How to Select the Right Multihead Weigher for Your Production Line

For manufacturers designing or upgrading a packaging line, choosing the right multihead weigher goes far beyond selecting a machine with the right number of heads. A well-chosen weigher becomes a central driver of efficiency, accuracy, and sustainable cost control. With options ranging from compact 10-head units to high-performance 32-head systems, the challenge lies in matching the machine’s capabilities to real production conditions. This guide reframes the selection process from a system-level viewpoint and highlights why Guangdong Kenwei Intellectualized Machinery Co., Ltd. is a preferred partner for factories worldwide.

1. Start With a Clear Understanding of Your Product Behavior

Every product behaves differently during feeding, weighing, and discharge, so the weigher must be matched to its physical characteristics.

Consider: Type and flowability: granular, powdery, fragile, sticky, or irregular shapes.

• Weight and size variation: high-consistency or high-variability products. 
• Moisture and oil content: may require anti-stick or special surface treatments. 
• Fragility: snacks such as chips and cookies require gentle handling solutions. 

Accurate knowledge of product behavior guides decisions on hopper structure, vibration settings, and algorithm tuning.

 2. Plan the Required Line Capacity

Not Just Machine Speed Production goals differ across facilities. The weigher must align with the desired throughput of your entire packaging line: 

• Small operations: 20–50 bags/min 
• Mid-size manufacturers: 80–150 bags/min 
• High-speed lines: 200+ bags/min 

Weigher configurations—10, 14, 16, 24, or 32 heads—directly influence combination possibilities and, therefore, output speed. Kenwei provides configurations optimized for every level of production, ensuring stable accuracy even at high speeds. 

3. Focus on Accuracy to Minimize Waste and Maintain

Compliance Weighing precision is one of the biggest contributors to cost savings. Key factors include: 

• Sensor quality: digital load cells outperform analog sensors. 
• Algorithm optimization: intelligent combination algorithms reduce giveaway. 
• Calibration maintenance: ensures long-term consistency. 

Kenwei’s multihead weighers use premium digital load cells and advanced algorithms designed to keep product giveaway exceptionally low. 

4. Match the Weigher to Your Hygiene and Environmental Standards

Different environments impose different equipment requirements. Consider: 

• Material selection: 304/316 stainless steel for food-grade or pharmaceutical use. 
• Protection levels: IP65 or IP67 for dusty, wet, or frozen working conditions. 
• Cleaning convenience: tool-less design and modular components reduce downtime. 

Kenwei’s structural designs prioritize sanitation, durability, and easy maintenance across food, chemical, and pharmaceutical sectors. 

5. Ensure Smooth Integration With the Whole Packaging Line

A multihead weigher is just one link in a complete packaging system. Proper integration ensures uninterrupted flow with: 

• VFFS machines 
• Premade pouch systems 
• Conveyors, metal detectors, checkweighers 

Kenwei offers tailored integration services to ensure the weigher synchronizes perfectly with upstream and downstream equipment. 

6. Evaluate Long-Term ROI Instead of Initial

Cost The most cost-effective option is not always the cheapest upfront.

Consider: 

• Energy consumption 
• Spare parts and maintenance costs 
• Savings from reduced product giveaway 

Machine durability and lifespan  Kenwei designs its machines for long-term reliability and stable performance, ensuring a strong return on investment. 

7. Prioritize After-Sales Support and Technical Expertise

Reliable service ensures your production line stays operational. Kenwei provides: 

Global technical support 

On-site installation and commissioning 

Remote diagnostics and troubleshooting 

Operator training for optimal performance 

A solid service network reduces downtime and operational risk. 

8. Conclusion
