Die-drawing Polymers

[Stuggler]

Hi I just had a question, I'm supposed to improve the design of a small-scaled die-drawing apparatus that's designed for a UTM, but I'm having a problem understanding what die drawing is and how it would be used in a UTM since UTM are basically about testing and not producing something. Could anyone explain what die drawing is and why it would be put in a UTM?..... i don't understand it so I'm finding trouble researching other examples to use as reference for my own design

Ordinary drawing apparatus isn't instrumented, so using a Universal Testing Machine would allow the measurement of the forces involved during the drawing process.

oh right but the question I was asking is in terms of a small-scale die-draw (specifically for polymers, not metals) as part of the UTM, would there be any reason to add it to a UTM? (specifically for polymers, not metals)

That would be an excellent question to ask those who are asking you to build it.

Ah thanks, Dave.
