Copper Processing Industry Summit: New breakthroughs in the application of copper driven by multiple processes

In the era of vigorous development of material science and industrial manufacturing, copper plays an indispensable role in many fields with its excellent electrical conductivity, thermal conductivity, corrosion resistance and good

processing properties. An industry summit focusing on copper processing was held in the vibrant city. The summit attracted professionals, technical experts and representatives of upstream and downstream enterprises in the copper industry to gather together to witness the innovation achievements of copper processing technology and discuss the development trend of the industry.

Casting: Laying the foundation of copper molding

As the basic link of copper processing, casting is a key process to accurately transform liquid copper into various shapes of billets. In large casting areas, sand casting equipment runs in an orderly manner. Experienced craftsmen skillfully inject the blended copper solution into the elaborate sand mold. After cooling and solidifying, castings of various shapes appear before our eyes. These castings are widely used in the field of mechanical manufacturing, such as large copper valves, pipe fittings, etc., which provides a reliable guarantee for the stable operation of industrial pipeline system.

The wax mold is carefully made and then coated with multiple layers of refractory

material. After the wax mold is removed by high-temperature roasting, the cavity

is formed for pouring copper liquid. The castings produced by this process have high dimensional accuracy and excellent surface quality. In the field of aerospace, they are used to manufacture precision copper parts of engine fuel systems, such

as fuel injection nozzles, etc., to ensure the efficient operation of aviation engines.

Forging: To give the copper material excellent performance

Forging is an important process for plastic deformation of copper, through strong pressure to make copper deformation in the mold, so as to obtain the required shape and performance. Large forging press with huge force repeatedly forging copper billet, to promote its internal organization more dense, more refined grains.

In the manufacturing of electrical equipment, the forged copper alloy contacts not

only have higher electrical conductivity and arc resistance, can withstand the frequent impact of opening and closing current, but also significantly improve the mechanical strength, to ensure the safe and stable operation of electrical equipment. In the automobile industry, some parts forged with copper alloy, such as synchronizer tooth ring, etc., with their good wear resistance and mechanical properties, provide support for the efficient operation of the automobile transmission system.

Machining: The beauty of finely carved copper

Mechanical processing through turning, milling, drilling and other ways to accurately process copper. High-precision CNC machining equipment can be used to finely carve copper according to pre-set procedures. In the field of electronic equipment manufacturing, the dimensional precision of machined copper parts is extremely high, which can meet the needs of miniaturization and precision of electronic equipment. For example, the copper circuit board connector in the smart phone, after fine machining, not only has good contact performance to

ensure the stable transmission of signals, but also has a very high fit with electronic components, which provides a guarantee for the performance improvement of electronic products.

Surface treatment: enhance the value of copper charm

The surface treatment of copper is rich and varied, and nickel plating is one of the

most widely used. After nickel plating treatment, a hard and dense nickel layer is formed on the surface of copper, which not only greatly improves the corrosion resistance of copper, but also enhances its wear resistance and electrical conductivity. In the field of electronic components, the nickel-plated copper pin can effectively prevent oxidation and ensure the reliable transmission of electronic signals.

In addition, the chemical polishing process has also attracted much attention. It can form a uniform and smooth surface on the surface of copper and improve the appearance quality of copper. In the decoration industry, chemically polished copper decorations, such as copper sculptures, copper ornaments, etc., show a unique metallic luster and texture, satisfying people's pursuit of beauty and art.

Process coordination: help the copper industry to take off

The copper Processing Industry Summit made us deeply realize that casting,

forging, machining, surface treatment and other technologies do not exist in isolation, but are synergistic and closely coordinated. Casting provides the initial form of copper, forging optimizes its properties, machining achieves accurate

molding, and surface treatment endows it with protective and aesthetic properties. Together, they promote the wide application of copper in various fields.

From the extensive use of copper as a key component of transmission wires and electrical equipment in the power industry, to the important support of copper in key systems in the aerospace field, to the innovative application of copper in electronics, automotive and other industries, the continuous progress of copper processing technology has greatly improved the performance and quality of copper. These processes not only show the exquisite skills of copper processing, but also reflect the important position of copper in modern industry and broad prospects for development.

In this journey of exploration of copper processing, let us continue to innovate, and jointly look forward to the copper processing industry to create more brilliance in the future, and contribute more copper wisdom and strength to the global industrial development.
