I am thinking about purchasing a vacuum wax injector for production
casting in the very near future. The main reason I am considering
this is because some of the designs that I plan to put into
production are similar in dimension to dog tags i.e. (wide and flat
approx. 40 mm by 20 mm by 1.5 mm with a raised border and lettering).
I am currently using a small wax injector and I am having problems
with incomplete fills on the lettering.
I was wondering if anyone on the forum is familiar with vacuum wax
injectors like the one that Rio Grande sells.
I would also appreciate some advice on injecting wide flat pieces.
Generally I cut vents into my molds and use westcast aqua injection
wax. I am pretty happy with the results I get on most of the pieces
I’m working with, it is just the flat waxes that seem to be a
problem. Thanks in advance.
