yeah, us materials people will be in there too - since you have to design the mold, the polymer, and determine the properties you want after injection molding
example - if you do an injection molding of a monitor frame with only a single point, you will have a large residual stress closest to the injection site, while the farthest points will be the most stress-free.
this means that you'll have a much higher chance of the frame breaking at the injection site. multiple injection points can be used at lower pressures to reduce residual stress, injection time, etc, but then you run into troubles at the points were the flow fronts of two injection points meet (i can't remember what it's called)
materials is a lot more than just properties - it's processing as well

I worked as en EE for GE in their consumer electronics division.
The way we worked was marketing told us what they wanted.
The optics guys told us what was needed to produce the results, how bright a crt was needed, like for a projection tv.
Then we , the EE figured out how to make it possible.
Its sent to the optics guys. they review, comes back to us, we make changes, back to them, rinse , repeat.
Marketing reviews, tells us, that is too expensive, cut corners somewhere, we make changes, the whole cycle repeats.

Material Science I was a breeze for me. Is II a lot harder?
I used to work in a small company that was run by a PhD in optical engineering from MIT. So yeah, there are optical engineers.

Good to know. I was just going by the class description I'm enrolled in for next fall.

Materials Science I probably deals with mechanical properties of materials, and MSII is probably electrical properties.Originally posted by: CraKaJaX

I'm an EE and had to take an electronic materials class. Oddly enough, though, only like half the class was electrical properties of materials. We spent a lot of time looking at hardness and tensile strength, which seems more like ME stuff to me, but whatever.

Yea, that's what ours basically is (Mat Sci I), not sure about Mat Sci II. How were those classes for you if I might ask? I've been told it's "physics meets chemistry" .. I might have to shoot you a PM

I did alright in my materials science class, but I think it was mainly because my teacher was pretty easy. Don't know how much help I can be, but if you ever have any questions feel free to PM me and I'll do my best.
Mechanics, E and M, Quantum, Calc I, II, III, ODE, Math Analysis
Gen chem/mse
A few other eng. class (electronics, a little bit of mechE, etc.)
And lots of core classes (OPTI)
We are also required to have a focus (I'm doing materials (MSE)).

My cousin was an EE and she is getting her doctorate at MIT working with the professor who essentially invented the necessary technology to get OLED working. She is now working with him on a new display technology that is related. Pretty neat stuff.
product design is one possibility, it used to be part of the mechanical engineering
program at Stanford.
you can get into a "team member" position via a mechanical engineering or
electrical engineering or physics degree.
then it's a matter of learning the specialty issues associated with the company
and the technology, kissing @$$, climbing the corporate ladder, etc.

Industrial design is not the same as industrial engineer.
Industrial engineering as a major focuses on quality and you will likely get a job as a quality engineer.
