There's more going on than never-ending miles of corn fields in Nebraska — some innovative injection molding is going on, at HTI Plastics in Lincoln, Neb.
Yes, this month, Best Practices takes you to the Cornhusker State.
KraussMaffei Group selected HTI as a U.S. beta test site for its new all-electric injection press, the PX. HTI will act as a host site for the machine for a year and then have the option to purchase it.
It makes sense that HTI got one of the first PX presses. The molder is a KraussMaffei house, running 24 KM injection presses ranging up to 1,800 tons of clamping force.
And HTI began buying all-electric injection molding presses back in 2010, transitioning from hydraulic presses, even though Nebraska has some of the lowest energy prices in the nation. Of course, a manufacturing operation can always benefit from lower energy prices. But HTI officials say the all-electrics increase speed and efficiency, and give tight, highly repeatable molding as well.
KraussMaffei premiered the PX at the K 2016 show in Germany in late 2016, billing the press as a modular, "made-to-measure" press that allows customers to mix and match clamping and injection units, so a customer can tailor the machine to its specific molding needs.
Features of the PX include larger platens to accommodate a wider range of mold sizes, faster injection speeds and more ejector force.
