Leak Testing of Metal Packaging

Metal packaging, especially aerosol cans, require robust and sensitive inspection systems in combination with reliable product handling. Our product lines for metal package testing profit from long experience and ongoing developments.

R AE

Pressurized aerosol cans are under strict guidelines related to leak testing. If any aerosol dispenser shows evidence of a leakag rate equal to or greater than 3.3 × 10-2 mbar.l.s-1 at the test pressure, distortion or other defects, it will be rejected. Our aerosol can tester complies with these regulations.

Highly accurate and reproducible results

Robust inspection system

Fast format changeover

The R AE is a leak testing system for empty aerosol cans which fulfills current ADR guidelines. An in feed star wheel places the cans onto the continuous moving carrousel. The cans are sealed by a clamping device inside the test chamber. This clamping device allows the testing of the can in a “hanging” position, thereby opening up possible leaks in the seam.

The R AE can tests up to 500 cans per minute. Due to its design it can be integrated into an existing production line. Automatic software features fully automatically compensate any outside influences, such as temperature variations. The high test pressure inside the cans allows the system to detect leak rates of 3.2 x 10-2 mbar.l.s-1 on all can formats assuring that the UN specifications on the Hot Water Bath alternative are met.
