In automotive electronics, tighter tolerances can feel like the safer choice. More precision. Less risk. Better quality. But that’s not always the case... For injection-moulded housings and covers, the tightest tolerance is not always the best one. If a part functions correctly once assembled, an extremely tight flatness tolerance in the as-moulded state can add complexity without adding value. It can mean more complicated tooling, narrower process windows, increased inspection effort, and even unnecessary cost. The secret is not to just ask: “Is the part perfect immediately after moulding?” But also to ask: “Does the part perform correctly and repeatably in the final assembly?” In our latest blog, Kamil Dionizy, Tooling Manager at Rompa Group, explains why tolerance strategy should be defined around real-world function, assembly behaviour and high-volume production, not theoretical perfection on a drawing.
