General Measure Technology Co. Ltd. (China) - Improving Food Safety and Weight Control with the General Measure CW-3K Checkweigher with Metal Detector

Customer Background

A food and beverage manufacturer producing liquid products in both bottles and flexible bags needed to strengthen quality control at the end of its packaging line. The company faced increasing requirements for:

• Accurate weight verification
• Reliable metal contamination detection
• Compliance with food safety standards
• Efficient use of limited production floor space

The customer wanted a single inspection solution that could perform both weight checking and metal detection without adding multiple standalone systems to the line.

Challenge

The manufacturer encountered several operational challenges:

1. Product Giveaway and Underfilled Packages

Variations in the filling process occasionally resulted in overweight or underweight products, leading to product giveaway, customer complaints, and quality risks.

2. Food Safety Concerns

The company needed to ensure that any metal contaminants introduced during processing or packaging could be detected before products reached consumers.

3. Limited Installation Space

The existing production line had limited room for additional equipment, making it difficult to install separate checkweighing and metal detection systems.

4. High-Speed Production Requirements

The inspection solution had to keep pace with continuous production while maintaining stable accuracy.

Solution

General Measure supplied the CW-3K Checkweigher with Metal Detector, an integrated inspection system combining dynamic weighing and metal detection in one compact platform.

Key Features

• Integrated checkweighing and metal detection
• Weighing range: 0.3–3 kg
• Best accuracy: ±0.5 g
• Throughput up to 150 pcs/min
• Compact footprint for easy line integration
• Suitable for both liquid bag and liquid bottle production lines
• Automatic rejection of non-conforming products

Application

Liquid Bag Production Line

The CW-3K was installed after the filling and sealing process to inspect packaged liquid products.

The system:

• Verifies that each package meets weight specifications
• Detects metal contaminants before shipment
• Automatically rejects defective products
• Provides continuous quality monitoring without slowing production

Liquid Bottle Production Line

For bottled products, the CW-3K performs the same dual inspection process:

• Dynamic weight verification
• Metal contamination detection
• Automatic removal of non-compliant products
• Stable operation despite varying product sizes and packaging formats

Results

Enhanced Product Quality

Every packaged product is inspected for both weight compliance and metal contamination before leaving the production line.

Reduced Product Giveaway

High weighing accuracy helps optimize filling processes and minimize unnecessary overfilling.

Improved Food Safety

Integrated metal detection provides an additional layer of protection against contamination risks.

Space Savings

The 2-in-1 design reduces equipment footprint and simplifies production line layout compared with separate inspection systems.

Increased Operational Efficiency

The customer benefits from automated inspection and rejection, reducing manual quality checks and improving production consistency.

Conclusion

The General Measure CW-3K Checkweigher with Metal Detector provides food and beverage manufacturers with a compact, efficient, and reliable solution for end-of-line quality inspection. By combining weight control and metal detection into a single system, the customer achieved higher product quality, stronger food safety protection, and improved production efficiency while minimizing equipment footprint.
