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.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
Design engineers play a big role in selecting both suppliers and materials for their designs. Our most recent Design News Materials Survey says they continue to be highly involved, in some ways even more than the last time we asked to peek inside their cubicles.
Daihatsu is one of the first carmakers to customize car exteriors using 3D printing's mass customization capabilities. Effect Skins -- small exterior bumper and fender panels in different colors and textures -- can be ordered for its Copen convertible.
Several new products in this group of new adhesives, coatings, and sealants are formulated to protect sensitive electronic components, or to seal components of commercial and military aircraft. Others are designed to operate in tough, messy, dirty oil & gas operations, or for rotary applications and motors.
