Booming demand for aircraft and power generation plants is fueling higher requirements for a specialized investment casting process that creates complex hollow internal shapes. Use of molded ceramic cores allows turbine engine blades and vanes to be cast to size with complex cooling passages, permitting engines to operate at higher temperatures with greater efficiency. GE Aviation has a record number of engines on order through 2012, its third record year in a row. The cores are also used for turbines in natural gas power generation plants.
One of the beneficiaries is a company called Certech, which is the largest independent producer of ceramic cores for investment casting. Technology growth is in materials development. “We’re always looking for a better mousetrap to give a better yield to the customer,” says Michael Kasberg, vice president and general manager of Certech. “When they pour metal around our parts sometimes they want to pour hotter metal. As a result you need a ceramic that won’t melt when it sees a higher temperature. “
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
At the JEC Europe 2015 composites show in Paris last month, makers of composite materials, software, and process equipment showed off their latest innovations. This year's show saw some announcements related to automotive applications, but many of the improvements came in the world of aerospace.
The DuPont-sponsored Plastics Industry Trends survey shows engineers want improved performance in a broad range of plastics and better recycling technology. These concerns top even processing enhancements that improve productivity.
Plastics leader SABIC recently announced a global initiative to help its customers take advantage of additive manufacturing (AM) and also advance 3D printing (3DP) technologies in several application areas. The company's plans go way beyond materials, and also include design, processing, and part performance.
