I have used the Neutec J2r for nearly six years and love it! We have
gone from casting 1 part a day per flask to 100 pcs. per flask with
nine 4x6 flasks, as big as our kiln can handle. The machine can cast
flasks all day, and I was able to drop sterling silver flasks at the
rate of one 4x6 every 8 minutes. Now that is fast!
The crucible heats up the metal quickly and evenly and the vacuum
draws the metal into the perforated flasks quickly with very few
non-fills or partial fills. Due the the power of the vacuum, I have
had a few blow-outs due my error, either mixing a bad investment
ratio or sprucing parts too close to the top of the tree.
The flexibility to switch flask sizes mid-casting, and crucibles (if
you have the cooling container) makes this casting machine an
absolute dream as it works so efficiently.
The only maintainence I have had with the machine were the
consumables, if you consider that maintainence. It is expected that
one will have to replace them as they are worn out and used.
I would highly recommend the J2r or any Neutec product for that
matter - the sales and service dept. at Neutec/Rio Grande is second
to none, in my opinion.
