Housing seals
Seals keeping fluids and cleaning agents out of devices.
Medical-grade manufacturing · Medical device seals
Seals inside medical devices keep fluids in, contaminants out and mechanisms working. They're small parts with a lot of responsibility.
The detail
A seal in a device will be scrutinised far more than its size suggests. Material, batch history and any change to either need to be documented and controlled.
We usually mould medical seals in LSR for its clean release and consistency, with compression for low volumes and larger parts.

Rough annual volume, target unit price, and any deadlines. That's enough to work out whether compression, LSR injection or something else is the right tool.
