fibres are compounded into the plastic, the downstream detection of smaller particles is not always reliable. In the food processing industry a large amount of
stainless steel - and to an increasing extent plastics as well - is used in the manufacture of containers, moulds, housings, scrapers and other parts. These components do not always come into direct contact with foodstuffs, but when worn or damaged through typical manufactur- ing operations may contaminate the food with fragments and particles of various sizes. This problem has increased industry demand for all plastic parts that come into contact with food directly or indirectly to be detectable and compliant with food industry standards and specifications. Through a combination of soft-mag-
netic components with impact-resistant polymers, Lehvoss says that it has succeeded in producing a range of compounds that are reliably detectable by current food processing industry detection methods. The presence of fragments or particles of injection moulded, extruded
and otherwise fabricated plastic parts can be observed through metal or x-ray detection systems. Contami- nated food or parts can be apprehended and reliably rejected, even when the foreign particles are only millimetres in size. Lehvoss says the improved
detectability means that expensive and heavy stainless steel and other metals can be reliably substituted by plastic materials, with the further advantage of lower energy consumption through weight reduction in the production chain. Furthermore, the company says that the materials are easy to
process, the additives are well dispersed, and the moulded parts have a good surface finish. Colouring is also possible, which is important as it provides a further means of identification through colour
coding according to food type. The Luvocom Detectables product line is available in many thermoplastic polymers tailored to meet the engineering require-
