The manufacturing process of air conditioning copper pipes goes through several steps: First, manufacturers purchase high-quality copper materials, which are carefully screened and tested to ensure that they have excellent thermal conductivity and corrosion resistance. Next, the copper is machined to the desired diameter and wall thickness, usually using a copper tube rolling or drawing process. In the process of rolling or drawing, cold drawing, pickling and annealing are also needed to improve the mechanical properties and surface finish of copper pipes. Finally, after cleaning, packaging and quality inspection steps, air conditioning copper pipe can enter the market

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 ‌

Horizontal continuous casting copper strip is mainly used in the production of electrical components, lamp caps, battery caps, buttons, seals, connectors, etc., mainly used in electrical conductivity, thermal conductivity, corrosion resistance equipment. ‌ For example, electrical components, switches, washers, gaskets, electric vacuum devices, radiators, conductive base materials, automotive water tanks, heat sinks, cylinder sheets and other parts ‌1. Horizontal continuous casting copper strip has been widely used in electronic, electrical, light industry, instrumentation and other fields. Especially in the rapid development of the electronic information industry, the consumption of copper and copper alloy sheet and strip has increased year by year, becoming high-tech and high value-added products. The main application areas include the manufacture of connectors for electrical connectors, integrated circuit lead frames, automotive water tank heating tubes, automotive terminals, coaxial cables, dry transformers and electronic switches ‌2. The production process of horizontal continuous casting copper strip includes melting, casting and other links, which has the characteristics of high efficiency and energy saving. Molten steel produced by blast furnace smelting or other methods is poured into the copper ladle equipped with protective liquid, and then transferred to the position of continuous casting machine, molten steel flows from the copper ladle to the mold, the molten steel is gradually solidified in the mold through the cooler, and finally cut into the casting billet of appropriate length by the shear device for subsequent processing or directly as semi-finished product ‌
