In-line quality control system

MD 2002 Metal detector - CP 812 Weight monitor - RJCT 368/10 Bag rejecter.

Automatic, constant, assured control of all production process stages.


This system is specially designed to carry out meticulous quality control and assure uniform output.
It guarantees the absence of metallic foreign bodies (magnetic and non-magnetic) inside bags (rejecting those which do not conform). What’s more, it allows weighing operations to be performed with top precision, and provides direct generation of production reports.


There are no installation problems. The system is located in-line, downstream of the bagging system.
