FA-CW800 Checkweigher: Precision Weighing for Large Carton Packaging Lines

 
For manufacturers shipping large, retail-ready cartons, even a 20g weight discrepancy can lead to costly retail chargebacks, compliance failures, or logistics inefficiencies. This is why NordicPro Foods—a leading Scandinavian producer of 5–20kg bulk cartons of organic grains, specialty flours, and premium dried fruits—partnered with Shanghai Fanchi-tech Machinery Co., Ltd. to deploy our FA-CW800 Checkweigher (the roller-conveyor units pictured in our production facility). The system has transformed their end-of-line quality control, delivering precise weighing for large cartons while keeping pace with their high-throughput operations.
 

 

Company Background: Bulk Carton Production for Retail & Foodservice

 
NordicPro Foods supplies over 120 metric tonnes of 5–20kg bulk cartons weekly to major European retailers (including ICA and Coop) and foodservice distributors. Their products, from 5kg organic oat cartons to 20kg dried fruit bulk packs, require strict weight accuracy to meet EU weights-and-measures regulations and avoid retailer penalties.
 
Before adopting the FA-CW800, the company relied on manual spot-checks, which:
 

  • Only sampled 1 in 20 cartons, missing up to 15% of underfilled or overfilled units
  • Created a bottleneck in their 8-cartons-per-minute line
  • Generated no digital weight logs, risking audit failures and chargebacks

 

 

The Challenge: Large Carton Weighing Hurdles

 
Large, rigid cartons present unique challenges that generic checkweighers cannot address:
 

  1. Tight Weight Tolerances: Retailers required ±15g accuracy for 5–20kg cartons, a threshold their old manual checks couldn’t consistently meet.
  2. Carton Stability: Rigid 5–20kg cartons often shifted on belt conveyors, causing weighing inaccuracies.
  3. High Throughput: The line runs at 8 cartons per minute, so the checkweigher must keep pace without delays.
  4. Hygiene for Food Products: Organic grain dust and dried fruit crumbs demanded a washdown-compatible design.

 

 

The Solution: FA-CW800 Checkweigher 

 
After on-site testing with their large carton samples, NordicPro selected the FA-CW800 for its tailored performance:
 

1. Roller Conveyor for Large Carton Stability

 
The FA-CW800’s heavy-duty stainless-steel roller conveyor (visible in the images) stabilizes rigid 5–20kg cartons, preventing the shifting that plagues belt-based systems. It maintains ±10g accuracy across the full weight range, exceeding the retailer’s ±15g requirement.
 

2. High-Speed Throughput

 
The system syncs seamlessly with their 8-cartons-per-minute line. Its automated side-push reject mechanism diverts non-compliant cartons to a dedicated rework station, with zero disruption to throughput.
 

3. 60-Second SKU Switchovers

 
The touchscreen control panel stores pre-programmed settings for 5kg, 10kg, 15kg, and 20kg cartons. Operators select the SKU, and the system auto-adjusts weight tolerances and conveyor speed—cutting changeover time from 10 minutes to 60 seconds.
 

4. Automated Compliance Logs

 
The FA-CW800 generates real-time, exportable weight logs that include:
 

  • Individual carton weights
  • Reject rates per shift
  • Batch-level accuracy reports

 
These logs helped NordicPro pass its 2025 BRC audit with zero compliance findings.
 

5. Hygiene-First Build

 
The all-stainless-steel (304 grade) construction features:
 

  • Crevice-free roller gaps that resist grain dust and crumb buildup
  • IP65-rated washdown compatibility for weekly deep cleaning

 

 

The Outcome: Tangible Results for NordicPro Foods

 
Since installing 3 FA-CW800 units:
 

  • 0 Retail Chargebacks: They have not received a single weight-related fine, saving €6,800 annually.
  • 99.8% Carton Accuracy: The system catches 99.8% of underfilled/overfilled cartons, up from 85% with manual checks.
  • 15% Faster Line Efficiency: Faster changeovers and automated weighing added 2.2 hours of daily production capacity.
  • Reduced Labor Costs: Automated logs eliminated the need for 2 full-time quality auditors.

 
“The FA-CW800 is built for our large cartons— it handles our 20kg dried fruit packs with the same precision as our 5kg oat cartons, and the roller conveyor keeps everything stable,” says Erik Johansson, NordicPro’s Operations Manager. “We’ve already ordered an additional unit for our new specialty flour line.”
 

 

Why the FA-CW800 for Large Carton Producers?

 
For brands like NordicPro, the FA-CW800 delivers:
 

  • Carton-Specific Stability: Heavy-duty roller conveyor design prevents shifting and ensures accuracy for large, rigid cartons.
  • Broad Weight Range: Maintains precision from 5kg to 20kg.
  • Retail-Ready Compliance: Automated logs that meet global food safety standards.

 

 

Next Steps: Test the FA-CW800 with Your Cartons

 
If you’re a manufacturer of large carton products struggling with weight accuracy or slow changeovers, contact Kerry Wang to arrange a virtual or on-site demo of the FA-CW800. We’ll test the unit with your specific carton sizes and weights to prove its performance.
