Well remember to clean your plastic!
Even companies who also mixes plastics are washing their materials, as you newer know the toxidity dangers of what is being mixed.
This will also affect your outcome, as @clementhempel also says.
Try only to mix your material if you have to. Like when recykling products that is made of parts from different types of plastic, BUT SORT THE PLASTIC WHEN YOU CAN!
The plastic you are fusing can not be recykled again easily, and you will not help the envioment that much.

Please do alot of research before going on with this

Good luck

Mathias

Looks solid, i have ben thinking about making somerhing similar. Just made in 100% Plastic. I like how you want to make a metal frame and then fill in the plastic sheets.
With the right oven, or right hydrolic press, or heat press, it should be doable.

– best of luck

Real great questions @lisacole, i am sorry that i cant anser all of your questions. I am not yet a user of the machines, but are cooking some plastic in an oven for then to be used as raw material with woodworking tools. I dont think i am helping the envioment by turning 2 kg of plastic waste into products every month.

In various countries it is forbitten to sell products to be used with food, that is made from recycled plastic. It has something to do with the deteriation of the plastic, and that the consumer cant know where you got your plastic from, and that it might have conterminates from the place it was used last. I would have it as a rule of thump to keep recycled plastic and food separated, even for yourself. The recycled plastic is not dangerus, but not 100% healthy to eat from either.

Good luck – Anris

Please stick to one topic, discussing one topic…
When posting more topics with just one line of text, AND the same genre, you are just making spam.
Its okay to ask questions and trying to make good conversations, or sharing your stuf that you are proud of, but this is not even a understandable sentence.

Well good luck with the Production!
I think many members inhere are looking at the plastic as more of an hobby, and making smallere items. Maybe you can find someone who is more Up your alley 😉

Best of luck!

How much money are you going to invest?
How many containers are you going to make?
What do you want us to say? That thing is huge!
How do you want to tackle this, i simply need to know. And still, you need lots of gear and MUCH more then the precius plastic machines to make this projekt..

Please tell me @alekpero or else i cant help you…

No, the air from a heat gun is super bad at heating up the plastic..
Some types of plastic will get soft or kinda molten, but it is very hard to make it stick together.

Use an oven, a toaster or some of Daves machines.

Good luck @joshy 🙂

@alekpero
Try and make a mold out of iron.
You need 2 “iron dumpsters” one have to be smaller then the other one
Then you need to melt some plastic inside an oven, i prefer PP (5) or HDPE (2)
Place the molten plastic in the bigger “iron dumpster
And mash the smaller one on top, like on the picture below.

Let it cool a bit and the plastic garbage container will come off.
(the plastic is all the colorfull things going on as i normaly use all kinds of plastic resurces)

Guys, do your research before playing around with PET, it is VERY hard to recycle.. It has to go through a very precise heating process, were you have to hit around 260 c’ with a maximum of 2 c’ of error…
If this is not done, the PET will get super hard and crumble or burn (as you also said this is not healthy)

And what is that thing about mixing sawing cuttings into the mix? That does not seem freindly to the environment, or further recykle.. @blackcatkuro

I am just incorraging you to do proper preperrations.. I am no expert but i know that PET is one hell of an material to work with 😉

It may be possible to make it from PET bottles if you cut them to make some rope and then knit it together to make kinda like a basket.

PET is very hard to melt so i would not recomment that.

Go with PP or HDPE if you want to melt the plastic into a “trashcan-mold”

Good luck 🙂

Hey thank you @armbouhali !
I have not seen this topic before, but you are spot on..
The earrings and other fashion accessories are matching the bracelet and ring i made in that previous topic:

@btmetz the idea is fine, and i am pretty sure it is possible, so you just go ahead and try it! Would love to see it done 😉

We just do not have such a soldering iron, and the heating with a heat gun, or a torch works just fine 🙂

All the handles

Are working just fine, as they are quite solid and they do not get hot when heating the coins
(picture one)

We gave them a little sanding
(picture two)

And the HDPE coin got a wooden handle as we use this coin a lot

Solding the iron rods to the coins

After the supposed plating were removed, it were then possible to start solding the iron rods to the coins

We got an interim setup up and running that looked like this
(picture one)

It consisted of the coin, then a few cut off silver bits, with some flux (picture two) on top and then the iron rod.

It was then possible to melt the silver and make it bond the rod to the coin.

Hey, thanks for the questions @andyn

Our first impression were that the coins were brass plated steel. As the coin would be totally silver when the plating were removed.
(picture below)

But when i try testing for any magnetic response, there seems to be none. Implying that it might be 100% brass after all.

We have found that the method of stamping depends on the type of plastic you want to stamp:

HDPE [2] takes more heat and time to melt before the stamp makes a nice clean mark. Therefore we found that leaving the stamp on the plastic till it is cooled down, works best here.

PP [5] is melted by the heat fairly fast, making the prosses of removing the coin straight away the far superior here.

Burning the coating

– took about a minute for each coin, and it were easy to tell when the coating were burned as the coin would turn black, and give of a bit of smoke.
(picture one and two)

The black marks could then be scratched of fast and with ease

The second issue

Were a bit harder
The plan were to sold some iron rods to the back of the coins to act like handels, so that the coins were easy to operate.
(picture one)

But the coins were coated in a layer of brass that we had to get rid of.
First we tried to scratch it of.
(picture two)

The scratching took a lot of time and effort, so we decided to burn of the coating with a torch.

The first issue

Was easy to take care of.
We marked the top of the coins with a marker
(picture one)

– and used a file to leave a visable mark in the back, to indicate the top point of the coin.

@dbougas
This gift challenge sure is a nice initiativ.
But i am afraid that the time and postal fee is a bit much to ask for all of us to do. It would be more easy to do if all of us lived in the same country.

Keep up your great ideas, this time i have to pass sorry 🙂

Thanks @armbouhali !
The gem idea is great, i will try that for next time

The color blend and shapes are completely random, and can only be controled by how big your granulate is, and how much you twist the plastic dough before making it into a sheet 🙂

@dbougas asked for a comment from my girlfriend, she says that it were a nice gift, becourse alot of time went into it, and the ring were in her favorite color.
