copper bars
Small size extruded copper bars:
Oxygen-free copper rod → Extrusion by extruder → Straight effect → Computer fixed length measurement → Cutting → Processing → Packaging → Warehousing
Large size extruded copper bars:
Oxygen-free copper rod → Extrusion by extruder → Rolling → Straightening → Computer fixed length measurement → Cutting → Processing → Packaging → Warehousing
Extra Large Size Extruded Copper Bar:
Standard material selection → melting → casting → calendering → rolling → milling → machining (drilling, bending, tin plating) → packaging → warehousing
