Then, either consult the companies' websites or, in my opinion, call them directly to find out if they do this type of service.
You can also try calling the company below that distributes Moplen. Maybe a nice person there will be able to inform you and direct you to a plastics manufacturer who is used to making Moplen objects.
Its good thing because I received yesterday the KD FEDDERSEN dealer who is also a Lyondellbasell dealer (manufacturer of the moplen brand) unless another brand does the trick? Can I inquire if they do extrusion grades and who they sell it to if you want?
Above all, I had the opportunity to work with the company Rhonalpex, which does extrusion and therefore pvc without any problem.
If necessary, I pass on the sales contact from them.
In fact I advise you to send a request to a transformer with if possible 3d and 2d, specifications (solvent resistance, mechanical, bending, ect...), annual order volumes and number of parts/orders.
As in your case, the inner diameter is not functional for you except for mechanical resistance I guess.
This kind of remark allows him to advise you in the design related to the process.
In the end, he will give you a quote that you can compare with others.
As for the brand, he will choose himself according to his internal standards and specifications.
Being a processor, I advise you to listen to his choice because in the end he is the one who transforms it and therefore guarantees the quality of your product.
There are equivalents in all brands (a technyl a218 is equivalent to a nilamid a2 H7 G6 for polyamides 6-6 for example).
I'll transfer the contact details to you
Don't hesitate if you need information, it's a milieu that I know well and if I can be useful it's with pleasure.
