The LF-PK automatic machine is designed to check containers for defects and is intended to operate in temperature-controlled environments with limited humidity and dust variations. The testing cycle consists of closing the container inside the upper and lower chamber. Inside the chamber created between the outside of the container and the inside of the bells, a vacuum is created by a special pump. A special sensor monitors the depression inside this chamber and, at the end of the cycle, if the depression is within the test parameters, the container is good, if, on the other hand, the depression is outside the parameters, the container is rejected. All machines manufactured by BONFIGLIOLI ENGINEERING S.r.l. comply with machine directives 89/392 EEC and 91/368 EEC with subsequent amendments. The mark affixed to the machine guarantees conformity.

Bonfiglioli Engineering has designed and built this fully automatic machine to check whether sample containers are intact.
