Industry & Occupation
Classification
Summary
This occupation handles the process of filling electrode plates with paste, forming, and homogenizing them in the lead-acid battery manufacturing process. It ensures product performance through machine operation, measurement, and quality control.
Description
Paste filling workers, in the electrode plate manufacturing process for lead-acid batteries, fill a certain amount of viscous paste (a mixture of lead powder, aqueous sulfuric acid solution, and additives) from raw materials set in the filling machine, and use spatulas or rollers to uniformize the thickness and form it. They handle accurate filling using machine operations and measuring instruments, visual inspections to check compliance with product specifications, and sorting of defective products. The work is line-based, requiring simple equipment maintenance and cleaning, as well as safety and health management.
Future Outlook
While automation progresses and reduces workload, demand for conventional lead-acid batteries may gradually decline due to the impact of EV adoption and new material introductions. The importance of safety and quality control remains high, requiring skill acquisition and improvement activities.
