At NPE 2006, Engel displayed an all-electric tiebarless machine that produced a two-cavity, two-component cover plate. This E-MOTION 110 Combi US molds parts from Liquid Silicone Rubber (LSR) and polybutylene terephthalate (PBT). After the in-line injection units inject the PBT, the second piggyback-mounted units inject the LSR. In addition to the multi-component advantages of new design possibilities, reduced cost and improved quality from the single-step process, the electric approach adds other benifits. "In general, if we compare an all-electric injection molding to hydraulic, the biggest advantage is efficiency, be it multi-component or single component is about 30 to 40 percent less," says Engel's Kragl. In addition, the all-electric machine reduces the noise level by as much as 10 to 15 dB compared to a hydraulic machine.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
