Checkweighing Systems for Manufacturing Quality Assurance
1.Checkweighing systems are critical automated quality control devices used across manufacturing industries to verify product weight compliance. These systems ensure:
Regulatory compliance with trade laws (NTEP, OIML, MID)
Reduction of product giveaway (overfilling)
Detection of underfilled/defective products
Real-time process monitoring for continuous improvement
Pharmaceuticals: cGMP, 21 CFR Part 11, EU Annex 11
Food & Beverage: HACCP, ISO 22000, FDA Food Safety Modernization Act
Consumer Goods: FTC Net Contents Regulations, OIML R51
Industrial: ISO 9001, ANSI/NCSL Z540-1
In-line installation: Direct integration with filling/packaging machines
Reject synchronization: Timed ejection with downstream equipment
Closed-loop feedback: Automatic adjustment of filling machines
Statistical Process Control (SPC)
Real-time Cp/Cpk calculations
Trend analysis for predictive maintenance
Multi-lane checkweighing
Parallel weighing stations for high-volume production
Blockchain-enabled traceability
Immutable weight records for audits
Modern checkweighing systems have evolved into smart quality assurance hubs that:
✓ Ensure 100% weight compliance
✓ Provide real-time production analytics
✓ Deliver measurable ROI through waste reduction
✓ Support Industry 4.0 digital transformation
