INJECTION

Since 2016, NoPlasticSunday has been researching and developing machinery and equipment for plastic recycling using Precious Plastic in Korea. In April 2022, we open-sourced our drawings and manuals of the Air press injector v1 for free.

    Let's Make together!

    Follow the drawings and build your own Air Press Injector v1.

    Please feel free use it and share it with others. Any attempts that improves this open source design in any ways are welcome!

    Please share back your experience!

    What were the difficulties you faced while building the machine, and how could you solve it? Did you come up with better ideas for plastic recycling? Please share your results and process. Problems become easier when you share them with each other.

    Run and Share!

    Finally! Have you finished building the machines?

    Please refer to our Air press injection machine manual to get some information about setup and run the machine.

    We hope for more people to join us on the [filtered] movement through open sourcing this plastic recycling technology. Plastics that make our lives convenient but it can quickly became threat to life on earth.

    Let's build a sustainable plastic recycling system.
