Industry & Occupation
Classification
Summary
A job that performs quality inspections on dimensions and physical properties of metal intermediate products (semi-finished products) and confirms product conformity in the manufacturing process.
Description
Intermediate Product Inspectors (Metal) perform dimensional measurements using calipers, micrometers, or 3D measuring machines; hardness tests with hardness testers; chemical composition analysis with spectrometers; and non-destructive tests such as ultrasonic flaw detection and magnetic particle testing on metal semi-finished products like castings, rolled materials, and extruded materials. They record measurement and test results, compare them against JIS and ISO standards to determine conformity, report defect causes, and propose improvements. They also calibrate and maintain inspection equipment and collaborate with manufacturing departments to support quality improvement.
Future Outlook
While manufacturing sites are advancing in automation and IoT, demand for inspection technicians with advanced measurement and analysis skills is expected to remain stable. Acquisition of non-destructive testing and data analysis skills is important.
