Metal components produced for food, beverages, packaging and pharma industries must comply with challenging surface finishing standards. Those surfaces should be ultra-smooth, precision finishing, thus avoiding areas for bacteria grow.
The main features of a perfect sanitary surface include pathogen and corrosion-resistant surfaces, cleanability and resistance to product adhesion to prevent cross-contamination.
Several trade associations and non-governmental organizations, like the American Meat Institute (AMI) and European Hygienic Engineering Design Group (EHEDG), recommend a maximum roughness rating of 0.8 micrometers for stainless steel surfaces in food processing facilities.
The American Society of Mechanical Engineers – Bioprocessing Equipment (ASME BPE) is one body that provides guidance and recommendations to the pharmaceutical industry about surfaces with a standard of 0.5 micrometers.
DLyte’s dry electropolishing delivers mirror finishing surfaces below 0.02 micrometers in the most common metal alloys in the food, beverages, packaging and pharma industries.
The technology achieves superior results than any other surface finishing method in terms of roughness values, cleanability, corrosion resistance, time of process and cost per piece.
