Hi All -
We produce specialty epoxy compounds used as adhesives, potting compounds and coatings for specific OEM applications. We presently mold parts for mechanical, thermal and electrical testing , and while that works for more liquid systems, the thicker, more highly-filled systems can be difficult to prepare Obviously, sample prep is critical for accurate results in specific thermal conductivity and mechanical testing and we’ve reached our limit in the molding/cutting/sanding process of producing parts for specific tests. That has lead us to recently discussed getting a small CNC machine for the lab to look at perhaps machining the parts to replace the molding/cutting/sanding process.
One caveat - our materials may be highly filled with a variety of abrasive materials depending upon the properties required, so, if we go the CNC route, we’d need the right cutting and milling substrates.
In general, we would not be making ‘pretty’ parts, i.e., not complex at all. For example, one ASTM test for three point bend requires a part that is 1"x4"x0.225". Another would be a ‘dogbone’ sample per ASTM D638 Type 2. The key for us would be to produce parts accurately and reproducibly,
Is there someone we can/should talk to about our questions/concerns? The Nomad 833 struck us as a good starting point, but at the end of the day, we’re really good chemists, good material scientists, so-so mechanical engineers and really bad graphic designers…
Thanks!
