Hello @khebizi

PET is known for being pretty hard to shred. My guess is that your shredder blades are no longer sharp and the edges of the knives got rounded. Plus, if the blades get too hot after running for an extended period of time, the heat will cause the plastic to bend instead of being cut.

My advice would be:

#1 – Let the shredder rest for a few min between shredding cycles to let the blades cool off

#2 – Dissasemble the shredder and grind the edge of all knives to make a 30° cutting edge, that way the shredder will cut easier through plastic. There was a tutorial somewhere around the forum with pictures of the end result but I can’t find it right now

@eltonmcj they look pretty good, although finding the gear reducer will be the most difficult part.

@snowcode seems it looks like you are not very familiar with all the processes involved in filament extrusion, I suggest you to have a look at Werbewunder’s youtube channel, that will give you a better idea of what’s involved

@jewie104
Understood, just keep in mind that building the machines is not like playing with lego, you need to have knowledge on welding, metalworking, power tools, and if you are in charge of the camp, you will need to be accountable for any accidents (hope that never happens) that might occur if unskilled people get hurt during the build process.

Please have a look at the Precious Plastic Map, that’s the best place to find people near you who is willing to cooperate 🙂

@v-d-s
You will have a pretty bad time trying to take your parts out of the wood mold without destroying the parts, or the mold.
You could try curing the wood with oil, or applying a layer of epoxy resin, but molten plastic might end up sticking to the resin or the quality could be affected by the oil in the wood.

@nkhwazi It pays off if you can make a product that has local demand.
For instance, it makes no sense to make spinning tops that kids don’t want, and that you would have to sell at a super high price to try to pay off your invesment, and it would not make sense either to make iphone X cases if your goal market is a rural place or full of people who only has Android phones.

In summary, you need to define your market first, then find a product that people needs and is willing to buy, then finally think about how to mass produce that product.

Hello @jewie104
Did you already obtain all the parts needed to build the machines or is that still pending? If you haven’t obtained any parts yet, I would recommend buying the machines from our Bazar
I would also recommend getting a dual axle shredder, or wait for the V4 shredder to be released this month.

Hello @spencers0
I think the V3 shredder can shred 1/4″ plastic, but it would be pushing it too hard, I suggest to look for the V4 shredder or a semi-industrial shredder like https://www.amazon.com/INTBUYING-M%C3%A1quina-triturar-pl%C3%A1stico-resistente/dp/B07QF7ZF7R

Then you can sell your shredder plastic on the bazar or in injection molding groups like https://www.facebook.com/groups/2206675146227501/

Haven’t seen anyone mention it yet, but TPU and Silicone are perfect for sex toys 😉
Plus I don’t see anyone making these products yet in the bazar, and making moulds should be pretty easy with a 3D printer and plaster, so it would be a good business opportunity.

@davehakkens you know what might be wrong with Sagar’s account?
I logged in with his credentials and can’t create any topic, but his account doesn’t seem to have anything wrong.

Just sent you a PM with his current credentials in case you want to test.

Also, on regards of the new V4 machine, the files this time should be less complex and use the same steel thickness for all parts, so you could make the parts yourself with an angle grinder and/or a vertical band saw. I’ll try that myself to avoid spending more money on laser cutting.

Your ID isn’t banned, not sure why you had problems with your old ID.
I just sent you a private message with a new password, try that and let me know. I tested your new credentials before sending them and I can login just fine.

@btmetz
Leaving one side of the mold fixed to the extruder is a great idea, and the other part of the mold could be attached to a hidraulic piston to automate the opening/closing of the mold 🙂
Have you tested this design already?

@pablosaker1 If you used a different metal thickness, you also had to enlarge the side panels of the shredder because when you add up the thickness all of the rotating knives and spacers, the total length won’t match with the side panels
