Discussion on Copper Shaped-section Processing Technology

Copper shaped-sections are metal profiles produced from copper alloys through specific processing techniques, resulting in sections with varying shapes and sizes. Copper shaped-sections are known for their excellent conductivity, thermal conductivity, and corrosion resistance and are widely used in electronics, electrical appliances, communications, construction, transportation, and other fields. With the advancement of technology and the continuous progress of industrial production, the processing technology and quality requirements for copper shaped-sections have become increasingly stringent. This article will explore the processing technology of copper shaped-sections.

I. Processing Methods for Copper Shaped-sections

1. Casting Method

The casting method is the most common method for producing copper shaped-sections. This method involves pouring molten copper alloys into molds to obtain the desired shapes and sizes. The advantages of the casting method are simple production equipment, low processing costs, and suitability for mass production of complex-shaped copper shaped-sections. However, the casting method has disadvantages such as low dimensional accuracy, poor surface quality, and the inability to produce thin-walled, slender structures with complex shapes.

2. Extrusion Method

The extrusion method involves forcing molten copper alloys through an extruder to obtain the required shapes and sizes. The advantages of the extrusion method are high production efficiency, high dimensional accuracy, and good surface quality, making it suitable for mass production of simple-shaped copper shaped-sections. However, the equipment investment is high, and processing costs are high, and it is unable to produce complex-shaped copper shaped-sections.

3. Stretching Method

The stretching method involves stretching copper alloy sheets or rods through a stretching machine to obtain the desired shapes and sizes. The advantages of the stretching method are high dimensional accuracy, good surface quality, and high strength and hardness of the produced copper shaped-sections. However, the production efficiency is low, and processing costs are high, making it suitable for small batch production of high-precision copper shaped-sections.

4. Bending Method

The bending method involves bending copper alloy sheets or rods through a bending machine to obtain the required shapes and sizes. The advantages of the bending method are simple production equipment and low processing costs, making it suitable for the production of simple-shaped copper shaped-sections. However, the produced copper shaped-sections have low dimensional accuracy, poor surface quality, and are unable to produce complex-shaped copper shaped-sections.

II. Development Trends in Copper Shaped-section Processing Technology

1. High-Precision Processing Technology

With the advancement of technology, the dimensional accuracy and surface quality requirements for copper shaped-sections are becoming higher. Therefore, high-precision processing technology will become one of the development trends in copper shaped-section processing technology. High-precision processing technologies include CNC machining, laser cutting, and electrochemical machining.

2. Hybrid Processing Technology

Hybrid processing technology involves combining two or more processing methods to achieve better processing results. Hybrid processing technology can improve the processing efficiency, dimensional accuracy, and surface quality of copper shaped-sections. For example, the combination of casting and extrusion methods can be used to first produce complex-shaped copper shaped-sections through casting and then finish them with extrusion.

3. Energy-saving and Environmentally-friendly Processing Technology

As people become more environmentally conscious, energy-saving and environmentally-friendly processing technology will become one of the development trends in copper shaped-section processing technology. Energy-saving and environmentally-friendly processing technologies include low-temperature cold drawing and high-efficiency casting. These technologies can reduce energy consumption and environmental pollution while improving production efficiency.

In summary, copper shaped-section processing technology in our country has made significant progress, but there is still much room for development. In the future, copper shaped-section processing technology will develop towards high precision, hybrid processing, and energy conservation and environmental protection. At the same time, with the application of artificial intelligence, big data, and other technologies, copper shaped-section processing technology will become more intelligent and automated to meet the increasingly stringent production and quality requirements.
