Introduction
For food, nutraceutical, pharmaceutical and daily chemical manufacturers worldwide, inconsistent package weight has always been a core headache that triggers huge losses: underweight products lead to retail fines, consumer complaints and brand reputation damage; overfilled packages cause continuous waste of raw materials and shrink profit margins. Manual random sampling can not achieve 100% full inspection, while low-precision weighing equipment generates frequent false rejects and interrupts continuous production.
Shanghai Fanchi-tech Machinery Co., Ltd independently developed the series of conveyor online checkweighers, perfectly matching packaging lines for small & medium cartons, blister packs, sachets, snack pouches and cosmetic boxes. This fully stainless steel automated weight recheck machine integrates high-resolution load cell, multi-language touch HMI, automatic pneumatic rejection and complete data traceability function, which has become the top quality control equipment chosen by hundreds of manufacturers across Europe, Southeast Asia, Australia and North America.
Core Structural & Performance Advantages of Fanchi-tech Checkweigher (Matching Real Workshop Machine Photos)
1. Full 304 Brushed Stainless Steel Sanitary Frame, Washdown Available
The whole machine body, support stand and conveyor frame adopt food-grade 304 stainless steel seamless welding structure, no residual dead corners for powder, oil and food residue. Smooth matte surface resists corrosion of sanitizer, supports daily high-pressure water washing, fully meets GMP, HACCP, BRC international hygiene standards for food and pharmaceutical factories.
Four adjustable stainless steel leveling feet ensure stable weighing even in factories with ground vibration, effectively filtering mechanical vibration interference from upstream filling and packaging machines.
2. Compact Integrated Control Cabinet & Intuitive Touch Screen Operation
Independent vertical control cabinet is placed on the side of the weighing tunnel, equipped with 7-inch industrial color touch screen, physical emergency stop button, three-color tower light status indicator. Multi-language system supports English, Spanish, French, Russian, Arabic, etc., one-click storage of up to 100 product recipes, rapid switching of different SKUs without repeated parameter calibration.
Built-in independent data storage module, inspection data including total output, qualified quantity, overweight/underweight reject data can be exported via USB or Ethernet port, providing complete audit data for retailer and third-party regulatory inspection.
3. FDA Food-Grade PU Conveyor & Gentle Automatic Rejection Mechanism
The white anti-static PU conveyor belt is oil-proof, wear-resistant and easy to disassemble for deep cleaning, suitable for fragile products such as pharmaceutical blister boxes, chocolate cartons and soft plastic sachets without scratch damage.
Built-in pneumatic push-rod rejection system with adjustable thrust; once the checkweigher detects overweight or underweight products, the push rod will automatically push unqualified goods to the locked reject bin without stopping the main production line, greatly improving overall line efficiency.
4. Stable High Precision Weighing Module, Wide Application Weight Range
Adopts imported high-stability load cell, the mainstream model FA-CW230 covers 3g–200g weighing range, best accuracy up to ±0.1g (3σ). It can stably detect tiny weight deviation of small packaged goods, effectively helping customers cut overfilling loss by more than 90%.
Support customized weighing platform size, conveyor width and line height, seamlessly dock with vertical packing machines, horizontal flow wrappers, carton sealing machines, metal detectors and X-ray inspection equipment to form a full automatic quality control production line.
5. Complete Safety Configuration & Global Standard Certifications
Standard configuration: emergency stop button, running safety interlock, overload protection, sound-light abnormal alarm. All machines pass CE, ISO9001, ISO14001 certification, fully meet EU, UK, US, Southeast Asia market import standards, no customs clearance obstacles.
European OTC Pharmaceutical Manufacturer Eliminates Weight Non-Compliance Risk
Client Information
Company Name: MediCare Pharma GmbH
Location: Germany, Bavaria
Production Scope: Over-the-counter medicine blister cartons, vitamin sachets, oral probiotic boxes, 65+ product SKUs, supplying German national pharmacy chains and supermarket drug counters.
Main Pain Points Before Cooperation with Fanchi-tech
- Only 8% of products were manually spot-checked every hour, dozens of underweight medicine cartons flowed into retail terminals every month, resulting in formal warnings from local food and drug supervision bureau and multiple customer refund complaints.
- To avoid underweight penalties, filling workers deliberately added extra raw powder, the average overfilling rate reached 3.2%, causing annual raw material waste loss of more than 78,000 Euros.
- The previous old weighing machine had unstable data, could not store production records, and could not provide complete weight inspection reports for quarterly retailer supplier audits, facing the risk of being removed from the supplier list.
After video line survey and product weighing test, Fanchi-tech recommended 6 sets of FA-CW230 online checkweighers, matched with short-distance pneumatic push rod rejectors, adjusted the weighing platform size to adapt to 20–180g medicine cartons, and connected the data export port to the customer’s factory MES quality management system. Our engineers completed on-site installation, equipment calibration and operator training within 3 working days after the machines arrived at the customer’s workshop.
Measurable Improvement Results After 6 Months of Operation
- 100% full automatic online inspection realized, zero underweight product outflow, no regulatory warning or customer weight complaint received again.
- Overfilling rate dropped from 3.2% to 0.15%, saving about 73,000 Euros of raw material cost per year, greatly boosting gross profit of finished medicine products.
- Automatic continuous data logging meets all audit requirements; the customer successfully passed the annual pharmacy chain supplier evaluation and obtained 2 new large bulk orders.
- 4 manual sampling inspectors were reassigned to other quality control posts, cutting long-term labor expenditure for the packaging workshop.
“Fanchi-tech’s checkweigher is stable, easy to clean and operate. The accurate weighing and complete data recording solved our biggest weight compliance trouble. Their after-sales team provides fast remote technical support whenever we have operation questions.”
— Mr. Schmidt, Quality Manager of MediCare Pharma GmbH
