Why Precision Matters in Industrial Coating
Uneven coating layers result in product defects, recalls, and compliance risks—particularly in regulated industries like aerospace or medical devices. Our [electrical proportional valves] solve these challenges through closed-loop pressure control that adapts to:

  • Substrate Variations: Compensate for porous vs. non-porous materials instantly.

  • Environmental Shifts: Auto-adjust for humidity/temperature-driven viscosity changes.

  • Line Speed Fluctuations: Maintain ±3% thickness tolerance at 5–50 m/min.


Key Features Driving ROI

  1. True Stepless Control
    Eliminate pressure spikes with 0–100% modulation granularity, critical for:

    • Delicate electronics conformal coating

    • High-speed food packaging film coating

  2. Remote Process Optimization

  3. Industry-Specific Certifications

    • ATEX compliance for explosive environments (e.g., powder coating).

    • FDA-grade materials for pharmaceutical/food contact surfaces.

how electro-pneumatic proportional valves revolutionize coating processes through:

  1. Adaptive Pressure Profiling

    • Real-time adjustment of fluidizing air pressure (0.5–10 bar) to match substrate geometries.

    • 0.1-second response time eliminates overspray during speed changes.

    • Pre-programmed recipes for gloss/matte finishes or multi-layer coatings.

  2. Cross-Process Flexibility

    • Single-valve compatibility with spray, dip, and roll coating systems.

    • Auto-switching between high-viscosity (50,000 cP) and low-viscosity (<100 cP) materials.

  3. IoT-Driven Efficiency

    • Monitor coating thickness (±2µm) via integrated pressure-flow algorithms.

    • Predictive maintenance alerts for nozzle wear or pressure drift.

    • Energy savings up to 25% via demand-based compressor control.

Case Study: Industrial Paint Coating
A heavy machinery manufacturer achieved:

  • 22% Reduction in Paint Waste: Precise edge control eliminated overspray.

  • 15% Faster Line Speed: Dynamic pressure ramping during part entry/exit.

  • Zero Rework: Consistent 8–12µm coating thickness across irregular surfaces.
