Ultra-Precision Metering
±0.3%-±1% accuracy with precision gears/pistons; stable flow ensures consistent polyether-PU ratio for uniform foam density.
Polyether-Adapted Corrosion Resistance
Special alloy/PTFE contact parts + double shaft seals resist polyether/isocyanate, preventing leaks and material contamination.
Low-Pulsation Stable Output
Optimized fluid channels minimize pulsation (<1%), avoiding bubbles during raw material mixing for smooth flat foam molding.
Flexible Flow Adjustment
Supports manual handwheel tuning or auto PLC/VFD control, quickly adapting to diverse foam thickness and density requirements.
Low-Noise & Durable Design
Structural optimization keeps noise <65dB; wear-resistant components and sealed bearings enable long-term continuous operation.
Easy Installation & Maintenance
Compact size fits production lines; standard ports for quick connection, detachable parts simplify cleaning and upkeep.
