If the vacuum is on during the cure, what stops the resin from flowing out of the part and into the pump?

can I just thin tube silicone with white spirit and let it cure? seems easier for one off projects than buying a special system.
I want to apply as fiberglass technician
I love the process
I dont realy get how the vacuum is made. Where is the connection to the pump?
Hi, is it compatible with epoxy prepreg?
I am wondered how vacuum outlet is connected because that part is missed in the video. Resin inlet is well described but how which way vacuum is pumped out ?
Lame. No explanation.

Me 2 seconds into seeing the mold: "It's a Subaru!"
Beautiful ! And thanks for showing something else than thick chopped strand mat !
Could this be used on say a 20 ft boat mould or a larger ocean type Kayak ! and would it be cost effective to do so ?
I realize I am kind of randomly asking but do anybody know of a good place to watch newly released movies online ?
@Sean Gunner i use Flixzone. You can find it by googling :)
@Jaxon Clay Yea, I've been using Flixzone for since march myself =)
@Jaxon Clay Thank you, signed up and it seems to work :) I appreciate it!
@Sean Gunner glad I could help xD
While applying gel coat, a respirator should be worn. How many parts will that bag make?
It is epoxy gelcoat and epoxy is not toxic.
how do you prevent the laminate from becoming too dry while curing under full vacuum?
It doesn't happen. There's no bleeder, so when resin feed is clamped, only excess resin makes it to the catch pot.
Seems easy to make it. Where is the hole connect to the vacuum pump?
That's a good question! Normally there would be a vacuum connection through the silicone bag right over the peripheral vacuum channel. In this instance there is a connection through the lower half of the mould (in line with the vacuum channel) You can just see it in the first part of the video when the lower mould is empty.
@@siliconecomposites1890 Cool! Thanks for teaching.
interesting! why flow mesh is not necessary? best regards!
Hi- You can use flow mesh in exactly the same way as you would use it in a conventional infusion. In this instance it wasn't necessary as the mould is rather small and the laminate is reasonably permeable.
how many times can you use the silicone bag please? also, can it be brushed on?
Hi Ted, the life expectancy of a silicone bag will depend on the resin being used but we have customers reporting between 250 to 300 cycles with a polyester resin. The general care and handling is also obviously very relevant.
@@Compositeinteg1 Thank you
Where was it used for? By the way: a very interesting process and well documented in the video.
Hi, This mould was made just as a technical demonstration but the process is used in a variety of different applications to produce composite mouldings (i.e. marine, automotive, architectural etc) Have a look at our website www.siliconecomposites.com
OK, thanks!

3:51 what's the effect of 'intensifiers'? Is this to apply more clamping force in certain areas under vacuum?
Hi Paul, We filled these small detailed ares with solid silicone so that they are more likely to stay in shape and to press the fibre into the correct position under vacuum.
Ow man, what a nice job! Loved it!
Thanks Luiz- we're glad you enjoyed it!
