Machinable wax

I've been using vinamold for making patterns for lost wax...very low shrinkage wax and £4 a kilo...sounds expensive....but that kilo is a lot of wax!

This wax has the feel of plastic when it's cooled...also it shatters when dropped on a hard floor....I need to try to machine some although I have been drilling it and it seems a contender for machinable wax.

I got mine from SRS in Derby Whilst visiting I had the pleasure of a tour and held a Brit award wax pattern

I made about 85 lbs of the wax I mentioned in this post. If anyone wants some let me know.

I joined this forum because of the machinable wax threads. I use it to make tracing stylus molds on my duplicator. What I have found works best is a 'Daisy' or 'Fry Daddy' deep fat fryer by Presto. I melt whatever quantity of paraffin I have at about 325f and add clear LDPE (recycle code 4) from any old source, I've been using the lids from oatmeal containers cut into strips. The none pigmented polyethylene seams to melt easier and combine more readily with the paraffin. Some pigments interfere with the dissolution a great deal, but even simple white talc slows the process. I don't know what my Paraffin/LDPE ratio is for all I've ever done is saturate the paraffin and strain off any undisolved solids. Machinable wax made this way has worked very well for my needs with cutter speeds running from 3400 to 5500rpm with 1/2" and smaller end mills. I get nice clean cuts with no sign of melting. What I've been using for molds are coffee shop paper hot cups. The wax bonds well with them and the paper gives me something get hold of for machining and peals off quite nicely. I'me not sure if this will be of any use to anyone, seeing how I am not tryin g to mold anything from the wax but only cutting my molds into it.
