Engineered for Precision, Built for Production
Engineered specifically for polyurethane weighing wheel production, delivering consistent quality for electronic scale and floor scale applications.
Industrial weighing wheels are critical components that directly impact the accuracy and service life of electronic scales, floor scales, and storage handling equipment. Manufacturers face ongoing challenges including inconsistent product dimensions affecting scale calibration, bubble-induced structural weaknesses reducing load-bearing capacity, and process instability leading to batch-to-batch variation. Haifeng's Weighing Wheel PU Casting Machine addresses these pain points through integrated vacuum defoaming, high-precision dosing, and independent temperature control, delivering weighing wheels with uniform density, precise dimensions, and reliable mechanical properties.The machine supports both MOCA and BDO chain extender systems, offering formulation flexibility for different hardness and performance requirements. With dosing accuracy of ≤±0.3% and automated circulation cleaning, this system ensures consistent production quality while minimizing downtime, making it suitable for manufacturers seeking to scale up industrial weighing wheel production.
Operation Workflow
Raw Material Preparation
Prepare CPU prepolymer and chain extender (MOCA or BDO) at the target mix ratio (MOCA: 100:9-12; BDO: 100:3-6) for high-load-bearing weighing wheels.
1A1B Tank Loading & Temperature Setting
Load prepolymer into Tank A and chain extender into Tank B; the 1A1B independent temperature control sets Tank A at 30-80°C and Tank B per formula (MOCA: 90-110°C; BDO: 25-50°C).
Vacuum Defoaming & Mixing
Activate the vacuum defoaming system and high-efficiency mixing to remove bubbles, delivering dense, compact wheels that withstand high-frequency use and deformation resistance.
Precision Dosing & Wheel Casting
The PLC dosing system (≤±0.3%) dispenses precisely; the mixing head runs at 7000-11000 r/min, with 50-800 g/s flow for uniform, accurate industrial weighing wheels.
Technical Specifications
The integrated PLC control system with touch screen interface enables multi-formula storage and recall, allowing seamless switching between MOCA and BDO chain extender formulations. Vacuum defoaming ensures bubble-free castings, while the automatic circulation cleaning system significantly reduces changeover time between production batches. With energy-efficient operation and configuration-specific conformity documentation reviewed on request, this machine delivers both production reliability and regulatory compliance.
