2. Extruders in aluminum factories usually extrude aluminum ingots (round bars) through dies after heating. Each machine is divided into monitor, mechanic, interruption, front (adjustment) straightening, rear straightening and so on. The labor intensity is not very great, but many factories implement two shifts, one shift 12 hours, and the working hours are very long.
3. Generally, there are startup, clamping, straightening, interruption, framing, etc. Because aluminum generally melts at high temperature, aluminum extrusion is generally carried out at a temperature higher than room temperature, which is generally uncomfortable in summer, and the air in the whole workshop is hot. Winter is not very pleasant, because the metal in hand is basically metal, and the feeling of metal is generally lower than the ambient temperature when the temperature is relatively low in winter.
