At both Toyo locations we have full inspection departments that employ state of the art CMM equipment to ensure reliability. When we receive new items to manufacture we employ a stringent first article inspection process to validate our programming and processes are in compliance with your requirements. The data generated from our inspection department is recorded and saved to ensure, that with the raw material data from Japan, we have full tracebility for your parts. This is an invaluable service that can be critical when doing any failure analysis and serves to provide a high level of confidence to our customers. We also utilize a vision machine that can offer even more data for features that we might otherwise struggle to measure. When using Toyo Tanso parts you can be assured you are using the most reliable, highest quality parts the graphite industry can provide.
