Painting and Internal Copper EMI Shielding of Box Housing for Medical Industry

Our technical ability to satisfy the toughest finishing requirements brings many clients to Plastisol Products. We painted the plastic molded box housing shown here for a customer in the medical industry. Our challenge was to combine EMI shielding and decorative paint in multiple layers over the entire geometry while achieving a near flawless appearance.

After media blasting to achieve the appropriate pre-coat surface profile, we applied a shielding copper paint, taking extreme precautions not to permit any excessive build up around the edges while also maintaining the non-flat surface geometries on both the interior and exterior. We followed that with a light blue paint layer to provide the desired visual appearance. Since EMI shielding effectiveness is a function of paint thickness and uniformity, it was acutely important for us to develop and maintain strict process parameters. We utilized various test methods, including decay rub and cross hatching, to determine that the coating was effectively bonded to the plastic substrate.

We successfully completed this job with the given time constraints. If you are interested in learning more about this project or the processes we used to produce it, contact us today.
