The steel industry is a heavy industry with a wide variety of products. Once mixed, major accidents can occur. Therefore, it is required that product identification must be clear and there must be QR code information for traceability. A certain steel factory has adopted an Nmark printing and labeling machine, which can generate label information through ERP and then complete the printing and labeling task of steel through PLC control. The system solves the following problems for users:
1. Prevent label pasting errors through ERP and PLC control
2. Improved work efficiency and reduced operator expenses
3. Automatic printing and labeling, with accurate and secure placement, avoiding human influence.
