I have been working with a local high school over the last few months building the extrusion machine. My portion has been to modify the resistive heating system into an inductive heating system.
In theory this will allow for a more efficient system and potentially easier to source although the last is dependent on how much salvage you’re willing to do.
In addition I have experimented with a single heating coil with progressively spaced coils so that one coil could have two heating zones.
I am wrapping up the project and will share all my designs and data in the coming weeks but was hoping to hear thoughts from the community for my final presentation(this was a capstone project for my EET degree).
I did a couple searches but did not see any other inductive heating versions so if anyone knows of one I’d be interested in hearing about that too!
Thanks for everyone’s effort into this project!
