Smooth inner surfaces and 100% same geometry of runners + flanges and injector ports. How is better to make thick walled flanges ? More precisely, how not to sacrifice one of the parties? It could be easy just to make 2 piece mould…
I think about bladders ,but how to make it precisely for this closed chamber ?
Just use Aquacore.

Perfect info. Thank you!Is there any analogues on the market, or only to the manufacturer?
Please give additional info if you already made some projects with…Is is smooth as the mould is ? What about its price(can not open their price list) ?
And I still have to find the best way ,how to make the mould in flanges zones : to make both sides precision fat as it is and smooth where it have to be .
It is not a very easy stuff to work with: some time ago it was sold as two kind of powders (Aquacore and Aquapour). once formed in a suitable mould, they had to be force dried into an oven to eliminate any kind of moisture inside it: a lot of heat and time is requested. Then you have to spray finishing product on the surface to achieve de smooth surface you need. Now it is available also in block form, to be milled in a cnc machine up to exact shape an ready to use. It is used in F1 very often. It is expensive.
THank you. Do you maybe have more advises about this mould?
Used the material mentioned several years ago and to be totally honest unless its radically improved its xxxx
Heavy,brittle and hard to remove once cooked
You don’t say what system your using but if it was me would go prepreg all the way,this item is in fact similar to parts we are making for a F1 team at the moment
In a previous reply it was said that the quoted material was used in F1 ! No it isn’t !!! Now every thing in F1 is 3D printed.
There is a saying “you copy a Ali part in carbon your just making black aluminum” You design your composite part to do the same job as an Ali part but you work to the properties of your material not copy what the Ali foundry did.
You don’t need a mould as you want your A surface on the inside
4 separate pipes 3D printed plus your main body,all printed and with rebates/dowls so you can join the pipes to the body.you also need a jig frame so you can alone and ensure they are all in the right spot in relation to each other.
Laminate ,bag and cure on low temp cure.
Once cure cook at 140 and your 3D goes like marsh mallow and can be removed from the cured pipes/body
The mounting flanges and strengthening rib can all be seperate mouldings that are glued on after
You can make parts with double a surface (that’s what we are going at the moment)but that requires external moulds,3D parts printed hollow and for you to do internal bagging
THank you for this answer . Really interesting. U inderstand all that you told,but still can not find the best method to produce this flange area with propec exact hose/runner positioning. I have to make it +/- 0.2mm x/y. only one idea : fill the mould in that zone and push prepreg layers with another part of mould. I’d be happy to see some moulds made for same/close to application.
Only flanges have to be 2 side surfaced…
