Loma: Combination checkweighing and metal detecting system

The latest CW3 SlimLine combination Checkweighing and Metal Detecting system from Loma Systems combines state-of-the-art inspection performance with a remarkable 50% packing line space-saving from the metal detector head.

Designed to meet the requirements of food producers large and small, the new slim-line design integrates the CW3 Checkweigher – renowned for its superior performance and accuracy - with Loma’s highly sensitive IQ3+ Metal Detector.

The amalgamation of these two powerful technologies within such a compact unit allows suppliers to meet the quality assurance mandates of the most demanding retailers whilst enjoying a competitive cost of ownership – due to cost savings of up to 15% when compared to the purchase of two individual units, and the flexibility to achieve increased productivity.

Today’s high speed packing lines, along with their associated on-line devices, mean that floor space is all too often at a premium. Production managers, faced with changing market demands, need the flexibility to refine the factory layout in order to achieve maximum productivity.

The new SlimLine inspection unit not only delivers a reduced footprint savings, but can be relocated quickly and easily to meet fresh manufacturing requirements. This space-saving generates opportunities for increased line automation, greater productivity and higher levels of operator safety.  

Effective quality control through proven performance
Despite its compact size, Loma’s new inspection unit is big on performance and reliability. The IQ3+ metal detector uses variable frequency technology which means that products can be automatically calibrated in a matter of seconds and frequency data for many different products can be stored for fast and easy set-up. Contaminated products are rejected by means of a pusher mechanism, diverter or air-blast.

Sharing the same touch-screen interface, the CW3 Checkweigher identifies over- and under-weight packs, and an independent rejection function means that off-weight product content can be reused and repacked.

Readily integrated into the factory management system, the combination inspection unit ensures that QA standards are achieved and consistently maintained. Effective data transfer ensures that production management receives accurate quality reports, and that there’s a clear audit trail for product traceability 

Inspection solutions that keep on working
As you’d expect from a Loma machine, the CW3 SlimLine Combination Checkweigher and Metal Detector is designed to survive, offering prodigious levels of reliability and system performance. Built with heavy-duty conveyor components – incorporating quick-change belts - and high quality electronics, it’s designed for tough industrial environments. With its brushed 304 stainless steel housing, the unit meets IP65 wash-down specifications.


The combination of two innovative machines in one slim-line space-saving unit provides a cost-effective inspection solution for any food processor looking for increased productivity and flexibility from its packing operations.
