Client: Top Manufacturing Industries
Industry: Premium Home Fragrance & Product Manufacturing
Technology Provider: SunBio IT Solutions (Bengaluru, India)

Overview & Challenge

Inconsistent Quality and Bottlenecks in Production

Manual visual inspection at the wax-filling stage led to alignment inconsistencies, human errors, and reduced throughput. The process required dedicated QC personnel and created a bottleneck in achieving optimal production speed.

  • Alignment Inconsistencies: Misaligned candle wicks caused severe product rework and raw material wastage.
  • Manual Counting Errors: Human counting errors impacted batch integrity and warehouse inventory tracking.
  • Production Bottlenecks: Sluggish manual quality checks restricted overall factory throughput.
The SunBio Solution

AI-Powered Vision Automation for Precision QC

SunBio IT Solutions implemented an industrial vision automation solution featuring real-time object detection using dual high-speed GigE cameras and machine learning models trained specifically for high-precision candle alignment and counting.

  • AI Object Detection: Achieved $\pm 0.5\text{ mm}$ accuracy tolerance for automatic wick alignment verification.
  • Automated Gate Control: PLC-integrated stop signal system that automatically flags and diverts misaligned trays.
  • Continuous Monitoring: Real-time automated feedback loops for uninterrupted industrial production control.
