Recently Bonfiglioli's area sales manager was contacted by a South East Asian company who needed a leak tester for their BFS production line.
The first machine offered was the PKIs (which is the PKI machine for strip). However even though this machine met their requirements, the company could not afford the kind of financial investment it entailed so the Bonfiglioli LPS was the solution recommended by the sales manager of Bonfiglioli.
Since this BFS product was the first to be launched in their market, they had to validate the line and to launch the product with the approval of the industry's inspectorate. This meant that they needed to enter this competitive market with a product that was also 100% leak tested to ensure product's integrity.
The LPS tests the container by pressure, a card of 5 ampoules is positioned under a testing head of 5 fingers, each of which pushes onto one ampoule. The pressure resulting is measured. The card is then shifted under a second testing head (identical to the first) and the same kind of reading is taken. This process is repeated for a number of times. If a leak is present the air/liquid inside the ampoule will come out slowly under the force applied. If the difference in pressure readings is greater than a specified acceptance the card will be rejected. The LPS detects a leak of up to 90 micron. One must note that this varies on product shape and size, line speed and the number of testing heads.
The company has expressed its satisfaction with its new acquisition and the way Bonfiglioli's sales manager took active part in the purchasing process from beginning to end.
