How to choose Maotong Inspecting equipment
Maotong (usually referring to Jinan Maotong Inspection Equipment Co., Ltd.)'s air leakage detection equipment is widely used in the food and beverage packaging industry. It primarily uses squeeze detection technology and online automated testing to ensure packaging sealing.
The following table summarizes the core information of several representative leak detection devices from Maotong for your quick understanding: .
Device Model/Name | Main Detection Target | Core Detection Technology | Key Performance Indicators | Key Features
|
Bagged Product Leak Detection Device (MT-YLDJ-03) | Bread, puffed foods, and other bagged products | Flexible extrusion belt + pressure sensor | Inspection speed up to 400 bags/minute | Pre-extrusion function: Long-distance extrusion fully releases pressure from products with minor leaks, ensuring more accurate detection |
PET Bottle Cap Liquid Level Inkjet Inspection Equipment | Beverage bottles, medicine bottles, and other PET bottles | Optical/ultrasonic liquid level detection, cap seal inspection, and OCR code recognition | Liquid level detection accuracy up to 1mm | Multi-functional integration: Comprehensively inspects capping, liquid level, and code quality in one go
|
Online Can/PE Product Inspection Machine | Rigid packaging containers such as cans and PE bottles | Non-contact scanning (presumably optical or pressure sensing) | Rejection rate ≥99% accuracy, with an inspection speed of up to 1,200 cans per minute | High-speed and high-precision, it's suitable for assembly lines in the beverage and chemical industries.

Technical Principles and Advantages
The core concept of Maotong's equipment is to determine the sealability of packaging by detecting minute changes in internal pressure. Its technical advantages are primarily reflected in the following:
Dynamic Continuous Inspection: The equipment uses a flexible squeeze belt (for bagged products) or non-contact scanning (for rigid packaging) to continuously and evenly squeeze or scan the product while it's being conveyed through the production line. This process does not block or hold the product, ensuring high inspection efficiency.
High-Precision Sensing and Intelligent Processing: The equipment integrates highly sensitive pressure sensors and optical sensors. The collected data is analyzed in real time by a DSP (digital signal processor) or PLC (programmable logic controller), accurately distinguishing between qualified and unqualified products and effectively reducing false positives.
Automated Rejection and Data Management: Upon detecting a defective product, such as a leak, the system immediately triggers an automatic impactor or pneumatic pusher to remove it from the production line. Some high-end equipment also features data statistics and can generate test reports to assist users with quality traceability and production line optimization.
Main Application Scenarios
Maotong air leak detection equipment is widely used in industries with stringent requirements for packaging tightness:
Food Industry: For example, testing seals for air leaks in bagged snacks like bread and puffed foods.
Beverage Industry: Testing the seals, liquid levels, and inkjet printing quality of PET bottles and cans.
Pharmaceutical and Daily Chemical Industry: Ensuring the tightness of pharmaceutical bottle caps, the accuracy of liquid fill volumes, and the integrity of daily chemical product packaging.
How to Choose
When choosing the right equipment, you can focus on the following:
Packaging Type: Select the appropriate equipment model based on whether your product is bagged, bottled, or canned.
Production Speed: Ensure the equipment's inspection speed (e.g., 400 bags or 1,200 cans per minute) matches your production line's pace.
Specific Testing Requirements: Determine whether you require a single air leak detector or a device that integrates multiple functions such as liquid level and inkjet printing. I hope this information helps you gain a comprehensive understanding of Maotong's air leak detection equipment. If you can provide more specific product types or production scenarios, perhaps I can provide a more targeted analysis.
