Title: Plastic welding
Post by: DY85262 on January 30, 2010, 10:42 AM

Ok over to you pros that work with plastic.
Is there anything I can do to weld my plastic number plate.
Well over the past 25 years it went kinda brittle and my plate keeper tried to bend the top straps around and they snapped.
Its like the Haro circuit board at the top.
Can it be plastic welded or a hot glue gun type thing used?

Sure it may go in another place but if I heat the plastic when bending it may help?

I guess I am thinking about the repairs done to car bumpers and motorcycle plastics.

Cheers

I doubt it. the force needed to bend that plastic will result in that seperating. Maybe a hot glue would do the trick. But again I am dubious. I have heard of welding and wondered if anyone had tried it out of teh BMX world we live in  :)
Good morning to Poole for me today. I do miss it being all the way up in Scotland  :)

Some welds go brittle depending on the type of plastic.
You might want to get some shavings off the item you want to weld and test it first :daumenhoch:

They use hot air guns to weld plastic ...  you could hire one from a tool hire shop, or if you know someone who does hard flooring, they use the same equipment .. i'd practise on something similiar first, they get very hot very quick ..

Some specialist motorcycle shops do plastic welding on fairings - As they're soo expensive to replace them
