News that GE wants to sell its plastics business is of interest to design engineers. In the past 25 years, engineering plastics suppliers, led in part by GE Plastics, have been important developers of exciting new designs for plastics, such as instrument panels and various business machinery. Rising raw materials costs (oil-related, primarily) have reduced the profitability of the business and made it a weak performer for high-flying GE. This was surely a tough pill for the company to swallow because famous CEO Jack Welch cut his teeth at GE plastics after graduation as a chemical engineer from the University of Massachusetts.
One personal anecdote shows the role GE Plastics has played in design development. I was having dinner many years ago with a man named Uwe Wascher who was a VP for GE Plastics. After a few drinks, he recalled his role in the development of Xenoy as the first ever-bumper material for a European car. Wascher, who is German and was based in Europe, said he sold the OEM on polycarbonate before testing had been fully completed. PC (developed by GE’S Dan Fox about the same time Bayer also discovered the polymer) was used on some prototype models, and was damaged by gasoline spills because of its poor chemical resistance. Washer set up a major research skunk works in GE corporate office in Europe. The 24/7 push—because the model was close to production—led to development of a PC/PBT polyester alloy known as Xenoy. The rest is history.
Wascher left GE several years ago, and probably has PR people with him when he has dinner with reporters these days.
The 100-percent solar-powered Solar Impulse plane flies on a piloted, cross-country flight this summer over the US as a prelude to the longer, round-the-world flight by its successor aircraft planned for 2015.
GE Aviation expects to chop off about 25 percent of the total 3D printing time of metallic production components for its LEAP Turbofan engine, using in-process inspection. That's pretty amazing, considering how slow additive manufacturing (AM) build times usually are.
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 radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
