Machines
Make Hydraulic Plastic Shredder
Poly was created to address this sustainability issue while also making recycling more accessible and economically viable. Our system, based on Precious Plastics designs consists of two machines - a shredder that breaks down plastic into small pieces and an injection moulder that takes those pieces, melts them down, and shapes them into new products using interchangeable moulds. Shredding is the first step of recycling plastics. At Poly, we designed this machine to deliver force and be simple enough that anyone can use it. After 8 years of operation, we decided to retire our company and release our machine designs to the public, allowing anyone, anywhere to get started with small-scale plastic recycling for years to come. We wish that you use these designs, create more and help make this world better! Please use these designs and tag us at @enactusottawa on Instagram to share your success!%20--%3e%3csvg%20version='1.1'%20id='Layer_1'%20xmlns='http://www.w3.org/2000/svg'%20xmlns:xlink='http://www.w3.org/1999/xlink'%20x='0px'%20y='0px'%20viewBox='0%200%2044.6%2043.9'%20style='enable-background:new%200%200%2044.6%2043.9;'%20xml:space='preserve'%3e%3cstyle%20type='text/css'%3e%20.st0{fill:%231D1D1B;}%20%3c/style%3e%3ctitle%3eicon%20time%20needed%3c/title%3e%3cg%20id='Calque_1'%3e%3cpath%20class='st0'%20d='M20.5,0.5c-5.8,1.1-11,4.2-14.7,8.7c-3.4,4.3-6.3,11.5-5.7,17.1C1.5,40.9,15,45,27.8,43.6%20c10.3-1.2,17.5-15.5,16.8-25C43.7,7.2,31.9-2.2,20.5,0.5c-1.6,0.4-0.9,2.8,0.7,2.4c11.1-2.6,21.6,7.7,21,18.6%20c-0.3,4.3-1.9,8.4-4.4,11.8c-3.5,4.9-7.2,7.8-13.5,8c-10.6,0.4-22.3-4.4-21.8-17C3.2,13.8,10.8,5,21.1,2.9%20C22.7,2.6,22,0.2,20.5,0.5z'/%3e%3cpath%20class='st0'%20d='M19.9,6.7c0.1,5.2,0.4,10.5,0.9,15.7c0.1,1.6,2.6,1.6,2.5,0c-0.5-5.2-0.8-10.4-0.9-15.7c0-0.7-0.6-1.2-1.2-1.2%20S19.9,6,19.9,6.7z'/%3e%3cpath%20class='st0'%20d='M21.2,23.3c2.1,1.8,4.3,3.4,6.6,4.9c1.4,0.8,2.7-1.4,1.3-2.1c-2.1-1.3-4.2-2.8-6.1-4.5%20C21.7,20.6,20,22.3,21.2,23.3L21.2,23.3z'/%3e%3c/g%3e%3c/svg%3e){kind=small}

Build the Machine
Here are some of the skills and machinery you'll need to have if you’re building this machine yourself! You can also ask someone else to build it for you based on our designs:
- General metalworking (cutting, drilling, filing)
- Welding (steel)
- Laser cutting for metals OR
- Milling (teeth wheel)
- Electrical work
- Motor electrical work (wiring motor, insulation, overload protection…)
- Advanced assembly work (require specific tools, measurement instruments and tolerances knowledge to align and assemble)
- Painting
⚙️ Machinery & Specific tools needed:
- Stone or Electric Grinder
- Band saw
- MIG/MAG or TIG welding
- drill press
- Mill OR
- Laser cutting (You can find a contractor to make the teeth)
Please be advised that these drawing were originally created for internal use only, therefore you are free to make changes as you see fit to your version! We do our best to make these as safe as possible and we advice you to do the same!
