Paste Kneading Operator (Dry Cell Battery Manufacturing)
ぺーすとねつわこう
Industry & Occupation
Classification
Summary
Responsible for the manufacturing process of preparing and mixing active material paste used in the anodes and cathodes of dry cell batteries from raw powders and additives such as binders, and finishing it to a state suitable for supply to the coating process.
Description
Paste Kneading Operators measure active material powders (such as manganese dioxide) used in dry cell battery electrodes, along with binders and solvents, in precise quantities, and use mixers and grinders to prepare a paste with the required viscosity and uniformity. As a pre-process in the manufacturing line, they manage temperature and viscosity to maintain paste quality, perform quality checks through sampling, and conduct equipment cleaning and maintenance. High-quality battery manufacturing requires precise ratio management and stable operations.
Future Outlook
Dry cell batteries support demand for small power sources such as IoT devices and remote controls. Even as automation reduces manpower, personnel responsible for stable supply of high-quality paste are still needed.
