How to Select the Right Multihead Weigher for Your Production Line

2025-12-11

Selecting the right multihead weigher is critical for manufacturers aiming to maximize productivity, accuracy, and cost-effectiveness. With numerous options available in the market—ranging from small 10-head models to industrial 32-head systems—choosing a machine that fits your product type, production speed, and operational environment can be challenging. This article provides a detailed guide on how to select the optimal multihead weigher and explains why Guangdong Kenwei Intellectualized Machinery Co., Ltd. is a trusted partner for factories worldwide.

1. Understand Your Product Requirements

The first step in selecting a multihead weigher is analyzing the product characteristics:

Product type: Is it granular, powdery, sticky, fragile, or irregularly shaped?

Size and weight variations: Some products require high precision due to regulatory or brand standards.
Moisture content: Sticky or oily products may require specialized hoppers or anti-stick coatings.
Fragility: Chips, cookies, or puffs need gentle handling to reduce breakage.

A deep understanding of product properties helps determine the appropriate hopper design, vibration system, and weighing algorithm.

2. Determine Production Capacity and Speed

Production speed is another critical factor:

Small-scale operations may need 20–50 packs per minute.
Medium-scale factories typically require 80–150 packs per minute.
High-speed industrial lines may demand 200+ packs per minute.

Multihead weighers come in various configurations (10, 14, 16, 24, 32 heads) to accommodate different capacities. The number of heads affects combination calculation speed, which directly impacts throughput. Kenwei offers a wide range of models suited for low, medium, and high-speed production, ensuring consistent weighing accuracy at all levels.

3. Consider Accuracy and Give-away Reduction

Accurate weighing reduces product giveaway and ensures regulatory compliance. Precision depends on:

Load cell quality: Digital sensors provide better accuracy than analog sensors.
Weighing algorithm: Smart combination algorithms calculate the most optimal distribution of product across heads.
Machine calibration: Regular calibration ensures long-term stability.

Kenwei multihead weighers utilize high-precision digital load cells and intelligent algorithms to minimize material giveaway and maintain tight tolerances.

4. Evaluate Hygiene and Environmental Requirements

Depending on your production environment, hygiene and durability are essential considerations: Stainless steel construction (304 or 316 grade) is necessary for food and pharmaceutical applications.

IP65/IP67 protection ensures dust and water resistance, especially in frozen or wet environments.

Tool-less cleaning and modular components reduce downtime and facilitate routine maintenance.

Kenwei machines are designed with hygiene and waterproofing in mind, making them suitable for food, pharmaceutical, and chemical industries.

5. Integration with Packaging Lines

A multihead weigher rarely operates in isolation. It must seamlessly integrate with other packaging equipment such as: Vertical form-fill-seal (VFFS) machines Premade pouch packaging machines Conveyors, metal detectors, and checkweighers MES/ERP or digital monitoring systems Kenwei provides customized solutions that ensure smooth integration, avoiding bottlenecks and maintaining optimal line efficiency.

6. Budget and Long-term ROI

While cost is an important factor, consider the total cost of ownership rather than just the upfront price: Energy efficiency: Modern multihead weighers consume less power. Maintenance costs: Durable, modular designs reduce downtime and repair expenses. Production savings: Reduced giveaway and higher output increase ROI. Kenwei’s machines are engineered for long-term reliability, providing excellent ROI over years of operation.

7. Technical Support and After-Sales Service

Choosing a reputable manufacturer ensures fast support, spare parts availability, and training for operators. Kenwei provides: Global technical support On-site installation guidance Remote monitoring and troubleshooting Training programs for operational efficiency This service network helps factories maximize uptime and minimize operational risk.
