Precious Plastic – create things from plastic

Welcome to a new Precious Plastic video In the previous video, we learnt all about plastic, we built our own machines and we collected the material and now it’s time to create new things. So, first we are going to talk a little about different melting temperatures of the plastic. Then, we are gonna talk about mold making, how to make your own molds and where to look out for. And then we are gonna create objects from plastic waste. Let’s go! When you heat up plastic it melts, but every type of plastic melts at a different temperature. Now, you can easily look up the melting temperature alone but this is just a number and it doesn’t really say much. We wanted to make it to more visual for you guys. So, we did a lot of different melting temperature experiments and made research. So, each row is a different type of plastic and here it is 120° and here it is 218°. And as you can see, some plastics start to melt at lower temperature while others need much higher temperature to melt. And also some materials have a very long melting zone, while others are quite crucial and you need to have the temperature quite accurate in order to have it melt properly. Otherwise, it burns. And this is a usual reference when you start working with plastic to see what it does at what temperature. So for instance, we can see what Polystyrene does at 200°. I have turned this in a poster which you can download and print to put in your workspace, or just watch it. Overall, the principle of working with plastic is that you heat it up, you mold it and then you have it cool down. You can shape plastic in almost any form when it’s molten. However, for production, it’s better to work with the molds, because you can easily replicate. So metal is a good material because the plastic doesn’t stick to it and if it does, you can scrape it off. Next to that, it is durable and it can withstand the heat. Now, our machines work with a whole variety of molds. You can CNC them, you can weld or make them on the lathe. It doesn’t really matter that much which technique you use, but the more accurate you make your molds, the more accurate your output which is quite nice because if you put a lot of effort in your mold once you can easily replicate more products. So prototype around with different kinds of molds but make sure your final one is accurate and well made. So now we’re going to test a few molds in the machines. First thing we do is we’re gonna select which type of plastic we’re gonna use. And personally, we like to use ABS, Polypropylene and Polyethylene because we can easily find them around and they are pretty easy to mold into something new. So, the first step is we’re gonna shred it. Here we have the injection machine and for this machine we have several different molds. So for instance, we use this one, it’s a CNC milled block aluminum and this is nice. However, it is quite an expensive technique to use. So we also made one using the lathes. This is actually the technique we used to make the spinning toy molds. And this is quite easy to do and affordable. Or you make them from some steel and weld it all together. So, let’s try this one out. We’re gonna make a handle. Plastics. You can tell that it’s done when you can’t press anymore. Then it should be good. So, now we used a red and white mixture of different colors but as you can imagine, using different colors or separating them you can also make them solid black or blue or create these marble like textures In the extrusion machine you can throw a lot of mixed colors and the nice thing is that it turns around and it blends everything together so you get one nice solid color coming out. It’s quite hot! For instance, here we started off with blue and white and slowly added more red. So you can create nice gradients and you
can use it to create new raw material. You could chop it and turn it into new
granulate. Use it to weave something new like this hat, or you can spin it around the tools to create handle bars or get really creative and put a mold over
here where you can turn it around. I mean with just a single line of
plastic you can do a whole lot. The compression machine basically
compresses two plates together. Now, if you’re going to add some plastic
in between it squeezes it together so we create these plastic sheets and obviously we can play around with colors and mix them and blend them together to create something spacey or.. not. But we can also get more three dimensional, for instance by adding a texture. But we can even make it more three-dimensional by making more three dimensional molds. This one is from this fruit bowl we make. This way we can create these nice little bowls and containers. Another cool thing is that you can also
make more solid objects and super strong! Now in itself this isn’t really useful but if you look at this like wood and use conventional tooling you can create a lot of new things with it. Obviously there’s much more possible
with these machines and we barely made a few examples so we would love to see what you can come up with. So if you made something please share it, and if you have any
questions feel free to post the topic in our forums. Alright so that’s it for now. I wish you
the very best of luck making things and have fun recycling!

  1. que fantástica maquina ayudaria a descontaminar el oceano, vertederos, plazas, campos, montañas etc etc con solo reciclar el plactico ……. amigo como o cuanto vale una maquina o como se pueda adquirir asi uufffff quede impresionado ….gracias

  2. Hi, I'm Freddy M. I'm a big fan of protection for the environment. I'm knocking on doors in my country to be able to start. I developed a system that includes all inorganic waste at once, called paper, cardboard, plastics, glass, metal, wood, rubber, cloth, and others. I would like to have more communication with you, I would like to leave to be with you … A thousand thanks for existing Precius Plastic.

  3. I doubt i'd ever get into doing this but there are a few things i'd love to make if i did: one idea you guys (or someone) might make use of is the frame work to canvases for painters (or easel stand). The normal material is wood.

  4. There is a recycling crisis coming fast … China does not want to buy our garbage any more … bales of plastic paper and other waste are stating to accumulate … this has created a BILION DOLLAR oppurtunity for smart young people … if yo could scale up some of your machines 18 Wheeler size you could drive town to town Like local Farmers markets … Some will bring stuff to recycle some will want the recycled new raw materials … In my 70 yrs … We burned our garbage … we created garbage mountains put grass on top and made play grounds … then we started shipping it to China … With Youtube has come an acceleration in the DIY industry and they will need raw materials

  5. Dave this is clever, absolutely fantastic.. bravo! Can you make eyewear frames with recycled plastic? Considering you have to mount lenses and bend it to fit it good on your face..

  6. Very interesting, but what can you share about any toxic or harmful gases you may get exposed to working with and melting plastics?

  7. Hi, is it possible to create so many "bricks" like Lego, (but bigger) so that anyone can build easily other things, such as wall, little houses, etc…
    What is the right material to use?
    Sorry for my bad English.

  8. Genial 👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏😘

  9. ello greetings from the uk first id like to comend u in ur work to help the enviroment and recycle as well as sharing ur knowledge in how we can do this ourselves. as im a builder and work in the construction industry im very much intersted in finding working with recycled n eco friendly materials designs and construction methods. so id like to ask if u can create n show how to make interlocking building blocks like wat anova designer architech company oscar mendez of conceptos plasticos has done check out his video on youtube. it wud be great if u can so this as i think not enough is being done to use this knowledge material etc in the construction industry and fight for recycling. thanks and keep up the great work!

  10. I am 13 years old and in 7th grade. I have a plan to pick up all of the plastic from the ground at my school, then make rings and stuff to sell to show kids what you can do with litter. Wish me luck!

  11. Wow. That is wonderful idea! Every day I pick up so many trash plastic bottle, plastic buckets, plastic containers. Now your idea is great. Can I do your idea at home? I don’t have this many tools. Thank you for sharing!

  12. What an amazing person! Sharing his wisdom with others. More people like him will make our planet as a whole better for many generations to come. Much love!💖💐😊👌

  13. This makes me want to become an engineer. I just graduated college but if I had the choice to start all over, I’ll choose a career in making cool stuff like this from recycled materials. Very inspirational 🙌🏻

  14. I am so glad that your channel exist. I am working with plastics on a larger scale and your videos are very informative.

  15. Breathing baking plastic fumes can be harmful for you. If you have lung, liver disease, or other such ailments, I would suggest a different hobby.

  16. But remember, melting plastics will produce fumes which can be harmful if inhaled. Make sure to melt them in a well ventilated area.

  17. These machines you have created are incredible! Precious Plastics has amazing potential to make use of unnecessary plastics! I can't wait to create projects with this:)

  18. Everyone is making hdpe blocks or discs but no one has made a mould for a larger size part where the plastic doesnt stick. let me know how if anyone knows.

  19. I'll 'like' this video just for the fact that you took the effort to show what different temperature does to Plastics, instead of just showing a diagram. It was good to see people go the extra mile

  20. I make felling wedges from HDPE.
