Laptop case repair?

Question

Do it yourself

Guys help me out, the laptop cracked in two places.
1) The plastic radiator grille on the laptop case cracked in 4 places and 1 plastic plate came off, 7mm in size.
2) There is a crack along the bottom of the laptop centimeter 4.
How would you advise to glue it?
Now I'm considering 2 options:
1) POXIPOL
2) Metal Bond
On the bottom of the case from the inside, under the glue, I think to place a bandage for a better effect, so that the glue soaks and fixes it better.

Answer 1

Nothing good will come of it - neither one nor the other will have sufficient adhesion to the plastic, on their own, and will simply peel off.
You need to find a marking of what plastic the part is made of, treatment with some 3M Polyolefin Adhesion Promoter or something similar can help.
Well, not a useless bandage, then, which, in terms of tearing, will not be much better than the resin itself, but some thin fiberglass ...
And not poxypol, but epoxy / polyester, more liquid and without filler, since something will happen soak...

Answer 2

There are many thermoplastic substances to which almost no glue adheres, even the notorious "second" cyanoacrylic (for example, it is polyethylene). So my recommendation is welding . And not just heating and fusion, but with reinforcement of the seam with a fine brass mesh. We take a soldering iron and press a strip of mesh into the plastic on the back of the panel with a margin of 5 ... 10 mm from all sides. It is difficult to repair the radiator grille with a mesh - there a 0.5 mm copper wire will come off as a welded reinforcement.
You can get such a mesh by dismantling the old used oil filters from auto and aircraft equipment.

Answer 3

Superglue and fabric. I did this to a friend on a netbook, while there were cracks on the laptop lid near the hinges (the force when closing and opening is quite strong). It's been working great for six months now. It’s only good to impregnate the fabric, but I don’t know what to do with the radiator grill, since the contact area is too small.

Answer 4

With uperglue + soda . Reinforcement with a bandage will also help.

Answer 5

used superglue and fiberglass mesh to repair laptop case

Answer 6

At one time, Superglue + soda helped me, with this I "built up" plastic (Cyanacrylate). For gluing, you can use any mesh (be it a bandage, or as advised above - fiberglass). Strength depends on the quality of the adhesive. If the load is not large, you can use the "Epoxylin Moment", this is a two-component similarity of plasticine, it freezes when mixed, sooooo long, but very durable. Then you can grind off with a needle file, give shape.
