Looks awesome.
What kind of foam are they using with the IMP technique ?
I could not tell. I think they mixed up the production of different types of bicycles. At the IMP stage you see complete frames being built up. After that you see frames being glued from separate pieces.
Just from looking at the movie, I guess the white foam is an expanding microsphere (Expancel) but I am not sure.
I thought expancel is in powder form??
Yes, but you can use a binder of some sort. They so not show it all in that kind of promotional films…
at min. 1:19 you can see the bladder protuding from the laminate. The foam is rubber covered an than inflated to apply pressure.
Anyone have more specifics on this type of manufacturing? Where to get the expanding foam? How to mold it? What type of bladder? How bladder is put on the outside of foam (of foam is put inside bladder?)
Seems interesting for hollow parts.
If you use the bladder, you don’t need expandable foam.
The bladder is the liquid one. Just splash the mandrel into it a few times until the desired thickness is achieved.
Roberto, any links or suggestions for the liquid bladder that is high temp?
I use the Axson Essil 59 for that purpose.
But any “low” viscosity two parts silicone could work. Just test it.
Thanks Roberto,
I’ll check out that product.
What do you make? Is there any issue with silicone and migration? I need to be able to secondary bond to the finished product.
Thanks
Of course, the use of silicone affects the surface it is in contact with. I usually wrap the silicone with thin release foil.
I make parts in prepreg/autoclave.
Thanks to the MTI hose I’m using infusion too.
