| Abstract: |
| In the production of tire compound，manual weighing of powder materials with very small amount was affected by human factors，which was prone to problems such as taking wrong material，inaccurate weighing，cross contamination，lack of record and control in the production process. That could easily lead to tire quality problems in the later stages，and the problems could not be traced back to the source.A semi-automatic accurate weighing and data traceability control system of the powder materials which
were used in small amount in the production process was designed. Its operation process was as follows：obtaining the production data such as work orders，production formulas and material information through MES（Manufacturing Execution System），preparing materials according to the requirements of work orders，putting the material into the silo station，printing the barcode information on the powder storage bag by the code printer，and weighing small amount of powder materials according to the formula.The actual application of the system in the tire factory showed that it could effectively control and trace the weighing process of small amount of powder materials. |
