FA-CW300 Checkweigher: Precision Weight Control for Small-Packaged Food & Nutraceutical Products
For manufacturers of small-packaged food, nutraceuticals, and consumer goods, accurate weight control is critical to meeting regulatory standards, reducing material waste, and protecting brand reputation. Even minor underfills or overfills in small packages can trigger costly penalties, customer complaints, and eroded market trust. ThaiSnack Wellness Co., Ltd., a leading producer of premium herbal tea bags, nut snacks, and vitamin supplements in Thailand, turned to Shanghai Fanchi-tech Machinery Co., Ltd. to solve its weight inspection challenges. By deploying our FA-CW300 Checkweigher, ThaiSnack Wellness eliminated weight variation risks, cut waste, and secured long-term compliance with Thai FDA and EU food safety standards.
The Challenge: Weight Inconsistency & Production Bottlenecks in Small Packaging
ThaiSnack Wellness produces over 100,000 small-packaged items daily, including 20g herbal tea bags, 50g roasted nut pouches, and 80g vitamin tablet bottles. In early 2025, a batch of 20g tea bags was found to have an average underfill of 0.8g, triggering a warning from the Thai Food and Drug Administration (FDA) and a temporary production suspension. The company’s legacy checkweighing system exposed critical flaws:
- Insufficient Precision: The old checkweigher had a measurement tolerance of ±1g, failing to detect the 0.8g underfill in 20g tea bags, which violated EU weight labeling regulations.
- High False Reject Rates: Lightweight small packages frequently shifted or tipped on the old system’s narrow belt, leading to a 12% false reject rate—wasting 12,000 qualified items weekly, costing THB 9,000 (≈€235) in monthly material losses.
- Slow SKU Switching: Manual calibration between different product formats (tea bags, nut pouches, vitamin bottles) slowed production by 24% during peak demand periods.
- Hygiene Gaps: The old machine’s crevice-ridden design trapped food residues, creating bacterial growth risks and failing BRCGS audits, threatening the company’s export license to the EU.
“Our small-packaged wellness products are our core competitive edge, but weight inconsistency and production inefficiencies were putting our brand and compliance at risk,” says Nara Srisuk, Operations Director at ThaiSnack Wellness. “We needed a compact, precise checkweigher built to handle diverse small-packaged formats without compromising speed or hygiene.”
The Solution: Fanchi-tech FA-CW300 Checkweigher for Small Packaging
After evaluating 7 competitors, ThaiSnack Wellness selected the FA-CW300 Checkweigher for its ultra-compact design, high precision, and food-grade construction. As shown in our factory photos (ready for export with wooden crating), the FA-CW300 features a full 304 stainless steel frame, stable three-stage white conveyor belt (infeed, weighing, outfeed), touch-screen control panel, emergency stop button, and adjustable anti-vibration support legs—all engineered for small-packaged food and nutraceutical production lines, with export-ready packaging to ensure safe delivery to global markets.
1. Ultra-High Precision for Small Packages
The FA-CW300 uses high-resolution load cells and advanced digital signal processing to achieve measurement accuracy of ±0.1g, even for 20g tea bags and 50g nut pouches. Key capabilities:
- Micro-Deviation Detection: Identifies underfill/overfill deviations as small as 0.5g, ensuring full compliance with Thai FDA and EU weight accuracy requirements.
- High-Speed Operation: Processes up to 160 small packages per minute, matching ThaiSnack’s packaging line speed.
- Adaptive Calibration: Automatically adjusts to different package sizes and materials (paper, plastic, aluminum), eliminating manual calibration between SKUs.
During on-site validation, the FA-CW300 detected 100% of test underfill and overfill conditions in 20g tea bags, 50g nut pouches, and 80g vitamin bottles.
2. Stable Conveying for Fragile Small Packages
The FA-CW300’s conveyor system is optimized for lightweight, fragile small packages:
- Smooth Belt & Guide Rails: Prevents small packages from shifting or tipping during weighing, ensuring consistent positioning and accurate readings.
- Soft Reject Mechanism: Pneumatic reject arms gently remove non-conforming packages from the line without damage, reducing waste by 32%.
- Compact Footprint: The streamlined design fits into tight production floor spaces, ideal for small-scale or mid-sized manufacturing facilities.
3. Hygienic Design & Intelligent Compliance
The FA-CW300’s crevice-free 304 stainless steel construction supports daily high-pressure washdowns, while its food-grade white belt resists residue buildup. Key features:
- Easy-to-Clean Surfaces: Seamless stainless steel surfaces eliminate hidden crevices, reducing cleaning time by 38% and minimizing bacterial growth risks.
- Fast SKU Switching: The touch-screen control panel stores 40+ product presets, enabling SKU switching in 12 seconds—down from 15 minutes with manual calibration.
- Audit-Ready Traceability: Logs 1,000,000+ weight records (including time-stamps and batch numbers) in a secure database, providing full traceability for Thai FDA and BRCGS audits.
The Outcome: Zero Regulatory Warnings & 22% Faster Production
In the 9 months since deploying 5 FA-CW300 Checkweighers across ThaiSnack Wellness’ production lines:
- 41 Critical Weight Deviations Intercepted: Detected deviations as small as 0.5g in small packages, preventing 3 potential regulatory warnings and THB 65,000 (≈€1,700) in estimated recall costs.
- 93% Reduction in False Rejects: Weekly package waste dropped from 12,000 to 840, saving THB 8,300 (≈€217) monthly in material and labor costs.
- 22% Faster Production: Fast SKU switching and stable conveying increased line efficiency, adding 10 hours of weekly capacity during peak holiday demand.
- 100% Audit Compliance: Passed all Thai FDA and BRCGS inspections with zero non-conformities, securing a 3-year export contract to the EU worth THB 2.2 million (≈€57,500).
- Low Maintenance Costs: The robust 304 stainless steel design reduced annual maintenance expenses by 30% compared to legacy machines.
“The FA-CW300 didn’t just fix our weight control problem—it transformed our small-packaging operations,” says Srisuk. “We now have complete confidence that every small package leaving our facility is accurate, compliant, and safe for consumers.”
