Hi Actually I’m having problems with tick waxes (.4mm) ,and I need
to fix it fast (15 days )

I have seen a lot of vacuum wax injectors in the market, but wich one
is the best?

Yasui? Galloni? Rio Grande? Intellijector? it seems to be the best
it will be?

other option?, I have 8 days to pick a choice and go to buy it, and
where to buy it?

Thanks to all Any help …even a little little help appreciated

Alberto, We’ve been using the Rio Grande vacuum wax injector for
about a year and find it does a wonderful job, expecially on thin
waxes and raised and engraved lettering. Also it seemed to be the
most price-friendly. Jack Van Dell

Hola Alberto!, I have both a Yasui and a Memco Intellijector. The
Intellijector is by far the best and is the “state of the art” unit.
It produces the cleanest waxes most consistantly. John, J.A.Henkel

Hello Alberto, Recently I bought vacuum wax injector. I haven’t enough
experience yet. But I can say to you: usage of the vacuum wax injector
does wax model making rather easier. You needn’t make cuts in the
rubber mold to remove air from rubber. Thin things cast better. But
they don’t cast some time. A surface of the wax model has excellent
quality and copies completely the surface of the rubber mold. I use
silicon wax mold. And the wax model surface has a brilliant finishing
view like the master model surface. I researched a market of the
vacuum wax injector. All injectors were copied from Yasui’s injector
and have the same properties and small differences. I think they have
the same quality of the wax model and different conveniences of work
with them. I found the cheapest variant of the vacuum wax injectors.
It is VM MANUFACTURING CO’s injectors.

Actually, this statement is not true… the germans had vaccuum wax
injector s dating back before 1970’s although they were bigger and had
up to 4 injectio n nozzles so that 4 people could work on 1 machine. I
had one back then and worked quite well. I also have a VM vacuum wax
injector and they do work… however, I have found their injection
nozzle design to be very lacking as they break down easily after a
while and are no fun to repair properly… I’m in the process of
making my own injection nozzle for that machine and will be replacing
the temperature control with something far more accurate.The heating
band around the pot on the inside is small in comparison to the pot
size and gives uneven temperature … if you move the heating band
close to the nozzle location, you will have a more accurate
temperature near the nozzle however, when using low temperatures, the
wax in thetop of the pot will be sluggish unless a wider temperature
band is used.So, As it is… low temperatures are not easily
controlled if you are injecting heavy waxes that require low
temperatures to fill correctly…It is all fixable, but costs money and
time. The best vacuum wax injector that I have used so far has been
the Yasui and is problem free.
