Quality control
Combi metal detector and checkweigher
The combi machine is the perfect blend of safety and control: a compact stainless steel unit that combines a conveyor-mounted Fortress metal detector with a dynamic checkweigher, plus a reject system for bags contaminated with metal or outside the weight tolerance. It is built to order, combining detectors from different manufacturers with our own checkweighers, and thanks to in-house manufacturing we can provide custom reject systems and special adaptations.

Why choose it
01
Two checks in one unit
Metal detector and dynamic checkweigher in a single compact machine, with one reject system.
02
Built to order
Each combi is built to the customer's needs, combining detectors from different manufacturers with our checkweighers.
03
Rejects contaminated or off-weight bags
The reject system removes the bag whether it contains metal or its weight is outside the tolerance.
04
Conveyor-mounted Fortress detector
Fortress metal detector head mounted on a conveyor, the best application for packed product.
05
Stainless steel
Compact quality control unit built in stainless steel.
06
Special reject systems and adaptations
Thanks to in-house manufacturing we provide custom reject systems and special adaptations to your line.
In action
How it works
Infeed
The bags arrive from the packaging machine onto the combi's infeed belt, 220 or 330 mm wide.
Metal detection
The Fortress detector head inspects every bag for metal contaminants.
Dynamic weighing
The checkweigher weighs the bag on the move, with an accuracy of ±0.5 to 3 g.
Rejection
Any bag with metal or outside the weight tolerance is removed from the line; the rest continue to case packing.

Frequently asked questions
What is the difference between the CM220 and the CM330?
The belt width and the weighing range. The CM220 has a 220 mm belt and weighs from 10 to 1,000 g at 60 bags per minute; the CM330 has a 330 mm belt and weighs from 10 to 3,000 g at 50 bags per minute.
How accurate is the weight control?
From ±0.5 to 3 g on both models, depending on the product and the line speed.
What happens to a contaminated or off-weight bag?
The reject system removes it from the line, whether the detector finds metal or the weight is outside the tolerance.
Which metal detector does it use?
As standard, a Fortress detector head mounted on the conveyor. Because we build to order, we also combine detectors from other manufacturers with our checkweighers.
Can it be adapted to my line?
Yes. Thanks to in-house manufacturing we provide custom reject systems and special adaptations to integrate the combi into your packaging line.
