High-Speed Leak Tester | Inline Air Tightness Inspection, Real-Time Alarm & Automatic Rejection of Defective Bottles

2026-10-15

Pinholes and tiny cracks on blow-molded bottles will cause liquid or gas leakage, resulting in material waste and customer complaints after filling. Xinzheng Machinery high-speed leak tester is designed for inline integration with blow molding lines to perform air tightness inspection on hollow containers. It completes automatic testing and sorting to guarantee your packaging quality.

Product Functions

The machine conducts air tightness testing for hollow containers of specified sizes. After inspection, qualified and defective bottles are separated automatically. When leaky containers are detected at the test station, the system triggers an alarm and rejects defective bottles instantly to separate faulty products from good ones, preventing leaking bottles from flowing into subsequent processes.

Machine Features

High sensitivity: Detects tiny gas or liquid leakage on bottle walls with high precision, capable of identifying micro defects
User-friendly operation: Requires no complicated setup or professional technical knowledge, suitable for various factory environments and operators
Real-time inline inspection: Continuous online detection; leaky containers are identified and rejected automatically
High speed & space-saving: Fast running speed, fewer test heads, convenient adjustment via slide rail structure, compact footprint
Vacuum suction conveying: Slide rail structure equipped with vacuum bottle transfer, stable bottle handling for multiple hollow blow-molded containers

Applications

Easily integrated downstream of extrusion blow molding machines for online sealing inspection of detergent bottles, oil cans, food jars, chemical packaging containers and other hollow blow molded products.
