NexGen Rotary Leak Testers for Empty Plastic Containers

ALPS Inspection offers a full range of Rotary leak test machines for empty plastic containers, with standard configurations from 4 to 30 test stations, and speeds up to 1,200 containers per minute, CPM, (72,000 containers per hour, CPH).

The leak test machine's control system features the ALPS Leak Test Controller, LTC. Test heads on each station use either pressure decay or vacuum decay leak testing to identify defects.

The LTC uses a modular concept incorporating the test electronics, probe, cylinder, manifold and valves in a single quick-connect assembly that can be changed out on the leak test machine in less than 30 seconds. All station specific test data is available for review through the standard color touch screen interface.

The NexGen Rotary leak test machine includes significant advancements in changeover capability. Mechanical changeover is quick and repeatable, requiring no tools or adjustments, and takes 10-15 minutes in total. Each change parts tooling component on the leak test machine can only be mounted in the correct position and timing, using quick-lock attachments.
