Why is automatic weighing & batching crucial for rubber compounding, and what’s its advantage over manual batching?

Rubber compounding is the “source” of rubber product quality, and the ratio accuracy of raw materials directly determines the final performance of rubber strips/seals. Automatic weighing & batching relies on PLC intelligent control + high-precision load cells (accuracy ≤±0.1g) to realize precise batching of raw rubber, additives, and vulcanizing agents. Compared with manual batching, it eliminates human error (performance deviation of rubber compound ≤±3%), improves batching efficiency by 3-5 times, and records all data in real time for traceability—fully meeting the quality management requirements of IATF 16949/ISO 9001.
