Spinning off from design work it did for an agricultural customer, the Heim Division of RBC Bearings (www.rbcbearings.com) will soon offer all customers the opportunity to get a custom, injection-molded, engineered thermoplastic self-lubricating race in standard rod ends. "Our injection molding method requires no drilled hole in the rod-end head," says Heim's Rick Williams. The result, he adds, is a high-strength self-lubricating rod end that can be tailored to specific applications.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
