Best Glue For The Job?
I've never had good luck with glue on plastic. The motherboard on our dishwasher was loose so I took it apart to have a look. There are 4 protruding plastic parts that screws screw into in order to hold the motherboard secure. There's going to be a bit of force on the glued portion of the plastic parts from putting the screws in and from opening the dishwasher door. Is there a glue on the market that would work for something like this? Maybe one that actually melts the plastic together. I also want to put glue along the edge of the motherboard where it is against the stainless steel of the door.
The motherboard costs too much so I have to find a way to repair it. https://i.imgur.com/gjJBeVQ.jpg |
Isn't this the new one you just installed?
Go with Gorilla Glue. I use it all the time, I even seated a knife blank into an deer antler handle during Christmas with it, It is never coming out. Lots on the shelf at Home Hardware here in town. Hurry they close in an hour!!!!! |
No glue is going to "melt" it together. Pick-up a 2 part epoxy for plastic.

Those two piece are weak and will break if you just glue the broken joints , Hold it in place with a little super glue( dollar store) ...then on the outside use gorilla glue, it expands and like a little foam will form around the bottom and top piece wrapping it like a cast so secure it in place .

Get a 3/8" length of screw or ready rod, screw it half way in to one piece, add glue and screw on the other piece. Grind a bit off the screw that has to normally screw in there if you have to. There is nothing that will glue that to be as strong as it was before but adding a little piece of screw or ready rod will make it nearly as strong as before it was broken.

Plastic cement - modeling glue. Works wonders.

Bondic, I'll never use glue again and it's great for fixing old lures and the like, and perfect for what you're trying to do;

Kidding. Is it still semi soft or pliable when cured or hard? I may retract my previous suggestion Colin |
That looks like it might be an ABS plastic, how about simply using ABS pipe glue? I have on occasion used it for things other than just plumbing and built up multiple layers of it when necessary. If it is ABS you could also make little reinforcing splines out of a piece of pipe cut into straight slivers.

Good luck.
Trash man is my best friend for plastic. Goobegone is my second best friend for exploaded expanded blownapart 4x8s of woodchip glued together plywood. To the dumpster they go. :-) I wont put that crap in a burn pile, but other people love that stuff, can't get enough because it's cheap like oh hell ya. |
Loctite 404 General purpose glue works well on plastics,
Like a crazy glue product. |
Sorry about the rant but I'm about tired out from trashing out other
peoples mistakes or short falls. Rebuilding and fixing other peoples "stuff" over all these years has gotten old. Can't say how many times I had to trash out something that was done on the cheep instead of being done right over the years. But it's been a lot. It get's old after a while. Funny thing is younger people have no interest. As I see it. Don't matter, no big deal. So.. an old fart sets it gas away on a wing-ed wind. Will someone listen ? That is the question. )-: |
Yes, there is plastic-specific 2-tube epoxy glue on the market which works really well on plastic. Canadian Tire should have it.
Nice thing about it is, if you are really careful and have room, you can build up a fat cone of epoxy around a snapped mounting point for screws or tabs etc. which is much stronger than the original thin factory casting. I would not mix different kinds of glues in this case, just set the broken part with the epoxy, and then work up a rough cylinder around the broken area. Of course, it has to be set perfectly straight with all the broken edges perfectly keyed together before building anything up. I'd do it in two stages, and set up a good vice or clamp for it so nothing moves. |

If I was a bald man, I'd be about pullin' my scalp off by now.

Thank God theres crazy glue and PVC Cement so I can put it all back
together come spring. :sHa_shakeshout: LOL thanks I needed a good laugh, it has been a long cold winter. |

it's still plyable but with a bit of practice you can fix most things pretty good, for dave I was thinking just fill the hole (it stays liquid till UV light hits it, so a little, hit with light for 4 seconds, little more>UV it, then attack broken off bit by filling screw hole bit by bit, then drill a smaller pilot hole through, and put the screws back in). Not sure if screw hole is allowed on AO, but there it is. To Bonescreek; we are proud as screw hole frugal Albertans, it's our way, we do not waste anything. Caber owns a ball off elastic and twine that could wrap the planet thrice, and it has been heard across a prairie lawn a faint tap tap tapping of a member straightening bent nails to be used on his dream home made of old skids and runaway round bales. |

There is much more to life than hair.
:) With or without, color or not. Life is what people chose to do with it. And in the end, what is left behind is what matters most. A foot print of your life. :sHa_shakeshout: To last forevermore. |
Didn't mean to bring yall down,
Just got side swayed from the winter coming down. Springs coming on, the wind keeps blowing, Warm Summer sun keeps on creeping on And it wont be long. :) |
2 part epoxy. Rough up the outside where they join with sandpaper then glue it together and generously apply epoxy around the outside to provide the primary strength(just trying to glue the mating surfaces together likely won't hold up over time).

You want to build up an epoxy collar around that whole deal which will grip to much more of the main shell. Of course, your reinforcing shank and a built up collar together would be still better. |

you could encase the two parts in *west system*

I just had a thought. What if I could level the surface where the plastic piece broke off and I glued a nut to it? I would think that it might be stronger than gluing that plastic piece back on. Is there a glue that would hold the nut tight and would this idea be feasible?
Maybe better yet, if I forgot about gluing the plastic piece on and applied an epoxy in layers to build it up, would I be able to drill a pilot hole into it that I could screw into? |
What about PL400?
Yes I know it is in a huge tube. This is what I know; when I used PL400 on the bottom of a 2 x 4 on concrete and had to remove the 2 x 4, it pull the concrete from the pad....That to me is tight. Now for other smaller items I never tried it. |
