Explore the innovation password of copper processing frontier technology
In the era of rapid development of material processing technology, copper with its excellent electrical conductivity, thermal conductivity and excellent processing performance, occupies a pivotal position in the industrial field. Recently, an international copper Processing Summit, which gathers the elites of the global copper processing field, was held in Shenzhen. This event not only comprehensively demonstrated the cutting-edge technology and innovation achievements of copper processing, but also a feast of knowledge to deeply explore the mysteries of copper processing technology. From casting to forging, from stamping to surface treatment, each process contains infinite innovation vitality and technical charm.
Melting casting: gives initial life to copper
As the starting link of copper processing, melting casting is a key step to transform copper raw materials into ingots with specific shapes and properties. In large furnaces, copper raw materials gradually melt into hot copper liquid at high temperature, and then through precision casting equipment, it is accurately cast
into various molds. In this process, the precise control of temperature, composition and casting speed is essential.
The advanced melting casting technology can effectively reduce the defects such as pores and inclusions in the ingot and improve the purity and quality of copper. For example, in the production of electrical copper with high conductivity, by using advanced vacuum melting technology, impurities in the copper liquid can be removed to the maximum extent to ensure the excellent electrical conductivity of the final product. These carefully cast copper ingots lay a solid foundation for subsequent processing processes, as if giving copper the initial life.
Forging: tempering the tough quality of copper
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.
Forging technology can not only significantly improve the strength and toughness of copper, but also improve its processing properties. In the aerospace field, some parts forged with copper alloys, such as key connectors for engines, are able to withstand extreme working environments with their excellent mechanical properties. In the machinery manufacturing industry, forged copper gear, shaft parts, etc., with its high wear resistance and reliability, to ensure the stable operation of mechanical equipment.
Stamping: to achieve precision forming of copper
Stamping is a kind of processing technology that applies pressure to copper through a mold to produce plastic deformation, so as to achieve precision molding. Under the action of the stamping die, a sheet of copper quickly becomes a variety of complex shapes and precise dimensions of the parts.
The stamping process has the characteristics of high efficiency and high precision, and is widely used in electronics, automobiles, home appliances and other industries. In the manufacture of electronic equipment, the stamped copper electronic component shell not only has high dimensional accuracy, but also can meet the needs of miniaturization of electronic components, and has good conductivity and electromagnetic shielding performance. In the automotive industry, stamped copper parts, such as the heat sink of the radiator, can effectively improve the heat dissipation efficiency of the car and ensure the normal operation of the engine.
Surface treatment: enhance the charm and value of copper material
Copper surface treatment process is rich and varied, electroplating is one of the
more widely used. Through electroplating, a layer of other metals, such as nickel and chromium, can be plated on the surface of copper, so as to improve the corrosion resistance, wear resistance and decoration of copper. For example, in bathroom hardware products, nickel-plated copper faucets not only look bright and beautiful, but also have good anti-rust performance, extending the service life of the product.
In addition, chemical polishing, passivation and other surface treatment processes can also effectively improve the surface quality of copper, so that it presents a unique luster and texture. In the decoration industry, surface treated copper is widely used in indoor and outdoor decoration, such as copper decorative ornaments in hotel lobbies, copper decorative lines on building facades, etc., adding luxury and artistic atmosphere to the space.
Process collaboration: Promote the development of copper processing industry
Melting casting provides the initial form for copper, forging optimizes its performance, stamping achieves precision forming, and surface treatment endows it with protective and aesthetic properties, which together promote the development of copper processing industry.
From the wide application of copper as a key conductive material in the power industry, to the important support of copper in the manufacturing of high-end equipment in the aerospace field, to the innovative application of copper in the 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.
