Fitting two plastic parts together with no seam is basically impossible unless you are Apple. How's Apple do it? Any tricks aside from very tight tolerances

Fitting two plastic parts together with no seam is basically impossible unless you are Apple.
How's Apple do it? Any tricks aside from very tight tolerances
(eg. Not applicable to all geometries but in 3D printed parts I've leveraged chamfers that bring a mating feature to a "knife" edge to essentially "bite in" to the other surface when I want a tight fit without gaps and without post-processing)
- joezydeco 4y agoI thought I read somewhere that Apple does it by having the Chinese line workers manually try different pairs of parts until they find two that fit precisely.
- namibj 4y agoThe tolerances shouldn't be a problem with some iterative design of the tools so today the parts fit together perfectly when made from same-age molds. It's just a lot of effort you can't afford unless you go through a bunch of tools just due to the lifespan the tools have.
