Hi there @chrishollis91 !
Great that you think about recycling these bags!
Basically, PET and PE both can be recycled quite well, However if these plastic types are fused together, it will be impossible seperating and recycling them again. I will actually be in Bristol for two days this week, I’ll drop you a pm!

@anne-barbier yes exactly, we have used band heaters. There are flat heating elements available too, but the ones we found are waaay more expensive (triple or quadruple the price of the band heaters) and that was just way out of budget for us, unfortunately. 🙁

@anne-barbier I think you under-estimate the power of about 3.5kW of heating power combined wirh modern insulation. As stated before we dud tests with up to 180 Degrees Celsius and it worked even better than I expected. It climbed straight up to 180 and stayed there with a tolerance of <1%. Thats good for melting Hdpe, but the higher temperature…[Read more]

Thanks! Our mold Inside is 516mm squared, the outside is 600mm squared. The plastic is 10mm high and the mold is 55mm. The carjack can do 5 tons.
Since we finished building yesterday, as you can imagine, we haven’t made long-term studies yet 😉 so I cannot answer the other questions just yet. The Frame should be able to handle the 5…[Read more]

Update 09.08.2018
WE FINISHED THE MACHINE TODAY!!! we assembled everything after some intense working days with sometimes over 13 hours a day of welding, painting, screwing, buying missing parts, insulating, connecting the electronics and all that stuff.

We also gave it a test run and it worked very well up to 180°C so far! More testng will…[Read more]

@macbeda there aren’t any cad drawings for this machine public yet. If you mean the shredder etc. go to preciousplastic.com

@andyn We will! Already got a device for that, as soon as biggie is finished, we’ll test it!

@xxxolivierxxx you’re right, this is far from optimal! We chose to try this method just because of the cost, we couldn’t find any affordable flat heating elements that fit our needs. Only with cost of 500€+. We will try to make up for that energy efficiency loss with good insulation, let’s see how that works.

@andyn 32 heaters and 110 Watts each.

@ferrash I’ll close this topic. And I moved your other one. @adrienluitot has mentioned everything else already. (Thanks man 😉 )
All the best,
