Bottle Leak Tester For Plastic HDPE And PET Containers - Automatic Inline Leak Detector

This equipment is a fully automatic, high-precision industrial airtightness and leak detection system; It features an integrated aluminum extrusion frame design and is an in-line, fully automatic airtightness testing system developed specifically for products such as plastic bottles, plastic containers, and hollow plastic parts. It integrates a PLC touchscreen control system, precision air pressure sensor modules, a pneumatic downward-pressing sealing mechanism, and a conveyor line, enabling the automated completion of the entire process—from workpiece loading and positioning, sealing, constant-pressure leak testing, to the sorting of good and reject sorting. It is widely used for detecting water and air leakage defects in products such as personal care bottles, food packaging, bathroom plastic components, and new energy enclosures. By employing the differential pressure method or direct pressure method, it performs rapid, non-destructive seal performance testing to effectively ensure product quality before shipment.

The system employs a pneumatic leak detection method: After the detection head is pressed firmly against the sealed workpiece, compressed air at a preset pressure is introduced into the sealed cavity. The system maintains a constant pressure for a set period, while high-precision sensors monitor changes in the cavity pressure in real time. If the product has micro-pores or cracks causing air leakage, the pressure inside the cavity will drop significantly. The equipment immediately classifies the product as defective and issues an audible and visual alert, while products are automatically released. This enables rapid, non-destructive leak detection without damaging the appearance of the workpiece.

• Fully Automatic In-Line Inspection
  Integrated with conveyor lines for continuous operation, eliminating the need for manual handling of workpieces. Loading, inspection, and sorting are fully automated, significantly reducing labor costs and making it ideal for high-volume production on assembly lines.
• Dual-Station Synchronous Inspection
  Two inspection heads operate simultaneously, allowing two products to be inspected in a single pass. This doubles inspection efficiency and increases production capacity, making it suitable for medium- to high-speed blow molding and injection molding production lines.
• High-Precision, Stable Leak Detection
  Dual pressure gauges monitor inflation and inspection pressures in real time. Pressure, hold time, and leak thresholds are digitally adjustable, enabling precise detection of even the smallest leaks. Inspection results are stable, with an extremely low false-positive rate.
• Convenient Changeovers and High Versatility
  The aluminum profile modular structure allows for manual adjustment of the downward pressure height and the spacing between inspection stations. By simply replacing the sealing fixtures, the system can accommodate plastic bottles and hollow containers of varying heights and diameters, making changeovers and setup straightforward.
• Intelligent Data Management
  The touchscreen displays the number of good and defective products as well as leak curves in real time. Production and testing data are automatically stored and can be exported for traceability, facilitating quality control.
• Durable and Easy to Maintain
  Standardized pneumatic components and an aluminum profile frame ensure that spare parts are interchangeable and easy to source. The clear layout of piping simplifies daily cleaning and maintenance, making the system suitable for 24-hour continuous production in a factory setting.

The overall product quality has traceability, and the product quality warranty period is 1 year, calculated from the date of equipment acceptance.

Free maintenance during the warranty period, with corresponding travel and material costs charged for after-sales service exceeding the warranty period.
