FAQ

(1) What is the purpose of an Aluminum Tube Internal Coating Continuity Tester?

The instrument is used to detect whether the internal coating of aluminum tubes is continuous and free from defects. It identifies problems such as pinholes, cracks, and incomplete coating coverage, helping manufacturers ensure packaging safety and prevent corrosion or interaction between aluminum and filling materials.

(2) What types of aluminum tubes can be tested?

The tester is suitable for aluminum tubes with diameters from 8 mm to 45 mm and lengths from 35 mm to 250 mm. It is commonly used for pharmaceutical ointment tubes, cosmetic packaging tubes, chemical containers, and other aluminum tube products requiring internal protective coatings.

(3) Why is internal coating continuity important for aluminum tubes?

The internal coating acts as a protective barrier between aluminum and the packaged product. If coating defects exist, aluminum corrosion, contamination, or product quality problems may occur. Continuity testing helps manufacturers identify defective products before shipment.

(4) How does the tester detect coating defects?

The instrument uses an electrical detection method. A controlled voltage is applied to the aluminum tube, and leakage current is measured. A continuous coating prevents current flow, while coating defects allow current leakage, enabling the instrument to identify defective areas.
