At NPE, injection molding machine (IMM) makers emphasized technologies that help molders make parts more sustainably and efficiently, with features that take advantage of the Internet of Things and Industry 4.0. Among IMM makers trying to help their users adopt more-sustainable manufacturing practices is Husky, which introduced its HyPET6e IMM preform press, designed to run high concentrations of recycled PET. Meanwhile, software makers, along with machine OEMs, were trying to help users unlock the possibilities of big data. ClariProd, a company that's spun off of a molding shop, is offering one way to get started — with a plug-and-play system to track downtime.
