Spray Painted & Laser Etched Silicone Rubber Keypad for the Aerospace Industry
The keypad shown here was designed for use in an avionics display application. We were responsible for sourcing the molded silicone keypad which was composed of a translucent 70 ± 5.0 durometer (Shore A) silicone rubber.
The face of the keypad is toned to ensure uniform light transmission for all the graphics, and required the use of our spray painting capabilities. We applied black FED-STD-595 #37038 over white FED-STD-595 #37875, as well as a clear matte polyurethane top-coat which was applied to provide the desired look and feel.
Masking for the painting was fabricated in-house using our plotter/cutter, while the spray painting was performed in our spray booth with fume exhaust, and then cured in our batch oven. The components also received laser etching on our Ytterbium fiber laser.
The finished components measured 6.000" by 6.000", and met tolerances of ± 0.005". To learn more about this project, see the table below or contact us directly.
