Hello

guys im thinking 2 days how to stick flanges to these door panels as hot glue falling of easy .. hm any advise? as i always used this way. i can use glue that used for pva flanges but it melts a little both parts and that not good at all any advise?


Parts been sanded to perfect straight finish. now need flanges somehow to attach then resin infusion. ordering on monday from easycomposites i hope for more things in 1 order they give me better price as last gc 50 was pretty nice deal.

hmm use flat surface, thin plywood or cardboard?
mount door panel to foam blocks on the board
you could use clay to support the edging material and get it up to the edge of the door panel.
you will want the door panel mounted and somewhat fixed and immobile on the board.
be mindful of making any edges that can mechanically lock your tooling gelcoat.
and use the usual methods for mold release preparations.
use foam blocks to fill space near the holes and then use clay to fill in the gaps so your panel is sealed and completely
filled in. i assume your panels are like most door trim panels and are rough or gross and no tape will hold to fill the holes. i would not use tape for the application, you need a good stable mount and a good seal around the panels and holes so you can mold from the door trim panels.
from the substrate (the board) you must not have any angles less than 90 degrees in the vertical plane.
 the injection molded process for the makers of the panels use shifting  molds that make the parts. (example-- if the sides are less than 90 degrees) the mold parts are removed from the part in the de molding process first from the center and then the outers slide inward .the tooling gelcoat is so stiff and if you make angles less than 90 degrees it will be unable to be removed safely.
oh ! fill in the edges to the yellow pads where they join the panels. also pay attention to the outer edge of yellow pad too, it appears that outer edge could be problematic for the 90 degree rule.  use filleting wax i think perfect case about the 90 degree rule.
and dont go easy on the mold release--follow the instructions, just be quadruple triple double sure you have it all coated well.

sorry if i stated any obvious things

keep the pics coming--

Thanxs a lot i done lots of molds and do fiberglass and carbon 5 years, only first time im thinking how to do for this flanges as i never done infusion

ye i try to update these panels i dont ant to destroy as they customers straight from Lamborghini

i try to update...

Hi Tom
I used hot glue as Matt demonstrated in his video. To be honest I had no faith what so ever that hot glue was going to stick to the corrigated plastic or the part when making the flanges. But I tried it and to my amazement it stuck and it stuck good!!
I think you probably have contaminates on your doors that are acting like a release agent to the hot glue.
I would suggest you degrease with lacquer or acetone. Even a fine scotch bright rub first wouldn't hurt.
Hope this helps.

Thanks a lot im going try my best as that mold is first so hard to add flanges..

i keep update if hot glue not hold good maybe i use pvc glue that a little melt both piece but hold like dead catch.
