Hot Staples For Repairing Broken Plastic.

If you have ever found it difficult if not impossible to weld cracks in plastic using glue this may be the ideal way to solve your problem. As someone who has done dozens of repairs on broken plastic devices I've come to the conclusion that some plastics can't be repaired by clue alone, so I'd often bend paper clips into various shapes and heat them up so they could be melted into the plastic for added support, but I recently discovered there was already a product on the market that used the same principle to mend plastic as I was using, except that it used a variable current source to heat the staples.
I use heated staples but on the inside of the piece to repair, to keep it neat. Sometimes I also use a product available here in Spain called Plastix-27. It's chemical soldering, and it's pretty awesome when you need to fill a gap. Look for a channel called KOVERBOND here on YT to get the idea about how it works.
I'm not affiliated btw, just a happy customer.
Thanks for the info. Project Farm is another good youtube channel which tests a few adhesives.
@@GrantsPassTVRepair Thank you for the recommendation, and for your channel
Protip: Twist a bit after pushing in. Increases strength a lot.
Surely you've heard of solvent welding. I'd be interested to see what sort of ultrasonic welding rig you'd come up with, might be up your alley anyway. Works on plastics and even some metals from what i've read
Hi Grant: I use hot staples too, although in some cases I use a hot knife and the idea is to burn diagonal or cross ditches, then scoop some molten plastic back in to the grooves. It works well usually, I do it with a low temp soldering iron and flat tip. As far as glue, the best glues strength and durability wise are usually epoxies however any Methyl Acrylate based glue is usually perfect for plastic, as in hobby glue etc
To repair the body panels on old motor scooters use a piece of the busted panel and melt it into glue using a small amount of acetone. You can also bury staples using acetone by softening the plastic with it and pressing the staples in. (Remember when you was a kid and put too much airplane glue on your model kits and the parts would go soggy. Same concept.)
Interesting idea on the acetone.
What a neat and useful device.
Very, very useful informations!
i think they used something like this on the old school bus seats. those weird looking stitches.
It really helps, thanks sir!
Thank you for the upload :)
Hmm....not bad, I would heat up wire with the soldering iron and use that to hold plastic together....I never knew about the staple strip heater.
Hi Frank. I wish I had known about these years ago, but better late than never.
Interesting idea to use a soldering iron. How about a soldering gun?
@@waltschannel7465 If you could figure out how to attach the staples to the soldering gun it would probably work, but is it worth the trouble when you can buy these devices new for so little?
Very I threshing idea. I used a hot hobby knife to heat up finishing nails and tried to use that to fix a handle on a cheap wire brush (the kind that HFT used to sell 3 for a buck). I tried melting the plastic at the broken joint and mixing it to affect a repair, but the plastic would become brittle. Reinforcing it by sinking metal into it did not help. Interesting idea to use glue or acetone. Does the composition of the plastic matter? Polypropylene vs. PETE vs. ABS, etc.? I'm guessing the yellow blower is probably polycarbonate or ABS. Is it possible I applied too much heat, or too little?
I'm not sure what kind of plastic the blower is made of, but it sure made a strong repair.
@@GrantsPassTVRepair OK, thanks
I’ve always used a plastic welder with filler rod.
Plastic welders if not used properly sometimes welds only near the surface providing a temporary repair at best, particularly when repaired part may be subject to vibrations. Many are getting excellent result using a hot stapler the bond deeply and then the plastic welder for added strength.
@@williamnewsome5169 “If not used properly”, “sometimes” doesn’t this apply to any process you you choose including hot staples? 🤷🏻♂️🤣
I wish you could replicate don smith resonant transformers since you have long exprerience with antenna tuning
Try Panel Bond adhesive, it's used in autobody work as well and it's really strong! I have one of those guns for fixing plastic on motorcycles & quads.
Panel bond? Is that the name of the actual glue? Does it have a parent brand name?
I've used panel bond adhesive and found it became brittle over time, but perhaps it might work in combination with hot staples.
@@jjhack3r It's a name & description of what it does.
@@GrantsPassTVRepair If it's exposed to UV light it could become brittle. Usually it's used to glue body panels on vehicles so it's probably not designed to be exposed to direct UV.
4 lithium ion 18650 cells in parallel might be more practical. It would be more controllable at 4 volts rather than 12v. I would use the high amp cells from a drill battery but don’t use them as an 18 volt pack haha. You might want to look into ultrasonic welding. Specially ultrasonic plastic welding. You might be able to make something from an ultrasonic mist maker or ultrasonic cleaner.
Thanks for the tip on the lithium Ion battery idea.
Do you accept mail-in repairs? I have a SONY CV-2600 in very good condition but non-working, comes with a service manual.
My apologies but that's not something I work on.
