Changzhou Mingseal Robot Technology Co., Ltd.

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.

Customer challenge An Algerian medical device manufacturer scaling production of dynamic blood glucose test strips faced tight cost targets while needing sub-microliter reagent control. Existing manual and slow jetting methods delivered inconsistent reagent volumes, high material waste and reduced enzyme activity from aggressive handling. The line required a compact, easy-to-integrate valve that could deliver repeatable micro-dosing, preserve reagent bioactivity, and stabilize throughput for long production runs. Mingseal solution: KPS2000 piezo jet valve system Mingseal supplied the KPS2000 piezo jet valves and a lightweight controller to meet the customer’s technical and cost constraints. The KPS2000 is a non-contact, high-frequency jet valve optimized for micro-volume reagent coating on sensitive biosensor pads. Key features applied in the Algerian line: Sub-nanoliter precision and high throughput: With jetting up to 1200 Hz and minimum droplet sizes in the nanoliter/sub-nanoliter range, the KPS2000 enables tight shot-to-shot volume control while meeting takt rates—reducing over‑apply and material cost per strip. Broad viscosity compatibility: The fluid path supports viscosities from 1 to 500,000 mPa·s, allowing enzyme suspensions, stabilizers and viscosity modifiers to be processed without frequent hardware changes. Lightweight, compact design: A 430 g valve body and compact controller simplify gantry or robot mounting, maintaining timing fidelity at high speed and easing retrofits on existing lines. Gentle fluid handling: Valve actuation and nozzle geometries are engineered to minimize shear and thermal stress, preserving enzyme structure and activity during dispensing. Process integration and control Implementation focused on reproducible coating recipes and closed‑loop control to guarantee uniform films across long runs: Multi-head synchronized dispensing: Four KPS2000 valves were mounted on a lightweight gantry and run in parallel to coat reagent pads simultaneously. High-frequency synchronization preserved droplet timing and uniformity across heads. Temperature and pressure management: Independent temperature control for syringes and tuned back-pressure settings maintained consistent reagent rheology. Low-energy pulses and controlled nozzle geometry prevented local heating and high shear. Inline metrology and feedback: Optical thickness measurement combined with periodic gravimetric sampling provided real-time verification of dot mass and film uniformity. Dispense parameters were auto-corrected for drift to maintain mass within tolerance. Preventive maintenance and fluid hygiene: Scheduled purge cycles and nozzle-change protocols reduced clogging and downtime, lowering consumable waste and maintaining stable runs. Results and production value Tight micro-volume control and cost savings: Shot-to-shot variance dropped to below 3%, cutting reagent overuse and materially reducing per-strip reagent costs at scale. Uniform sensor response and yield improvement: Consistent film thickness and line-width produced tightly clustered QC results, decreasing lot-to-lot variability and reject rates. Preserved reagent activity: Low-shear, low-temperature dispensing preserved enzyme activity and shelf-life, supporting regulatory consistency for clinical test strips. High throughput with simple integration: The KPS2000’s high-frequency capability and lightweight mounting allowed the plant to meet forecasted takt rates without major equipment redesign. Lower maintenance overhead: Improved fluid-path design and preventive maintenance decreased unscheduled stops and consumable waste, increasing overall equipment effectiveness. Conclusion For Algerian manufacturers producing dynamic blood glucose test strips, the KPS2000 provides an economical, high-precision jetting solution that balances micro-volume accuracy, reagent protection and production stability. By combining sub-nanoliter jetting, wide viscosity tolerance, gentle dispensing and closed-loop metrology, the KPS2000 reduces cost per unit while improving uniformity and preserving bioactivity—making it an effective choice for scalable, regulatory-compliant strip production.
