Precious Plastic – Build the extrusion

Precious Plastic – Build the extrusion

welcome to a new precious plastic instruction video so today we’re going to build the plastic extrusion machine basically this machine poops line of plastic it’s a little bit like this old toys we had to run a kit when you had some clay and you could squeeze it into little shapes and forms only this time we’re going to do it with plastic you can use this technique to make raw material like 3d printer filament or granulate or you can find another creative way to use it in this video we will guide you step-by-step how to make the machine you can download all the technical information and the blueprints and if you have any questions or something is unclear feel free to post the topic in our forums let’s get started alright so this is the machine we’re going to build it consists out of six different components we have two hopper the barrel the nozzle the barrel holder the framework and the electronics I’m going to start off making the hopper this is where the shredded plastic goes into the machine let’s build a hoofer you we finished up the hopper and now we’re going to make the barrel this is a crucial part of the machine this is where the plastic gets heated and compressed the measurements of this barrel are based upon the universal plumbing system so they should make it easy to find a tool set like this to tap the wire here we have the barrel and inside this barrel there will be an extrusion screw but before we gotta edit a brief lesson on extrusion screws so here we have an industrial extrusion screw it’s a big one and it’s expensive what these things do is that they transfer plastic from this side to here however this one is conical which means the gaps here are bigger than here so while it’s being transported it’s also being compressed so you can build a pressure but like I said these things are expensive we find a more affordable way to do this which still works properly by using a good drill and this goes inside the barrel make sure the pipe you use for the barrel is completely smooth from the inside so this crew fits in perfectly and as you can see when we turn the screw it will transport material forward a quick tip when connecting the hopper holders already attached them to the hopper and then you can put this one on so when well that you sure you have the right angle the barrel finished and the hopper fits perfectly we finish the hopper and the barrel and now we’re going to make the nozzle this is what we can control the output of the plastic so we finished up the nozzle and looks pretty badass and now we’re going to connect it to the barrel you can just screw it on here and make sure it’s really tight and this crew is used to adjust the flow of plastic that comes out and this one right here the term is the shape of the plastic so for instance for this one we made a small little round hole but you can also make a cross or a flat one a lot of holes and we like to use this nozzle because well we can adjust the flow of plastic that comes out however since it’s built upon the universal plumbing system you can easily change this nozzle for another one and we recommend to play around with these things because there are many options possible pick it something that fits your needs we finish the hopper the barrel and the nozzle and now we’re going to build the barrel holder pretty simple but it’s needed to hold the barrel together on the framework this thing is pretty straightforward just some metal tubes and angles so we’re going to weld this all together and then it should be ready ready for the next step alright so we finished the hopper barrel nozzle and the barrel holder and now we’re going to build the framework it looks like a lot of work but it’s quite easy hey mr. an overhaul havoc the framework is finished we painted everything and connect it together make sure everything works and then the last step is to connect this one to the frame and we like to put it with and also slightly out but you can put it here or here doesn’t really matter that much so we’re going to connect it and now we’re going to wire up all the electronics almost done we finished a hopper barrel nozzle barrel holder and the framework now the last step is to electronics we’re going to make this metal box and wire up the temperature controllers and the motor and then it’s all ready okay so first thing we need is a temperature controller and they come in different shapes and sizes with big one and all to one a crappy one a small one we like to use this one we will attach this cable which measures the temperature which he will understand they will connect a solid-state ruler to this with this heating element so temperatures measured controlled and then sourced to this little vent heater we’re also going to connect a switch and a little light now we’re going to wire it up with some cable connect everything and attached to the machine this might look super complex but it’s quite doable if you follow the schematics this looks super complex it’s quite doable if you follow the schematics Oh for your ghost these are the heating elements for the extrusion machine and these three are connected to this controller and this one to the top one that’s because the nozzle wants to be slightly higher temperature and this is the thing that measures the temperature so we just going to connect this in the heater alright so after we finished up the heating elements we’re going to look for the motor this should do it we found a slow powerful engine on the scrapyard if you need to know the specifications it’s in the blueprints right now we’re going to connect it extrusion machine is ready we did a few tests everything works but before we’re going to show you how it works we would like to add a small suggestion so currently the nozzle decides the amount of plastic that comes out however a better way to do this is by having a controllable engine now there are different ways how to control the speed of an engine by different controllers or regulators and these things tend to get complex and expensive but if you have fun lying around or you understand how it works we highly recommend it if not just use motor with a fixed speed with this nozzle you’re good to go so here we have our extrusion machine and before we got to extrude some plastic we first need to heat it up and we’re just going to turn it on and we’re going to set the temperature the temperature depends on the types of plastic you’re going to use so make sure to set it properly and then we wait about 10 minutes and we will extrude some plastic the machine is heated up and as you can see the nozzle is slightly higher temperature than the barrel that’s because this makes it easier for the plastic to flow out and now we’re going to turn on the engine and put some plastic in that’s a smooth line of plastic so it always takes a while before you have the right extrusion settings but once it’s going you get this nice line of fluid plastic to create new things even it might take you well before you find the right settings between your temperature your nozzle and your speed and also depends a little what you want to make for instance this lampshade required a higher temperature than this 3d printer filament to make but to help you get started we added some reference material in the blueprints so you should download that and tweaked a little bit yourself and you should be good to go thank you for watching the video I hope everything was clear if it wasn’t feel free to post topic in our forums and one thing to note is that the machines are built in a modular way which means you can always upgrade or repair them but also customize them to your needs so if you happen to made a hack or customization we would absolutely love to see it because in this way we can all work together to create better machines in the next video we’re going to make molds and show you how to create things with these machines and for now thanks for watching good luck with building and hope to see you in the next precious plastic video you

  1. Hello I am very interested in your project I would like to be able to obtain the plans to be able to do them in a Mechanical Engineering Innovation…
    The project to be made of the race is about the renewal of plastics in the manufacture of reels for 3D printing…
    Porfa requested your help Help me with the Blueprints if you can do so I leave my mail.. [email protected] …Please help me with the list of materials to be used for construction

  2. hola soy Alexis es genial sus ideas para maquinas desde que comencé a ver sus vídeos y quería fabricarme la extructora pero el link de los planos no me funciona o como debería hacer para descargarlo saludos gracias!!!

  3. Where did you get the heater ffs?
    Can I use my kettle heater…

    Does the controller increase the heat of the heater to about 250°c?…
    Can I use a thermostat controller?

    By the way, what schematic is he talking about?

  4. Hi, dear, Nice video. Lot of thanks.
    Dear from where & how to down load blue prints and what are the specifications for heaters.
    Dear how to calculate the number of heaters to be provided.
    Please do guide.
    Regards & thank once again

  5. if would be cool if you showed your diagrams of welding for more than 1 second so we can see them because the music is telling us to move very fast and not pause.

  6. Thanks man! You are so smooth getting it done, wonder if I can do them as easily as u did. I need something slightly bigger. I need one that can make a 2'' elbow. Can you do it? I hoping to pay for both the extruder and mold. Please let me know what you think.

  7. about..3d printer filament…how does it actually performs?anyone used this in 3d printing? and how precise u can get from this machine?

  8. Sorry am I missing something? In the video it states that the motor specs are in the blueprints. I have downloaded the archive of the plans and in the 3. Build/Extrusion/Blueprint files I only find in the schematic that it should be a "controlable" motor. In the parts list I see that it should be "Around 70 RPM". Is that all the specs? No minimum wattage or HP?

  9. Hola,hay alguno que sepa como se llama cada pieza o material que el usa en el video,porfavor lo agradeceria,Muchas graciaaas

  10. Você é incrível, saiba que aqui em manaus município localizado na amazônia brasil, você tem uma fã.

  11. muito legal adorei sua ideia você é muito bom parabéns eu vi esse vídeo onde você aparece triturando vários tipos de material hoje eu to começando juntar todo tipo de plastico e toda ideia e inovadora a sua é muito legal o vídeo completo do começo ao fim por tanto agora vou juntar mais, também vou fazer uma máquina parecida com a sua se o meu trabalho de certo ai você vai ver ok, a diferença é que eu não tenho o aparato que você tem vou a luta e Deus esta com nós manaus AM Brasil

  12. Really nice video, i want to build something like this and I was wondering if you have any problems with air bubbles trapped in the material and with the fumes that come out from the melting process

  13. Thanks for getting her done and not trying to explain physics and gear ratio and all the other things in the universe great job!

  14. Кто-нибудь из русскоязычных пробовал делать или разбирается в этом? Нужна помощь

  15. Привет! Классный проект! Все реально собрать самому, как говорится руки из нужного места растут.Подскажите где можно купить нагревательные элементы как в видео ? Очень хочется собрать такой же станок!

  16. for people doing this…try to use a coupling, and you can use the same motor and gearbox for the shredder too.

  17. Hi there, I really enjoyed watching this. Quick question regarding those band heating elements: how many watts are we looking at ? My guess is about 50 to 100 watts would be sufficient ?

  18. Man you made my whole day was looking for something to do… after watching your website intro video Its amazing im joining the map. Thank you.

  19. Hello my friend, how are you? Excellent job. I would like to make an extruder the same for a college job. Do you have the step-by-step electrical connections? My friend please. My email is [email protected]

  20. buenas tardes, hola soy de Colombia mi nombre es Reinel puedes ayudarme con los planos para construir la maquina gracias mi correo es [email protected] estoy interesado en construir una extrusora para realizar diferentes productos como postas para encierros gracias y tablas

  21. Tal vez este video pueda ser interesante, una forma fácil de reciclar plástico

  22. In reality, how much would this project take to complete, if you didn't have the tools or shop equipment to produce this machine?

  23. From your developments, i can build all-in-one machine. Shredder -> extruder -> printer. I threw plastic in to the case and after 32 hours the printer do anything that i was needed at home… great scott! 😀 i hope in 2019 you are already do it.


  25. This is cool, i work on large extrusion machines making vinyl window parts, its really amazing seeing this on a smaller scale, it kinda reminds me of our capstock extruders

  26. Струва ми се че солид стейт релетата не се охлаждат достатъчно…

  27. Hay…..its just fantastic…… contain is very clear and easy to understand….lots of information……nice videography as well


  29. Hola Dave, soy Jhonny Millan. Me puedes enviar las características de los componentes electrónicos por favor. me gusto tu trabajo.
