June 2017:
Today we have built the shredder and did a test run. A couple of things still to be tweaked, but overall we managed to get our first batch of shredded plastic.

Thanks to @davehakkens and the team for making this possible.

We would be happy to help anyone who is planning to start building the machines soon with some before-assembly advice.

@ashrak, @jegor-m
Hi
Some Coca Cola bottle still have it… in France for instance.

You say ldpe… So mixture lpde and HDPE is possible? What could be the inconvenient?

Waiting for the next post from Estonia.

@dbougas

Sorry next post is from Finland 😛

Some fast facts about PE

HDPE:
It is stronger and harder than LDPE.
It is more rigid than LDPE.
The density can range from 0.95- .97 g/cm3.
135°C (higher melting point compared to LDPE).

LDPE:
It is less strong and weaker than HDPE.
It is more flexible than HDPE.
The density can range from 0.91-0.94 g/cm3.
115°C (Lower melting point compared to HDPE).

So I guess the melting point temperature would be the most inconvenient..

@ashrak
Finland is also a beautiful country…
Thanks a lot…
Melting at 115′? Is it really so low..

When a cap indicates PE do we have to consider as HDPE?

@dbougas

Yes

from wikipedia;

low-density polyethylene is typically 105 to 115 °C

I think this info exist in an other post, about plastic materials in the forums.
Here is one: https://davehakkens.nl/community/forums/topic/types-of-plastic/

Sorry jegor-m for hijacking your post :S

Thanks a lot…
Yes I remember now this post is really detailed, I have really to store those picture somewhere accessible.

I understand now why my HDPE burned 😋

@ashrak, I am sure @jegor-m works on his next weekly report… And we will be impressed like always!

Waiting for news

🌎Update N.19 – Preparation for TEDxLasmanäe.

Here is a wee teaser of the preparation for a local TEDx event where we have a stand and a mini-exhibition. The story is coming soon.

⚡Update N.20 – TEDxLasnamäe.
Here is our team. We had a great event, met some people with cool new product ideas and talked about plastic waste problem and Precious Plastic movement. Also showed some of our products and even introduced the idea to the president (of our country). It was very quick though, but still! 🔥
Last photo is the back side of the badges we made for the event. Each of them unique as you can imagine and we were asked to make just about 500 of them, not a big deal 😀

This sort of opportunities help to organise the thoughts and reasoning in your head better, so that by the 100th visitor, you already know how to answer any question so that they would have a better understanding of the topic.

🌎Update N.20.2 – #Cooperation within the PP network.

This post will be about preparation for the TEDx event we recently had an exhibition at.
The organisers of the event had some problems with the original badges delivery and 11 days before the event asked PP Estonia whether we can produce 500 badges for them.
We knew it is a risky thing to do, as we had limited resources, but still decided to go for it as the guys said they will help with supplying ovens and volunteers. Sweet.

We decided to ask our friends from PP Vienna to help out as they make cool sheets – exactly what was needed. To cut the long story short, out of 500 badges 190 were to be supplied by them. For those who are not familiar with their products, please visit
Precious Plastic Vienna – Sheets

The guys delivered the cool sheets (photo below) so I would like to thank them for the work done. The problems with delivery don’t matter at all, as they decided to help out, which is more important.

If you ever need plastic sheets – ask @flo-2 and you’ll get them, boom! 🌲♻

@jegor-m @flo-2

Haha this story is awesome !!!

You are crazy to accept an order of 500 pieces but really good move and exempl. Thing if know i have the same i make the same choice becaus you made it !

Hey and just for jokking, badg is not a small thing ? Heart about something like we don’t do small object with P.P. 😉

@geat, as far as I know, the badges we made have the same volume of plastic as in the hexagonal coasters. You can argue that it is a small item, sure, but we would still make it again if needed.
As for the production volume, we had three ovens running simultaneously and the sheet press always busy. We had 6 sets of plates to squeeze the plastic between (which we called molds for some reason) with changeover time to the press every 10 mins.

@jegor-m I just wanted to congratulate you and the team for challenging yourselves and pushing precious plastics further. Great effort!

@plastikfantastik, thanks.
It was a bit surreal to get 500 people in one room on the TEDx event to watch Precious Plastic Promo video by Dave.

🌎Update N.21 – Wall clock
Recently we decided to make some wall clocks like in Dave’s first promo video. The decision was to order a good mould from laser cutting as we definitely couldn’t cut a perfect circle in a plate by ourselves for sure.
After some trial and error and error, we got some product we can show to people.

Material: PP from LUSH Cosmetics
Fabrication time: Roughly 50mins
Thickness: 7mm
Diameter: 245mm
Weight: (250g)

Photo1: wall clock ‘number plates’
Photo2: texture

The cool thing about this material is that it has already been recycled at least once (Lush corporate rule) and that it keeps a nice smell of cosmetics that used to be in contact with it.

@mattia-io,
Yeah, it is 106th of January here in Estonia. We’re just manufacturing, setting up internal structures, getting ready for spring events and getting torn into pieces by people willing to get machine prices from us. Usual stuff, not much eh🙂

🌎Update N.22 – Mess

For those of you who wanted to see how messy our garage is – this is ‘relatively clean’ state. Not much can be otherwise said apart from that we’re building a custom compression machine, photos soon to follow.

*panoramic photo stiched by a trial version of Autopano Giga. Quite a good software, in case anyone asks.

Update N.23 – Still mess

Some compression machine building photos. Of course I had to add a cheeky photo of myself holding the oven door (about 10kg). The magic box we’ve built is going to host a platform like in a regular compression machine. But also in one of the oven configurations it will have a rotomoulding unit inside. It will be a 2-axis rotomoulding thingy, similar to this.

Update N.24 – Great success story

Oh hi there,
Recently we got an aluminium mold from the headquarters, for some time to test and see how it goes. We wanted everyone to know that behind all the fancy looking product photos, there are lots of trials and errors, mistakes and failures.

We got the first two keychains made well and the rest of them, moulded another day, you can see below.

What are we going to do?
Well, melting temp is high enough, no chance of going higher. We’ll try to warm up the mould itself. This will allow slower plastic solidification. Also injection itself should be controlled a bit better.

thanks for posting the errors! I think we had 2 of these moulds and with one we increases the diameter size of the “injection shaft” to make the plastic flow in easier. Not sure which one I send 😅 But that could help? Mould heating definitely helps but is such a hassle to do every time. Also @jerzeek might have some tips on this one!

@jegor-m You could try leaving one of the ‘failures’ in one side (cut it off at the gate) and next time you inject the plastic you will get better flow and pressure into the empty cavity. I agree about the mould heating, not only does it take much longer but also wastes a lot of energy repeatedly heating and cooling the mould.

 

Very nice looking mould by the way!
