How is this assembled?

Hello Everyone!

I have been trying to develop a product which requires the assembly of a silicone slit valve in a plastic component.
I purchased a products containing this assembly but I can't seem to figure out how it is done.
The picture below show what I am trying to achieve.

The plastic is one single piece. I was assuming the silicone would be pinched between two snap fitted plastic pieces but it is not the case.
I am assuming that the same principle would apply to the following assembly:
(Please correct me if I'm wrong smile)

Any advice will be helpful.


RE: How is this assembled?

It could be a two-shot moulding where the elastomer material is moulded onto the part. Usually requires an elastomer which bonds to the base material. It might not be silicone in this case, more likely to be a TPE.


Politicians like to panic, they need activity. It is their substitute for achievement.

RE: How is this assembled?

Side question... how is a slit valve any different than a gate valve? Workings of control mechanism?
