overmoulding info?

am trying to develop a “rubber” product that may need some internal stiffening/structure. The product is very simple but the material (as yet undecided) would be very specific in terms of durometer, and “feel”. Can someone give me some pointers on how I might approach this problem? I will be seeking some professional assistance, but I was wondering if there might be a good source/s of information availiable that I could read up on. thx.

IDFuel’s last Tech Thursday covers overmolding basics, and it’s a place you can get started with some understanding. Check it out at :
