  • Kubota8540

    Good afternoon all,

    I'm pleased to become a participant (and newest member) in this forum. I'm not an expert welder but am gaining experience and really enjoy the time I spend working on projects. I have two MIG welders, one "stick" welder, an oxy/acetylene welder and a "plastic welder.

    I've retired from the phone company after more than 30 years. I have a degree in Civil Engineering and do all my own work on our vehicles, house, tractors, fences and what'all.

    I look forward to reading, learning and maybe even one day, helping someone in return for all I hope to be gaining from this group.

    Regards,
    Kubota8540

      Plastic Welder

      dHi Signwave,

      The Plastic Welder is called a "ThermoPlastic Welder" and is made by Pamran Elec. Co in New Jersey. It welds ABS,PVC, PE,PP and TPUP. The inital cost for the starter kit is around $180.00.
      I'ts essentially a heat gun with a smaller nozzle, filler feeder and whatever other accessories you desire. I installed a PVC fence around our pasture for the horses and used it to weld the joints on the gates I made. So far they've held up well.
      After you "weld", you have to let it sit for 24 hours before putting maximum stress on the joint. If I use the word "vulcanizing" as it refers to rubber, this is doing the same thing only to the plastic.
      Here is their website if you're interested: www.pamran.com/

      Regards,
      Kubota8540

          That plastic welding does look interesting. The only trouble I see is keeping the base plastic and the rod at the right temperatures so you get an even melting process for a smooth finish. I imagine its a lot harder than they say on the web site, at least until you catch onto it.

          Would be a good side to get into though, not many plastic welders around. Like I read in another post, we are getting into a throw away world and buying new. Right now the economy is slow, money is tight, repair the product at half the cost of a new one.

            Ken,
            You're correct, it's not as easy as one might think. The base material has to actually draw the fill material into it. Keeping the base at the correct temperature without "puddling" is a challenge.
            The "High Speed Tip" is a must if you do extensive joints as I did on the gates. It's also expensive for the little thing you get. I also noticed that the welder has increased 33% since I bought mine.
            The only other thing to be careful of is to match the filler with the base. There are 5 types of filler rods to match the material being repaired.

              Hmmm sounds a bit like working aluminum.

              There is a distributor in vancouver called GE polymer shapes. Or ther used to be. I think they just sold out to some other comapny, but anyway, these guys carry all kinds of plastic shapes and sizes. lots of different grades and types of plastic too.

                      there are many differences.
                      some that i know off hand are:
                      polycarbonate= (lexan)pop bottles, peanut butter containers. usually a clear plastic with high tenslie strength. will "shatter" if hit hard enough.
                      polyethelyne= milk jugs plastic usually feel "slippery" to the touch may be any color chosen. it is wudely used in many applications from buckets and pails to ivory soap dishsoap containers... etc.. very flexible, resilient but will shatter (split and crack) if hit hard enough due to shock.
                      ABS= black plastic plumbing pipe, computer cases, motorcycle fairings, most toys and a number of other objcts. it is fairly ridgid and somewhat flexible. IOIt will deform on impact or deformation. Cannot be fitted back together without some reshaping.. (the plastic from h e l l ) very good candidate for welding.
                      nylon= the "super plastic" flexible, durable, strong, it can be used as bearing material on some applications. it is used for insultion on wire, it is used in parts for R/C models. repairable and can be pricy for raw product.

                      there are a ton of ohters. each has its use and properties.

                      Check out the dupont web site for more info or simply search out plastic on the www.
                      hope this helps you a little.

                        HMV,
                        Yes, by shaving a small piece of the material to be "welded", lighting it with a match, the color, aroma of the smoke tell you which type of plastic you're working with.
