+xHi I have been looking at this Air Box and trying to figure out how I can Vaccum Bag ??? to me looks impossible, so any help appreciated, Regards DM Hi There, Actually, I think you might be overthinking it. Unless there's something I'm missing - I'm assuming that the bottom face which we can't see it completely open - The the bag would actually be very simple, it would just need to also be very large (like more than twice the size of the part). I can't see the mould so I don't know if you're planning to envelope bag or tape to the mould flange but the principle would be the same either way. If the bag was large enough you could just feed two 'socks' of bag into the inlet tubes and then would blank off at the mouth of the tubes (again, I can't see the mould but I assume the mould too blanks off at the mouth of these inlet tubes). As Steve has posted we also don't know what the rectangle is but I'm assuming it's just a cuboid shaped recess which is fully closed off, in which case you could just bag around this using the huge excesses of bag I'm suggesting again too. If you were envelope bagging then just imagine an absolutely massive bag with the part and mould inside and the bag sealed all around. When you do this you can picture yourself just stuffing bag into those two inlets (as though you'd fashioned some tube shapes from the big bag and fed them into these inlets) and then and the rest into the main area. I hope this helps but if I've missed something then let me know!

Hi Matt, Thanks, as yet I have not made the Mould ( The Pic I got Online) so just trying to figure out how to go about it, this is just to top part of the air box as the bottom rectangular portion is completely open as the Air Filter sits between the top and bottom portion, also the 2 round tube sections are completely open, and also the ends of the tubes have quite a hefty Flange which is used to bolt to the MAF's ?/ so how would I go about these flanges as well, again I will enclose 2 more pics, and thanks for all your help, I will get to make some CF parts very very soon with your help,Regards DM

Knowing that will probably change how you think about the bagging. As for the flanges, they are quite likely to be separate components that are bonded on afterwards but they don't have to be. I can't really see from the images but you could either make them as separate parts or set up removable barriers on the mould to form these flanges.

+xA bit like this. Hi Steve Thanks, I can see your mould has an opening on top, but is the other end also open like mine?? Regards DM

Regards DM I don't think you need to do it on your part (because I think once you blank off the two tubes in your mould you'll actually have no open ends on your moulding) but if you're struggling to understand how to bag a 'tube' then just think of creating a bag like a torus (donut). Bagging tubes is common practice.

Hi Steve, Thanks, so was the rectangle end of your Mould blanked off for Vacuum bagging and then when released from mould you cut out the rectangle end, is that correct, again Thanks for your help, Regards DM
