What Is a Multihead Weigher and How Does Combination Weighing Work?

In modern automatic packaging systems, weighing accuracy and production efficiency are critical factors for manufacturers. A Multihead Weigher is an advanced Automatic Weighing Machine that uses multiple weighing heads and intelligent combination algorithms to achieve fast and precise weighing.

This technology is widely used in food, agricultural products, and industrial applications, helping companies reduce material waste and improve packaging efficiency.

What Is a Multihead Weigher?

A Multihead Weigher is an automatic weighing system that consists of multiple weighing hoppers controlled by a high-speed computer.

Each hopper independently measures the product weight, and the system calculates the best combination of different hoppers to reach the target weight.

Compared with traditional weighing equipment, a multihead weigher offers:

• High weighing accuracy
• Fast operating speed
• Reduced product giveaway
• Stable automatic production

It is commonly integrated with packaging machines to create a complete automatic weighing and packing solution.

How Does Combination Weighing Work?

The core technology of a Combination Weigher is the intelligent combination calculation algorithm.

1. Product Feeding

 Products are evenly distributed into multiple weighing hoppers through the feeding system.

2. Weight Measurement

 Each hopper measures the product weight independently and sends data to the control system.

3. Combination Calculation

 The computer analyzes different weight combinations and selects the closest combination to the target weight.

4. Product Discharge

 The selected hoppers open simultaneously and release the products into the packaging system.

This method allows the machine to achieve high speed while maintaining excellent weighing accuracy.

How to Choose the Number of Weighing Heads?

Multihead weighers are available with different configurations, such as 10 heads, 12 heads, 14 heads, and 16 heads.

The number of heads affects weighing speed and accuracy.

A 14 Head Multihead Weigher is one of the most popular choices for automatic packaging lines because it provides a good balance between:

• Accuracy
• Speed
• Cost efficiency
• Application flexibility

More weighing heads provide more possible combinations, which can improve weighing performance for different products.

Applications of Multihead Weighers

A multihead weighing machine can handle a wide range of products, including:

• Food Industry
• Snacks
• Nuts
• Candy
• Cookies
• Frozen food
• Agricultural Products
• Rice
• Seeds
• Beans
• Dried fruits
• Industrial Products
• Plastic parts
• Small hardware components

With different hopper designs and feeding systems, the machine can be customized for different material characteristics.

Why Choose an Automatic Weighing Machine?

An advanced Automatic Weighing Machine helps manufacturers improve production efficiency by:

• Reducing manual operation
• Increasing weighing consistency
• Minimizing product waste
• Supporting high-speed packaging

For modern production lines, automatic weighing technology has become an essential solution for improving automation levels.

Conclusion

A Multihead Weigher uses multiple weighing heads and intelligent combination weighing technology to achieve fast and accurate product measurement.

With advantages such as high precision, flexible configuration, and wide applications, solutions like the 14 Head Multihead Weigher and Combination Weigher are widely used in modern automatic packaging systems.

Choosing the right automatic weighing solution can help manufacturers improve efficiency and reduce production costs.
