What is Micro-Molding?

There seems to be a lot of talk these days about micro-molding. This reflects the increased interest from designers and manufacturers in producing and procuring high precision, micro-featured plastic parts. The result has been countless articles in the trade magazines addressing this new niche in the injection molding industry containing many differing definitions, creating some confusion. So exactly what is micro-molding?

Part size is one of the obvious elements but is it the only element? Or is it simply defined by the size of the injection press? What about precision, or does the part just have to be small?
