Experience is also key when selecting the type of plastic to be used. In addition to the many selection factors listed in the article, there are also unique features of each polymer group that need to be carefully considered. For example, Nylons can be hygroscopic (take up and retain moisture), while Polycarbonates should avoid exposure to excessive radial stress. Its a smart move to also find a plastics expert and leverage off their years of experience as much as possible.
Thanks for this overview of injection molding, a broadly capable set of technologies the the modern world can't do without. I was especially interested to find out how much it's used in the earlier design stages for prototyping, as well as for final production.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
