Is it possible to mask certain areas on parts to prevent them from being coated?

PVD is a line-of-sight process; therefore, it is possible to mask areas in order to prevent them from receiving coating deposits. When custom masking fixtures are required, our in-house machine shop is able to respond quickly in order to meet the customer’s needs. The CVD process uses various gases during the coating process; therefore, coating will deposit anywhere the gas can contact the substrate. Due to the nature of this process, post-coating grinding of critical dimensions using a diamond wheel is usually a better option. The TD process uses a molten salt bath during the coating process; therefore, coating will deposit anywhere the liquid can contact the substrate. Due to the nature of this process, post-coating grinding of critical dimensions using a diamond wheel is usually a better option. Please contact us regarding feasibility and costs related to masking your particular application.
