Used for weighing and marking systems in cable manufacturing

Cable production requires strict consistency in conductor weight, insulation layer thickness, and finished coil quality to meet national electrical safety standards. Prior to collaborating with our company, a large cable manufacturer in Jiangsu had been facing quality challenges. Their old manual weighing method resulted in significant weight deviations, frequent coil non-conformances, high labor intensity, and the inability to track data in real time. Even slight overweight or underweight can lead to unstable conductivity and potential short-circuit hazards in power transmission projects.
Our technical team has tailored a complete weighing and marking system for the cable coil production line. The system utilizes high-precision weighing sensor modules and is equipped with an anti-vibration filtering algorithm, achieving a weighing accuracy within ±0.02kg for coils ranging from 50kg to 2000kg. Once a stable weight value is detected, the integrated automatic coding and laser marking unit will directly print the real-time weight, batch number, production time, and conformity mark on the coil frame. Non-conforming products will trigger automatic sorting without halting the main production line.
To achieve long-term stable operation, we have added an electromagnetic interference shielding structure, which is crucial for factories filled with high-power extruders and twisting machines. After 12 months of continuous operation, the customer's coil failure rate has dropped from 8.7% to below 0.3%, and the number of manual inspectors has been reduced by 60%. The fully digital weight archive supports rapid quality audits and after-sales traceability. This case proves that intelligent online weighing can upgrade cable manufacturing from passive sampling inspection to comprehensive 100% real-time quality monitoring, thereby fully balancing production efficiency and product safety.
