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.

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 !! 🏆

[@dfpguitar]

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 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.

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.

[@leofortey7561]

Main issue with replacing wood with plastic is load capacity at a given length. There are many other wonderful uses for this type of recycling. Plastic shingles or furniture. There is a reason wood is the 'standard' in building material. Ease of availability and high functionality. imgur.com/a/nvb0J3H There are materials you can blend with the plastic in order to increase any characteristic you want. Carbon fibre is one. Here is a study worth reading: qurl.org/jnV One common use is wood-blended plastic deck boards.

[@harleyb.birdwhisperer]

Lots of wooden fence posts would stand up longer if they were plastic, perhaps with an embedded tube of chicken wire.

[@poisonduckee]

If you coated the inside of the tubes with 100% petroleum, slightly heat the tube, and put more pressure on the material flowing into the tube with a piece of steel instead of wood, you could get a much better finish on the product.

[@PocketBrain]

@anarchore I think he means "petrolatum" also known as "petroleum jelly." I think the key here would be to get it to coat evenly (via the heating).

[@cndbrn7975]

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.

The problem with most of the machines depicted on this channel is they require welding. For those of us who can not weld, either due to lack of skill or lack of equipment, these machines are pretty much impossible to make. I wish Dave would design some versions of his machines that do not require welding, either replacing metal parts with wooden ones, or using bolts and screws. Being able to use less expensive materials that are easier to obtain would be handy as well. The only store here in town that sold stock metal recently closed, making building most of Dave's plans unbuildable. Having all these wonderful plans is great, but if I can't build any of the machines they are useless to me.

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 poured the plastic into the mold. I made 2x4 plastic beams. I use the beams for shelving around my house.

Because it's too difficult to do. You have to have enough raw material, and it has to be clean enough. You need people to do it, and those people need to be paid.

They may want to sue the municipality. The only sensible solution is to have a more centralized facility rather than one in every municipality, but then the final question is what does one of these beams cost compared to other materials of equal performance?

I need your help, I work in surfing and diving club. And every year we throw hundreds of wetsuits into the trash. I always stand and look at the pile of bags full of wet suits, thinking about taking home and recycle alone. but I fear that I will be stuck with many suits and unable to return them to their original raw material. Is it possible to recycle Niaofriim? And I do not really want to make hundreds of cases for laptops like KZbin suggests

[@baladar1353]

If you work in a surfing & diving club, then you should know how to spell neoprene correctly. You could try tho heat the suits gently, then force the material into a form, or into a pellet-maker, then you can sell it.

key is for them to be made in a way for the materials to be reclaimed non toxically ... start them doing that and many more things would be possible

[@sugars205]

A small company near me does this and makes ever-lasting decking boards. They use the waste product from a local bagging company. Unfortunately though, it's not cost effective as the effort to make these board is far more expensive than timber boards.

You may add a construction steel bar to the inside of your polymer Beams for more stability.

I WAS THINKING THE SAME THING ..AS AN ENGINEER (RETIRED) THIS PLASTIC RECYCLING FASCINATES ME

[@jdamianc7]

May I ask you how do you know when the mold is already full?

[@mevofr]

I asked myself the same question.

[@DrewJackson94]

The other end of the tube is open, so you can see when it is full.

[@Joshua79C]

From my experience working for a recycled plastic company we used open end molds and though our method was different, we cooled the molds in a tank of water below the injection machine and one way was to watch the water evaporate or dry out on the metal but best was to use "touch as the end or start would be warm enough you can touch to see where it is for length. I worked on the extrusion as well as shredding processors and drove the company truck to make local deliveries as needed for the owner.

[@JeffMTX]

the motor will load up and moan ;) you could also watch an ammeter to see when the current jumps up

[@mikem6549]

Would be interesting to see what happens with a shorter open ended tube so that you would end up with continuous unlimited length beams. Perhaps I section for more rigid light weight components.

[@seanrodden6151]

Mike M The most likely consequence would be bending and twisting. You'd need a fancy system that cools the plastic before it's free to wander.

How to make a 2.4x1.2m (4x8') sheet ☺️

[@pongthonlianghirungul1516]

i want to know too

[@neiallswheel]

I guess you'd need a hot mold, I know that when they pour UPVC mouldings ( window frames etc..) The mold is pressurised . this could be achieved with weight but the mold would need to have some weight.

[@drackar]

First, figure out shrink, then build the appropriately sized frame (2.45x1.25m, or something similar as a top of the head guess) which is warmed, flow plastic into it, and then put in a top plate and compress.

[@riippumatonlinja]

@@drackar Yep, only problem with that is, that sheet machine with heated bed like that costs thousands. Enought strong metal bed not to warp and heating elements(if you dont want to get fumehood or other safety issues) are alone allready pretty hi cost.

[@Pennyadodumuss]

Piers and docks made of plastic would be excellent.

[@adamwarren4512]

How do you get the machine?

[@joeblack4436]

I would experiment with including various metal rods to make a composite material. That should lead to something with significant strength while saving metal.

[@nelsondisalvatore9812]

Can you make flat pannels or maybe shingles with i??

[@arbonac]

Good idea!

[@Indy509]

I would check out the type of plastic first. As plastic doesn't bio degrade, it photo degrades in sunlight, roofing shingles may not be a good idea. Depends on the type of plastic though

[@nelsondisalvatore9812]

Indy509 you can easy paint the things, thats my guess or perhaps add some uv aditive in the melting process to make it resistant to the uv light.

[@matthewstanton9633]

Nelson Di Salvatore. Not a good idea for roofing massive fire risk just one wayward spark from a bonfire or a fire work and goodbye house

"Recycling plastics is too expensive." Then there is this guy.

[@Salazarsbizzar]

you should build children's play forts with it. I built a modest one from green treated wood 15 years ago and it set me back $5000. and it still had several problems. obviously your plastic beams are far cheaper and better for the environment, don't rot,no spinters,no paint. seriously you could make a lot of money with those

[@pierrec1590]

If your mold was hot enough, the surface would be much smoother.
