It gets both expensive and time consuming with production down time that is an effect of unwanted metal contaminants in the production. Planer blades get ruined, iron bars gets stuck in the chipper, belts on conveyors gets destroyed etc. One can reduce down time on critical machines by using metal detectors in the process that also results in a short payback on the investment itself.
We have the by far widest range when it comes to metal detectors to be able to fit all types of applications.
