Weld plastic parts together

by Johannplasto


If you want to join several plastic parts together, you can join them together at the joint surfaces with a simple soldering iron.
It's quick and you don't need any additional material. —

    Step 1 - Choose your soldering tip

    A very stable connection is created when the connection surfaces are first welded deeper and then at the edge.
    For the deeper welding, a thin soldering tip is suitable and for the edge seam a larger one.




    Step 2 - Choose the welding temperature

    Do some temperature tests.
    I use around 250 ° C for HDPE and 270 ° C for PP.
    Please use a gas mask for this work!

    Step 3 - Weld it

    Position the parts and fix / clamp them.
    Weld the parts first with the thin soldering tip and then with the thick soldering tip. Not too fast!
    Check the connection and change the parameters: temperature, welding depth and speed if necessary.
    Happy melting!




    Step 4 - How to make the lamps

    The recycling guy in this video shows how he combines 12 plates to one hanging lamp ;)
    In addition to HDPE, you can also use this welding technique with PP. LDPE or PS.
    After welding, you can also improve the edges. I rub with additional hard plastic over the edges, but you can also polish.
