Plastic Granules

If you can't, then searching the usual source for "HDPE rods" throws up an alternative, neatly chopped up in 2 dimensions. Given a shear, the third dimension should be relatively quick for small quantities...

Failing that...

If you want to mould it you could try the regrinders who will be more flexible than the virgin suppliers an alternative is to ask some one who is moulding it and try and scrounge half a bag.

No I'm making machineable wax, but no doubt reground would be perfectly adequate as I'm using plastic milk bottles at the moment !

How are you making machineable wax out of HDPE? What's the process? Is it fairly easy? Thanks, Eric

I have cast and machined candle wax with some success, the secret is to put it in the 'fridge to harden it. Peter

Melt candle wax, raise temperature to about 130 degC, stir in LDPE/MDPE / HDPE pour into mould

1 part plastic 4 parts candle wax (I actually put 10% styrene in the wax first though not essential) Takes a long time for the plastic to dissolve, and the greater the surface area to volume ratio of the plastic the quicker it will dissolve. I've been using cut up plastic milk bottles. Make sure you don't overheat the melt or it will burst into flames. Absolute tops is 190 degC. Use an ir thermometer frequently. Deep fat fryer is the easiest pot but get one with the elements on the outside of the pan not the inside.

Does it make good chips too?

Very chewy with a slight Kipper tang

Thanks for the info Andrew. I'm going to try making my own. Probably save a few cutters from destruction. Eric
