Lid and base seals
Perimeter seals for handheld and wall-mounted enclosures.
Electronics-grade manufacturing · Enclosure seals
Electronics enclosure seals.
The seal around an electronics enclosure is often the last part designed and the first to cause problems. Getting it right early saves redesigns later.
The detail
Seals that suit plastic housings
Plastic enclosures flex between screws. A seal that's too firm leaves gaps between fixings; one that's too soft takes a set and stops sealing after a few seasons.
We look at screw spacing, wall stiffness and the closing force your fixings can apply, then propose a seal section and hardness that keeps contact all the way round.
Where it fits
Common enclosure seals
Display and bezel seals
Seals around screens and windows.
Port and button seals
Seals around connectors, buttons and indicators.

Questions
What people usually ask.
Can you help us pass an ingress test?
We can design and supply the seal and help diagnose failures. The test itself is usually done by you or a test house.
Should the seal be overmoulded onto the housing?
At higher volumes it can remove an assembly step. See substrate overmoulding.
