Embossed vs. engraved text for outdoor molded parts
T
Hi there, I need to add a part number and recycling symbol on the surface of molded parts in PP GF20 for outdoor use. I initially planned to use engraved text for aesthetic reasons, but I’m concerned about visibility and tool wear over long production runs. Would embossed text (raised on the part) be a better option here in terms of durability and legibility? The surface finish is light matte, and cycle times are tight, so I’m also considering mold complexity.
