to check whether the packaging and placement of the products meet the requirements ‌
