Warehousing of raw materials
Receiving inspection
- When raw & subsidiary materials are warehoused, measuring weight after confirming whether it is matched to purchase specifications or not
- Gathering sample for component inspection after confirming whether foreign substances, scrap irons, etc. are mixed or not by executing appearance inspection
