Extrude beams from plastic waste #preciousplastic

Support us on Patreon:

In this video we are going to extrude beams from plastic waste using our extruder machine. They can be used to construct or build things.

For those who want to start a workspace yourself to make beams. 2 options:
We are happy either way. More plastic recycling! :)

A few suggestions as someone who has worked in injection molding and extrusion of plastic in my youth. Eye and face protection is greatly advised. I had foremen who got a face full of hot plastic working at the high pressure end, removing a plug, all from residual pressure. Insulating the heater barrel will reduce the energy costs, ours (back in the 1970's) had 3-6 inches of insulating material. You need a cover on the feed hopper for safety sake.

I had no idea this was possible outside of commercial recycling industry. That's awesome! I can think of a ton of uses and I love that you can recycle material you machine away with saws, routers, drills, etc. I would love to be able to do this but damn I've already got myself into a ton of other things LOL!

Really cool stuff man. I'm impressed.

[SeniorSoftwareVlogger]

Wow, I didn't think it would slide out so easy!

I used to work for a plastics company that did extrusion. You don't need all that bar! It's not that hard to make a die for a hollow tube too.
What you do need is a series of water cooled rollers that guide it out as it cools. By the end it's fully hardened.
The "die" is the really expensive part. Great idea with their system as is though. I would simply use a shorter tube. You can make the extrusions as long as you have enough plastic for.

Heat your molds before you cast, that how you get smooth shiny candles.

This machine would be great for making 'planks' for making self assembly sheds using the plastic poles to fix them to.

Yes, you can play with colors! The texture is great! Thanks ♻️🧱

Dear One Army, you could have better results if you let the oxigen flow away from the mold. Once it is completely full close the valve and let it cool. Greetings !! 🏆

Excellent job! Here in the states this technique would be so beneficial. Instead of using wood to build fence around our yards, use plastic colored like wood.

I used to work at a plastic extrusion plant. We made drainage tile, the large and small diameter pipe that is used in road and house construction. It went as large as 900mm down to 100mm pipe. We plastic welded bell caps (flange) on the pipe after it came out of the extruders. We also used big dies to form the pipe, plus pump water and air through plumbing pipes to get a correct wall thickness. We used poly pellets + we chopped up any waste with a reciprocating saw or band saw then it went down the shoot into the chipper. The waste would be pulverized and reused. Quite the process.

I'm very glad I found your channel, thanks for creating these videos!!

[SierraMatchett]

so glad that there’s actually videos about this, ive been thinking that it would be a really good idea to build structures out of recycled plastic. think of the amount that would finally be reused if we replaced wooden beams with plastic.

Dave .... Brilliant work ... just came across your project and viewed your website .. ...open source plans to download ... and so professional .. already I am figuring how to put a shredder and extruder into preparation .... this brings the process of recycling and re-purposing into a real world home process forget about the hand cutting of HDPE milk bottles and melting in the domestic oven ... I hope millions of viewers can recognise what you are achieving .... damn fine work. Oh and yeah the differing shrinkage rates will require a modified two part mould ... bolted together ... to release easily .... but that is what you are trying ... get others into the process of thinking how .... congrats Greg Brugman Bundaberg Australia

Dave deserves a medal or a knighthood for his work. I'd buy recycled plastic picket fencing and outdoor decking boards if someone was able to make them?

[robertoalvarez]

you give us your knowledge and teach us how to do all this great things, thank you so much and greetings from México !

YOU'RE AN
It's very disturbing how much plastic we put in our earth on a daily basis. This is something that truly bothers me!!!! It's nice to FINALLY know that other ppl think about it too. I was beginning to think that i was just way differently weird...lol
THANK YOU

the screw looks a lot like the kind that is used in clamps & vices. Perhaps they could work?

one of the most compelling things about extruded plastic parts is that they can be easily welded together with inexpensive, low energy and safe tools. (compared to metal welding).

this means you would never need any fixings & fasteners!

also if you didn't want to use heat (or solvent) welding for some reason, you can join parts using carpentry techniques like dowels, tenons, dovetails, scarf & lap joints etc..

I bought a guillotine paper cutter.
I tilted the cutter upright.
I stomped on plastic bottles, etc., with my feet.
I made a hopper to dump in plastic.
I placed a weight on top to push the plastic down.
I used my arms to chop up the plastic using the cutter.
I made a 2x4 mold out of wood.
I heated the plastic using a solar outdoor oven.
I poured the plastic into the mold.
I made 2x4 plastic beams.
I use the beams for shelving around my house.
