**Company**: A mid-sized consumer electronics manufacturer.
**Problem**: Slow assembly lines for wireless earbuds. The old system used manual bins to pass parts, leading to frequent falls and delays. Defective parts were high (12% of units) due to static damage.
**Solution**: Implemented the 38mm yellow aluminum
roller track with side guides, paired with
lean pipe workbenches and ESD workstations.
**Results**:
1. 25% increase in assembly speed.
2. 15% reduction in defective parts (down to 1.8%).
3. 10% decrease in inventory costs (thanks to the pull system).
4. 20% reduction in time spent looking for lost parts.
