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
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
Some in the US have welcomed 3D printing for boosting local economies and bringing some offshored manufacturing back onshore. Meanwhile, China is wielding its power of numbers, and its very different relationships between government, education, and industry, to kickstart a homegrown industry.
You can find out practically everything you need to know about engineering plastics as alternatives to other materials at the 2014 IAPD Plastics Expo. Admission is free for engineers, designers, specifiers, and OEMs, as well as students and faculty.
