ALPS NexGen Rotary Leak Inspection Systems

The NexGen Rotary Leak Inspection System from US company ALPS (Air Logic Power Systems) is suitable for plastic bottle blow moulding, metal container, composite container and dispensing closure manufacturing companies.

The system, using encoder-based timing and speed compensation technology, performs functional tests on plastic containers and other products to ensure they seal and can hold pressure. It eliminates issues particularly related to current generation, lightweight bottles that use recycled materials and where there is an increased probability of ‘micro-leaks’.

The system seals and pressurises every container with a test probe - performing a decay timed pressure test - and can test from hundreds of milliseconds to several seconds on the container or closure, depending on the level of testing required. It has a detection range from 0.1 mm diameter and detects defects (such as: gate pinholes and cracks; laser coding holes; contamination holes; thin wall holes; short shots; seal surface nicks; malformed bottles or containers; and weak bottle shoulders or base) by using the top-load test option.

The machine is available in configurations from 4 to 30 heads, designed to meet specific speed and sensitivity requirements, and has a speed of up to 60,000 bottles/h. It is suitable for lines ranging from 50-1000 cartons/min and is currently being used on FMCG production lines worldwide for food, beverage, household cleaners and automotive products, etc.

Product changeover takes as little as 10 minutes, with quick-lock  no-tool-change parts and they have integrated air blow-off ejectors and standard reject verification.
