Plastic extruder

this is probably V1.0.

intent: To build a small extruder capable of melting thermoplastics for the purpose of recycling used containers into usuable new material.

history: its based on a bunch extruders i have been checking out the last 6 years. originally i thought i would make filament but now i am ghinking of making pellets for molds.

current:

still to do: build hopper. lathe bearing mount. drill out nozzle. motor mount. install timing belt and motir. build control box. install heating bands. weld barrel.

doing some more control box work.
upgrade the hopper funnel to accept aluminum angle as a mounting baracket
welded up the hopper (no picture do to embarrassing booger welds)

little bit by little bit the extruder progresses. hope to be done soon. would like to have my kitchen island back.

Are you gonna heat the extruder shaft or are you relying on pressure ?

Cool build

this version has PID controlled heater bands.I’m just using a 1" auger bit right now but i have thoughts of setting up a 4th access on the Girzzly and machine a proper extruder auger. But thats wayyyyy down the priority list
