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.
Sciaky, provider of electron-beam additive manufacturing (EBAM) services, will start selling these machines commercially in September. The company has used its EBAM 3D printing technology for making very large, high-value, metal prototypes and production parts for aerospace and defense OEMs.
At this year’s Google I/O, the spotlight was pointed on gender inequality in the high-tech industry. Google has established a new initiative that it hopes will even out the playing field, Made w/Code. Part of this initiative will fund free online courses in basic coding.
