Metal detectable products are commonly used in food production environments, where consumables such as modular belting, cable ties and pens have the potential to contaminate the supply chain. If any part of a metal detectable product becomes detached, it will be picked up by an industrial metal detector on the production line – preventing supply chain breakdown and expensive recalls.
Metal detectable fillers are converted into an ultra-fine powder and extruded into a polymer masterbatch. SCOPIC can supply either a masterbatch or a ready-dosed compound, with either a universal carrier or tailored to your base material.
Detection of foreign bodies by a metal detector is influenced by the following factors:
Due to these factors, it is difficult to confirm absolute detection levels for metal detectable compounds and this should always be confirmed on the specific detection equipment under standard operating conditions.
Aperture size of detector
Type and orientation of ‘contaminant’
Type of product running through detector
MANUFACTURING & TESTING
We have in-house extrusion and injection moulding capabilities to allow production of custom masterbatches and compounds, as well as moulded test pieces.
Metal detectability can be checked on a Safeline balanced coil metal detector.
Mechanical testing can be performed on unfilled and detectable compounds to confirm the effect of the additives. Tensile testing as well as impact testing can be undertaken.
MFI levels of compounds can be confirmed on an extrusion plastometer.
UV exposure testing can be carried out if necessary.
