Laser engrave and then chemfilm or vice versa

May 28, 2013

Q. We have a part made out of 7075-T7351 which needs to be laser engraved and also chem-filmed. We are not sure in which order to do these processes. Laser engrave and then chemfilm or vice versa. Does anyone have any experience with this type of requirement?

Thanks

A. Laser engrave first, then chem film. Otherwise the laser engraving will remove the chem film where it's engraved.
