Case Study: Metal Detectable Gaskets

Metal Detectable Gaskets

Metal detectable silicone rubber gaskets contain additives which make them visible to metal detector scanning equipment. This ensures that any rubber contamination within the product can quickly and easily be identified. Silicone also displays excellent heat resistance and is FDA approved for use in food contact applications.


A UK based snack food manufacturer had an issue with an original, OEM supplied gasket. The gasket, manufactured out of a blue foam, had broken down over time and contaminated some of their product. This resulted in the scrappage of a substantial amount of product as the location of the contamination couldn’t be determined.

The Solution

PAR visited site and suggested the replacement of all foam gaskets with metal detectable silicone. By taking a sample of the original gasket we were able to trace the exact profile using our in-house digitising facilities. This was then precision cut at our Preston branch using our CNC profile cutting capabilities. Replacing the original foam with metal detectable silicone ensures any future contamination is quickly found and removed from the production line.
