Abstract：

The continuous extrusion technology as an efficient mode method of production has been massively used in nonferrous metal industry. The continuous extrusion process, extrusion process parameters selection, overall structure of mould, mould design and material selection for copper alloy were studied, and the continuous extrusion experiment on CuMg0.3 alloy was conducted, furthermore the copper busbar was successfully extruded. The result shows that the continuous extrusion process, selection of extrusion process parameters, mold design and selection of mold material are reasonable, and the selected continuous extrusion machine can provide driving force for busbar forming of CuMg0.3 alloy. Copper-magnesium alloy extrusion process and mould design can provide a reference for the continuous extrusion process and mould design of other copper alloy materials with shapes ranging from profiles, sheet, to strip.
