How does the Shredder pro by WEIMA behaves

We are going to test the new Shredder pro by WEIMA shredding different plastics. We will explore the differences between the several plastic types as well as the many formats they come in, from pipes, to fishing nets, to jerry cans, PET bottles and more. We are open for suggestions! What would you like to see us shredding? If you want to see the machine running, check this video https://youtu.be/IkstKYp7wNk?si=bNKfvXhwUStqno8z

Testing old LDPE water pipes

Created 7 months agoUpdated 7 months ago

We received an old water pipe directly from Project Kamp! This pipe was buried under the ground for many years, now that it was too old an full of holes, it needed a replacement, but we couldn't just throw it away! So we wondered, why not try to make something valuable out of it? 🙌 So, we did our first tests with this pipe to see the capabilities of the Shredder Pro by WEIMA. Initially, we put in the full pipe to see what would happen (find video attached to this update) and the machine jammed fairly quickly, that's because this tube was about 5 mm thick and made out of PE, which it's a very strong material and actually, we would even dare to say that in general it's within the hardest plastics to shred, since its very flexible and not brittle at all. But after a few back and forth we managed to shred it completely with no problems. In general, for better efficiency, in the future, we would recommend to cut it in both length and width way to reduce the thickness the machine takes at once.

PP water pipes

Created 7 months ago

This time we tried a different kind of water pipe, this time it was PP. As expected it was easier to shred than the LDPE ones from the previous update, since this is a material that even though its flexible, it breaks much easier than PE. Also the fact that these were much thinner (~1-2mm) also helped for the shredding part and we didn't have to chopped them before putting them in the machine, which saved us quite some time as well.

Mixed LDPE pipes

Created 7 months agoUpdated 7 months ago

Now we tried again some LDPE pipes, but this time there were all different diameters (20-200mm), lengths and thicknesses (2- 5mm), so the way the machine was going to behave was going to highly depend on the format of the tube itself, even if they were all made with the same material. As we learned in the first update, PE in general is a hard material to shred, its very tough. So we expected the large and thick tubes to be the hardest to shred, which was it the case. The larger the diameter, most of the cases, the thicker the tube, and therefore the hardest was to shred, so we had to chop them into smaller pieces of around 100 mm each. Sometimes it the machine jammed (even when they were chopped), but with a few back and forths it was enough to unjam it.

Video update

Created 7 months agoUpdated 7 months ago

Precious Plastic made a nice video where you can see how we shredded the Project Kamp pipe plus the other two pipes mentioned in update 2 and 3, as well you'll be able to see the process of transforming the PK pipe into something new! ✨ Go check it out :)
