As an ameteur its actually quite easy to weld HDPE togethr, On ebay you can buy hot air welders from around thirty pounds, and you can buy HDPE welding rod from ebay cheaply too. Then all you have to do is tack the plates together from the rear, and seam weld them, so the front face stays nice to look at.

Thanks for letting us know it's hard to seam weld HDPE as that was my plan (to make squares and seam weld to make boxes). But would like to know what you tried and what happened, with the seam welding. I've seen a video on seam welding corrugated sewage tubes and it didn't look too hard, with the correct tool. What did you try? Thanks.
@AtomicShrimp
5 жыл бұрын
For seam welding, I first tried adding material and heating with a hot air gun with a narrow nozzle - it didn't heat enough area at any given time, so the weld was patchy/ Next, I tried sprinkling ground HDPE into the gap and heating the whole area with a clothes iron (with a nonstick separator sheet) - this heated too large an area and caused some of the existing pressed sheets to buckle. I then tried heating just the area of the seam by pressing with a heated metal bar, but this didn't have enough thermal mass to deliver heat consistently to the seam - so it created a weak join. I think the way they get this right industrially is all about consistency of heat and material application - hard to do on a small hobby scale

Good effort but, you DON'T need to grind the HTPE if you're melting it in a sandwich maker. I just cut milk bottles in half lengthwise and melt them half at a time, adding halves as you go until you have the required amount. I just press down hard on it initially, and the container will collapse quickly and start melting. If you are preparing for an extruder/injector, then you will need to grind it.

The problem with steam welding is probably the steam. The parts should be hot to begin with and the edges to be joined may be heated with a heating element held near the work pieces. There are two reasons for the preheat: It takes less effort to get the edges to fusing temperature AND... Plastic expands a great deal when heated; if the pieces are not close to the same temperature all over, when they cool, the edges joined will shrink too much and be in great tension. They will be likely to break. Too, overlap joints are better than edge-to-edge joints. Use pressure to thin the joints while they're hot. Don't use material that is thicker than you need. Remember that plastic is a lousy conductor of heat and take time to heat all the way through. Look up information on "plastic welding." It absolutely works.

I have an insane idea. Get a drill press. High amp and with a three pulley system. You can get those for 100 dollars used. Those small bench top models probably won't work. They have only 2 amps and only two pulleys. Here's the insane idea. Lay the thing sideways on the workbench. And then you can directly hook it up to the meat grinder. Naturally, you're going to set the pulleys on the lowest speed. You're probably going to have to go to town with a bunch of two by fours to block the drill press in and support it so it's not wandering and vibrating all over the place.
