Challenge: A purchase order was issued for two separate part numbers that required rubber ink stamping of the part number onto the parts. Each part must contain the ink stamped number.
Solution: There are various aerospace marking methods and each method is identified on the part print. Rubber ink stamping tends to be an older, widely accepted method; however, it has challenges in that rubber ink stamping is labor intensive; messy such that smearing is common and affects legibility and quality; and it tends to wear or erode over time.
Result: A recommendation was made to change the blue print to allow for Engraving, as opposed to rubber ink stamp. The recommendation would improve legibility of the part marking; improve thru-put in manufacturing; improve lead-time and reduce cost.
