Hi all!
I m trying to find some info about how to properly conform aircaft canopys.
I more or less undestand the info about how to heat the plastic and let it drop onto the male mould.
What I don t understand is how to put holes onto the mould to suck the plastic without damaging the plastic.
If the holes are too big you won t be abble to get the final desired shape, the holes would deform the shape, they would suck some plastic onto them, plus you re deforming you re mould with a lot of holes.
On the other hand if the holes are too small they won t suck enough.
Would it be possible to get the desired shape without using a vacuum pump but only with heating the plastic and letting it drop?
If someone has succesfully built a canopy with a bubble shape could you please post some photos of the holed male mould?
Thanks in advance for your help!
