Automated Checkweighing for Lean Manufacturing

Automated Checkweighing for Lean Manufacturing

1. Introduction to Lean Checkweighing

Automated checkweighing systems are essential tools for implementing lean manufacturing principles, eliminating waste while ensuring product quality. These systems deliver:

• 100% weight verification without slowing production

• Real-time process control to minimize overfill (reducing giveaway)

• Automated data collection for continuous improvement

• Immediate defect detection supporting Jidoka (autonomation) principles

2. Waste-Reducing Features

• Giveaway Control

  • Dynamic weight target adjustment

  • Statistical process control (SPC) limits

• Material Savings

  • 0.5-1.5% reduction in overfill

  • Automated feedback to filling machines

3. Continuous Improvement Tools

• PDCA Cycles

  • Plan: Analyze weight variation patterns

  • Do: Implement auto-fill compensation

  • Check: Verify giveaway reduction

  • Act: Standardize new parameters

• Six Sigma Integration

  • Cp/Cpk monitoring for process capability

  • DMAIC for chronic weight variation

4. Conclusion

Automated checkweighing systems enable lean manufacturing by:
✓ Eliminating measurement waste through precision weighing
✓ Supporting jidoka with instant defect detection
✓ Enabling data-driven kaizen with real-time analytics
✓ Reducing costs through optimized material usage

SMARTWEIGH INSTRUMENT CO.,LTD , established over 15 years, which is one of the largest manufacturers and exporter in China. Our workshop occupy 20,000 square meters and located in a very convenient and beautiful city, Changzhou, it is close to Shanghai and only take one hour by high speed railway.

Our company have advanced production equipments like Bending machine, pre-arch machine, shearing machine, qutomatic welder, automatic welding robot, plasama cutting machine, and baking paiting room, to help us increase the product quality and production productivity Our company also have the senior technician team and design team. Many products have been applied patents.

Under the advanced test equipement, technical workers and rich experice, we manufactured high qualified truck cales, platform scales, bench scales, crane scales, highway axle scales, as well as spare parts like indicators and loadcells. We have exported to RUSSIA, KSA, USA, UK, HOLLAND, SPAIN, ITALY etc many different kind of countries, our good quality and timely delivery has attracted over 200 long term distrbutors all over the world.

Our yearly export collection amount keep about 5000,000 to 10000,000 USD, among of this, our project for the foreign railway, highway and government is the majority. By the way, We can supply both ODM and OEM design also.

Our company havs been awarded ISO 9001, CE, SGS, OIML cetificate for our products, all weighing scales are

pre-calibrated before shipping, We deicated to the spirit of " Quality come first forveve and technology detemines the productivity"since extablished, and we have benifited from it and quietly brilliant for over 15 years.

More and more wonders and brilliant future will be made be by SMARTWEIGH!
