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.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
