I finally bought a motor.
Got this one : https://www.motorcontrolwarehouse.co.uk/tec-worm-gearmotor-2-2kw-20-to-1-1.html
It has a 35mm output shaft with keyway and I’m wondering how to connect it to the shredder shaft.
Is it a good idea to turn the 35mm shaft down to 20mm and buy a 20mm coupling bit?
Or should I try and manufacture myself a 35mm to 20mm coupling?
Thank you for your answers
I’ve just received delivery of the shredder laserparts. Excited to get started with the build!
I’m looking for motors at the moment and I found this one on ebay
I’m not knowledgeable at all and I’m wondering what the “hollow bore” means.
Will I be able to put the hex shaft straight into there? (Once turned to the correct dimension?) Or do I need to find another shaft and some sort of coupler?
There is another motor with a 25mm hollow bore, is that preferable?
Thanks for your help!

i am making the compression machine and i’d like to get it more automated
i am looking into arduinos modules.
so it would be :
-1 arduino uno
-1 max6675 module to get the temperature
-1 dual bridge l298n to command 2 electric cylinders.
-2 electric cylinders
-no cold start of motors before t° has reach 200°
-upper limit switch when 2 moulds are touching each other
-lower limit switch
has it been ever tested ? anyone in the team happy to help me with arduino programmig ?
What works better or/and cheaper?
I have a powerful motor 8,5kw all set and ready to shred but I still need to reduce rotation speed.
Can anyone help me with that?
Separate gear boxes cost a lot (better to buy them together with a motor)
I lean more towards changing frequency but I need some drawings and general market knowledge.
Hey guys and girls!
I am brand new in the community and i was thinking about to combine the shredder and extruder together with one motor so you need much less materials and have a 2 in 1 machine!!!!
For explanation you connect the 2 machines on the same motor or wave!
Does anybody of you tried out these method?
Id like to say thank you for such a nice project! Its fantastic!!!!!
I am traveling right now threw indonesia and see everyday tons of plastic lieing arround or burned on the street!!!! I think THESE project is a big step forward to become plastic precious!!!!
What does the output speed affect on Extrusion Machine, How much should the output speed be for the average machine? I mean, Precious Plastic’s website says an output speed of 40-140. When it’s 40, what purpose can we use it for? When it’s 140, what purpose can we us it for? We talked with those who make the machine with output speed around 70-80, but if our supplier gives us an engine with 140 output speede what happens?
I’ve been following Precious Plastic for about a year now and I have to say, it’s a wonderful project! One, I’d like to contribute to at some point. Currently, I’m in my last year of industrial design studies and I’ll start soon my Bachelors Thesis on designing a 3D-printable monocoque frame for an electric scooter.
I’m planning to actually print & test the frame next spring/summer. As my primary tool I will use my Hangprinter, that I’ve been developing the past 1.5 years. The Hangprinter is a frameless printer-concept by Torbjorn Ludvigsen. The printer consists of a base unit with all the electronics and motion mechanics, and three anchor points on ground level for dyneema lines, which are used to position the print head. It is a quite unique concept, but foremost it is easily scalable to (theoretically) any size needed by only extending the lines.
My printer has currently a 2.5 m tall tetrahedron frame, a heated print surface and the e3d-online SuperVolcano filament extruder attached to it. I did this summer two big print projects on it. One was a giant high heel for a finnish shoe designer and for the other project we printed the shell parts of a prototype robot. What I learned, was that the current FDM-technology is far too slow for a printer this big and of course that in long term it is not viable to print anything else than waste plastic.
This is also the reason, I’ve been interested in Precious Plastic. You guys have come up with nice machinery for shredding and extruding plastics. If you want to print with waste plastic, the first step is to shred it. My initial thought was to make my own filament, but after second thoughts I realized, that it is just a unnecessary step. So, I began to study commercial pellet extruders and their open source counterparts. Finally, I designed my own extruder and I’m now in short time getting it ready for testing.
Tech specs are as followed:
Effective screw length: 225mm
Heating: 3 x 180W /230V
First, I’m going to test commercially available recycled HDPE and PP pellets in order to rule out issues caused by raw material impurities and quality, but eventually my plan is to test shredded flakes.
I know that both HDPE and PP are going to be really tough to print due to their heavy warping properties. That is something, that can possibly be addressed only by a controlled heat chamber. But before that is going to be on my todo list, my idea is to mix chopped carbon fibers into the polymer. Fiber-enhanced polymers usually print nicely, since the warping is mostly eliminated. I’m hoping this will be the case also with HDPE and PP.
The printer frame is going to need an update to be able to handle the stress caused by the pellet extruder. I already have a new set of BLDC-motors with rotary encoders, that will do the heavy lifting. Each of them is rated with 1.8kW and there will be 4 of them in total. Also new Dyneema line is on the way. A single line will be able to lift around 140kg. The whole system runs on a Duet 2 Wifi controller and ODrive BDLC-driverboards.
So, what do think? Do you have any questions, feedback, etc.? Do you think this setup could be beneficial for Precious Plastic?
