Who to contact? Need help finding custom rubber molding manufacturer

Hi,
I am having really hard time finding a rubber injection molding manufacturer who could make these tubes for us but the trick is they can't have a parting line outside and need to be relatively long, i.e. 80mm and 170mm.
If anyone here knows any company that specializes in custom rubber injection molding please PM me. I have already contacted several manufacturers but the problem is length and no parting line.
I will appreciate any leads. Thank you.

Hello Aleksandra,
What is the length, dia and thickness of the tube?

Suhas

Hello Aleksandra.
I agree with Suhas ,we do not know the size and thickness of the tube ,so we do not know whether it can be or not !

Depending on quantity and size, sounds to me like extrusion would be more what you're looking for. No parting line isn't going to happen

Extrusion???? Maybe...

Thank you all for the replies. Extrusion is also a possibility.
The following is the longest and the shortest that I need:
a) ID-2.3mm, Wall thickness: 0.17mm, Length: 80mm, Hardness: 80A Durometer, Material: Viton
b) ID-10.25mm, Wall thickness: 0.7mm, Length: 170mm, Hardness: 60A Durometer, Material: Viton

Can the plastic precision injection molding company help you?
