HDPE block stock can be made from recycled plastic milk bottles (recycle code 4) melted in a domestic oven at around 230 degrees C.

I have tried a few processes with variable success: -

  • initial tests using the Hackspace reflow toaster oven at 220-230 C
  • some fun with (cheap?) silicone cookware that breaks down at cooking temperatures!
  • slight fumes but not unpleasant or dangerous - appropriate ventilation employed

Further tests at home in domestic oven: -

  • cleaner process - using baking tray and baking parchment
  • pressing into a plywood mould to make "slugs" for milling
