I would think you need some hole to release trapped air or it will be forced into the molten plastic and make voids in it.

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.

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..

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.

[@jamescarlin569]

I've been researching this because wood prices are getting out of control

[@RobMacKendrick]

Plus plastic lumber is just better than wood for some applications. I make a lot of stuff that has to hold up in a hostile marine environment, and plastic beats everything but stainless steel for many of those applications. Problem is, finding the actual plastic stock and fittings you need. Enter the Precious Plastic plan!

A wood 2x4x8' is only $4 a home depot. You can't make any material of the same dimension and volume for that price assuming you calculate your time into the cost.

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).

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.

I guess that's just a little bit out of the league of casual KZbin production. What could be possible is blow-moulding plastic foil. Plastic sheets like those for windows, etc. are often produced on wide extruders like here (kzbin.info/www/bejne/h2eWeahjbcyJa80). Maybe we'll see a small plastic sheet, maybe a few centimeters wide, that would already be pretty cool (not even speaking of clear sheets)

buenas,donde se puede conseguir esa máquina,y cuanto,cuesta?

[@user-tr2dh4xx6u]

@@dominikschaefer7626 nah you could extrude it through a thick rectangular heated pipe, then send it through some rollers. Probably watercool the rollers to help stiffen the plastic as it rolls out. The hardest part is timing the rollers to match the extrusion speed, set it too slowly and you may get a buildup of plastic around the roller. Too technical to explain in a comment. It is possible though and can be done simply. If you started doing extrusions in the first place, this wouldnt be much harder

[@user-tr2dh4xx6u]

@@dominikschaefer7626 infact if you made the plastic exit the rollers vertically into a cold waterbath you could instantly harden it and create a uniform sheet. If too much plastic is extruded then it will simply make a wider sheet of the same thickness which could be trimmed

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.

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.

Eric Cha I was thinking the exact same thing

Right. Go to Lowes and look at how much they charge for the Trex board. You could make a fortune.

Yes and no. This plastic is not UV stabilized. It would bleach out and begin degrading in very short order. Some plastics end up brittle and will go to powder in just a year or two in direct sunlight. It would require additional additives to stabilize and make it useful for that.

I don’t think the raw plastic Will hold up well under UV exposure

[@dreggory82]

I wonder what those additives are, and if it can be DIY on the cheap.
