What are the main daily work contents of being an extrusion technician in an aluminum profile production enterprise? Is there any development prospect in doing this? What is the salary?

The production of aluminum profiles is to melt and cast aluminum alloy bars first, and then extrude the profiles. After passing the inspection, there are two treatment processes, one of which does not need heat treatment and can be sold after packaging. Another important thing is aging (precipitation strengthening), then surface treatment (oxidation, spraying), packaging and sales after inspection. This is an assembly line operation. The amount of aluminum profile is large, and the prospect is good. The wages of different factories vary greatly, from about 3,000 to about 6,000 for ordinary workers.
