In a new process, a metal insert is partially premolded and then overmolded using conventional technology with traditional plastics used for housings. In the premolding ptocess, conductive paths are affixed in place, and are also tightly sealed in one step. Application targets are sophisticated automotive mechatronic parts such as transmission and brake controls, sensors and plug-in connectors. A key new material is a nonreinforced copolyamide that overmolds the electrical conductive paths in electronic components, ensuring there is no contact with moisture or oil. According to a technical expert at BASF, the material’s developer, the polymer adheres very well to either metals or plastics. To compensate, other sealing methods, such a silicon adhesives or hot melts, were used. Some engineers even precoated metals to improve adhesion
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
