High Precision Linear Empty Plastic Bottle Leak Tester For Oblique Mouth Bottles

Linear Empty Plastic Bottle Leak Tester For Oblique Mouth Bottles

Description

The Linear Empty Plastic Bottle Leak Tester is a flexible and high-efficiency tool that secures the integrity of various plastic packaging containers. Designed for mass-production lines, it can handle containers of diverse shapes and capacities, such as standard water bottles, dairy containers (milk bottles), jerrycans and other plastic containers. It conducts accurate, non-destructive airtightness checks on containers that meet preset standards and are waiting for quality inspection.

The testing process is fully automatic. After leak detection, the system smartly sorts the output according to test results. Qualified products move smoothly to the next step. Importantly, any unit that fails the airtightness test will immediately trigger an alarm at the relevant workstation. What's more, the system automatically removes these unqualified bottles from the production flow. This automatic rejection function ensures strict physical separation between qualified and defective containers, avoids cross-contamination of product batches, and ensures that only leak-free containers proceed to filling or shipping. This process greatly improves production quality control, reduces waste and safeguards operator safety.

Machine Advantage

• Adopting the latest detection system imported from the United States, each workstation is equipped with a dual independent leak detection system. This system features high precision and strong reliability, with an accuracy of up to 0.1mm—fully meeting the strict leak-proof requirements of oblique mouth bottle which are widely used to hold cooking oil, salad dressing, hand sanitizer, and other liquid products that require easy pouring. These daily-use or food-grade products often have characteristics like oiliness or slight viscosity. Most oblique mouth bottles are made of food-grade PET or HDPE material, with a 15-25mm inclined spout (30°-45° angle) for anti-drip pouring and screw-on caps or flip-top lids; the seal between the cap and the inclined spout, the joint of the oblique mouth and the bottle body, and the bottle body blow-molding seams are key leak points—leakage will not only cause liquid spillage and waste, but also lead to oxidation of edible oils or bacterial contamination of hand sanitizers, affecting product quality and consumer experience.
• Storage function: The system can store 6 sets of oblique mouth bottle detection parameters (customizable memory), record the total number of oblique mouth bottle detections, the number of leaky oblique mouth bottles, and set the total detection quantity. When the machine completes the detection of the set number of oblique mouth bottles, it will automatically stop the leak detection process. This ensures standardized, efficient, and targeted inspection of batch oblique mouth bottles—in line with the daily chemical and food oil industries’ needs for adapting to diverse product specifications while maintaining strict packaging quality control.
• Stability testing: The equipment adopts German Siemens PLC control, American Motorola detection board, and FESTO solenoid valve control. Its industry-recognized leading stability can reach over 100,000 hours, providing long-term and stable leak detection support for oblique mouth bottle production lines. For these lines, continuous and reliable equipment operation is crucial: it avoids production interruptions that delay the supply of daily-use and food liquid products, and prevents unqualified leaky bottles from entering the market—thus reducing after-sales complaints caused by seal failure of oblique mouth bottle packaging and safeguarding the brand reputation of daily chemical and food oil enterprises.
