double wall refrigerator cell thermoforming

[polimi]

kind professionals,

I would like to ask you about the feasibility of the following project: a double wall sealed refrigerator cell

- is composed of two tanks welded along the flange, and welded also in correspondence of the two passing channels.
- plastic material
- technology used, possibly thermoforming and welding, but also other (rotational printing excluded)according to you can perform these weldings ensuring the stagnation?
Are there any other notices to ensure the seal?
Are there better production technologies for this application?

Thank you very much.

Hi.
there are glues and resins that are easy to find
that guarantee the bonding
do not absorb water do not create moulds resist to low temperatures crystallize after 10/15 minutes
and ready to use after 4/6 hours
you could get on the flanges to weld a male perimeter cord on one side and female on the other side
that are grafted between them also with 1/2 mm of lasco
in the quadre sunbeds in the possible attempt to create flanges for bonding
I hope you've been helped
Thank you very much

Gazie shiren,
As for the asola on the narrower face (the one facing up) of the first component, this is in the subsquadro, you can get it through thermoforming, or you have to use gluing?

Hello polimi
and feasible
the mold could also be sez in 4 parts plus the bottom with central mascho
two heads short side
two sides long
Sez. at the end of the rays
This way you have 4 parts that open
in case you should add a hole in that pocket

other hypotheses removable insert perhaps anchored with a swallow tail in the pocket area
The geometry you need to achieve is not very complex
Thank you very much

Last question... a little particular:

What measures should be taken if a filler or foam was injected inside the double wall, and then a large part of the air was evacuated creating a certain degree of vacuum?
is it possible for you to keep the void? Maybe welding all the channels?

Hi.
for foam perhaps you mean a liquid compound composed in equal parts equal to polyol and isocyanate
that when associated foam and expand
most likely you could create refills of the walls
Maybe we should create internal ribs to spray the walls
Some doubt comes
because controlling foam expansion seems complicated to me
why not think about fire-retardant setup carpets that are used in the movie industry
cut out and stick in the intercapidene before the paste
Thank you very much
