Customer challenge

A Vietnamese manufacturer in the A‑system VCM (Vacuum Coating Material/Magnetic tape) sector needed to scale smart production for volatile demand while improving yield and reducing downtime. The customer required a turnkey, automated line that delivered high throughput, precise micro-dispensing, and robust inline inspection to meet strict quality and traceability targets. Mingseal’s FI100 was adapted to this VCM application and has already been delivered in volume—15 production lines deployed for A‑system VCM clients.

Mingseal solution: FI100 smart LiDAR‑derived line adapted for VCM production

Leveraging the FI100’s proven automation architecture, Mingseal configured a VCM smart production line that integrates synchronized dual‑valve dispensing, dual‑track transfer, closed‑loop metrology, and intelligent handling to meet the customer’s cycle time and yield targets.

Key process adaptations and technology highlights

• Dual‑valve synchronized compensation: Two piezo/servo dispensing valves operate in perfect sync to compensate for valve drift, maintain dot uniformity and enable faster, balanced deposition across wide substrates. Synchronized operation reduces per‑station cycle time while preserving micro-dispense accuracy critical to VCM coating processes.
• Dual‑track conveyor system: A two‑rail transfer layout replaces conventional single-line conveyance, enabling parallel processing and buffer handling between stations. This architecture increases operational throughput by roughly 70% versus standard linear conveyors and supports high availability for continuous production.
• Micro‑glue automatic correction system: Inline timed weighing stations perform scheduled microbalance checks and automatically recalibrate valve parameters. The self‑correcting loop reduces manual intervention and shortens maintenance stops—saving approximately 1.5 hours of downtime per day and boosting daily capacity by about 4,500 units.
• Station consolidation and stationary processing: Following the FI100 philosophy, assembly, dispensing and curing steps are performed with the product held stationary under the robot to avoid repeated clamping. This reduces handling errors and preserves coating uniformity across sensitive VCM substrates.
• Dual‑vision guidance and AOI closed loop: Dual high‑resolution cameras provide simultaneous alignment on both sides of the product for precise dispense placement. Each station features AOI (Automated Optical Inspection) to monitor process quality in real time, enabling corrective action before defects propagate downline.
• Comprehensive sensor monitoring: Laser height sensing, pressure monitoring and torque feedback are integrated to supervise assembly, dispense volumes and cure profiles. Full data logging enables MES integration for traceability and predictive maintenance.

Production results and customer value

• Significant throughput improvement: The dual‑track and dual‑valve architecture increases operational efficiency by approximately 70% compared with legacy single‑line setups, enabling faster takt and higher output per footprint.
• High yield and consistent quality: Process control and closed‑loop correction drive a demonstrated first‑pass good rate above 99.5%, reducing scrap and rework costs in mass production.
• Reduced downtime and higher daily capacity: Automated micro‑glue calibration cuts roughly 1.5 hours of daily stoppage, translating to an additional ~4,500 units of daily output for the customer’s VCM lines.
• Improved process stability and traceability: Stationary processing, AOI feedback and MES logging provide robust process stability, easier qualification across lots, and comprehensive traceability for audits.

Conclusion

For Vietnamese A‑system VCM manufacturers, the adapted FI100 smart production line delivers a scalable, high‑yield solution combining dual‑valve compensation, dual‑track transfer and automated micro‑glue correction. With 15 lines already delivered in the A‑system VCM field, the FI100 demonstrates proven performance—boosting throughput, reducing downtime, and securing consistent product quality at scale.
