RE: RT part strengths

We have an undergraduate student here at De Montfort University, England
trying to evaluate the comparative tensile strength of resultant ABS and PP
injection moulded parts from Aluminium and AIM tooling. I think he's due to
finish this around April time.
I also provide an attachment of references of relevant papers which I hope
will be useful to you.
Good Luck, Regards Russ

Subject: RT part strengths

I am a student at the University of Utah doing thesis work on the material
properties of injection molded plastic parts made using Rapid Tooling. I
am using five mold insert sets; tool steel, aluminum, Ciba, Albright, and
AIM. All insert sets have the same geometry. The parts will be tested
for tensile strength and impact resistance. I have a couple of questions.

1. Does anyone on the list know of part strength issues companies have
had going from RT to standard molding methods?

2. So far I have found only one similar project by Colton and Starr at
Georgia Tech. If anyone has come across related research would you please
drop me a line
