What to fill in the breakout (hole) in the housing?

    It sometimes happens that a piece of the casing (on the corner, on the side, etc.) breaks under undefined circumstances and then the wind rushes around the casing. Recently I was wondering what could be filled in such a hole? Initially, I was thinking about some Poxipol, which then could be nicely sanded and possibly painted. However, its original purpose was hardly ever the filler.
    So, has anyone already tested some means that could be used to fill a broken plastic housing and then (though not necessarily) grind it nicely?

    Hello, recently I was repairing a hole in the plastic casing (hole about 3 cm) by filling the cavities with "EPOXY" putty - epoxy metal repair compound. After hardening, it is perfect for further processing, it is very hard. After sanding, I got a perfectly smooth and hard surface. Regards Janek.

    I recently used poxilina (I combined plastic with metal and filled metal losses), but it needs to be modeled quickly because after 5 minutes it becomes hard and cannot be moved.

    I used to use two-component adhesives - poxipol and similar.

    Someone will write with plaster in a moment. How much does EPOXY cost?

    I complement it with plastic, similar to the one from the given housing. I stick to what the plastic holds. Then processing with a file, 300, 1000, 2000 paper wet, polishing. Effect - it's actually hard to notice anything. I have repaired, for example, rear lamps for a car or defects in a mobile phone - when I was selling it later in a purchase facility, they did not notice it, even though they carefully looked at it.

    if the housing is made of ABS (and this is most often the case in PCs), then just cut a piece from another housing or the plugs and melt in with a soldering iron. The corner of the housing can be bent in advance by heating with a heat gun or over a gas

    ABS is the same as car bumpers

    Recently, I used PermaPoxy plastic glue for small holes and cracks. Two-component fact stinks mercilessly. But after binding
    behaves almost like the original material. Easy to process with a file or sandpaper. I recommend. Only this stench .......

    I also use a two-component epoxy glue, but it did not cost me more than PLN 6 and it works just as well - it is quite thin at the beginning and it dries two days, but after drying it is hard and flexible at the same time, besides, it is easy to sand down. So that nothing is visible from the top, I first glue the bottom with a piece of plastic, because the glue is quite thin and otherwise it would be difficult to fill the hole with it, the hole in the housing so that the piece of plastic on the bottom is larger than the defect, then I pour the epoxy mixture on top and leave it until solidified. I sand the excess with sandpaper to level the surface. Then I paint the whole thing with "deodorant" and it's also hard to notice anything.

    You can also trace a hole on the paper, cut it and stick it on the treated piece of plastic with which you intend to fill the defect in the housing - there is more work and the effect is the same, but less glue comes off :)

    As for the wind in the housing, I think it is appropriate, but it was probably just a metaphor.

    I paid PLN 14 for Epoxy. Regards Janek.

    When I changed the look of my casing, I glued it with poxipol and the rest I did with a universal, finishing putty (the one without additives). Easy to process, cheap and looks very good.

    In my opinion, it is best to fuse the plastic pieces with the soldering iron in the cavities. I 'glued' many cases in this way, especially for Toshib with broken corners and the effect is amazing. In fact, after painting by a friend of the painter, they look better like new.
    The glue is fine in places where the housing does not bend. In the case where the hole is in the place where the housing bends slightly, the glue will go sooner or later.

    You can buy a skin for a laptop.
    Then it will look very nice.

    Hmm, has anyone tried fiberglass? Later treatment with putty for cars.

    Car putty, maybe hot glue?

    It is best to fill the defect with the same type of plastic and weld a plastic welder / hot water machine and then treat it with paper, including water. Putty and epoxy do not work the same thermally or mechanically as plastic, so they quickly separate from plastic, unless it is a solid and non-working material.

    You can hot air, but you can also make a lot of trouble this way. The casing likes to shrink at the point of the crack and additional larger holes are created. I used to stick old, tired plastic like that and it behaved very unpredictably.

    vogelek23 in my opinion it is just a waste of time, you should buy the entire laptop, not just the case :) who would waste time on such stupidities as replacing the housing :D

    A colleague of vogelek is somewhat right. It all depends on the finances in this matter. Either we like the casing and I glue it, which usually takes a few days and also costs, or we buy a new one, which does not cost a lot.
    Personally, I glued a few flaps, but only because the new flap cost 1/4 the value of the laptop. Usually, however, it is a maximum of 1/10, so I replace it with a new one.
    The whole procedure consists in fusing pieces of plastic with a soldering iron in the missing places, then grinding and painting with the cheapest primer and car spray. The can costs 5 PLN here. The hatch looks like new.

    You put a piece of plastic in this place and stick it, then putty it in place, after the putty dries, you sand it with sandpaper.

    I also used two-component adhesives that are the best

    For larger losses and the possibility of grinding, I use a polyester car putty with glass fiber. It hardens for half an hour. For small ones - rather epoxies. Pasting with a soldering iron only occasionally - often increases the area of damage. I happened to reinforce a cracked laptop cover with a bent piece of aluminum stuck to epoxy. If the fracture site transmits high forces, then filling the cavity alone may not be enough.
