Engel (York, PA) will reprise a live demo molding interdental brushes that it has exhibited at other shows in the recent past, but if you missed it, it deserves to be on your must-see list. A cleanroom version of the all-electric e-motion 170/110-T will mold the product at NPE2018—including the grip surface and core—with up to 500 bristles formed in a single-component injection mold.
“As a rule, interdental brushes consist of three components—the grip surface, a wire mesh and the filaments—which are usually produced in independent processes,” explained Jon Kelm, Manager of Medical and Packaging Business Units for Engel North America. “By contrast, our solution does away with the entire work steps and reduces the logistical effort.”
The mold was built by Hack Formenbau, with Hekuma providing automation for the production cell, built in the modular Hekuflex design. Immediately after injection molding, the parts are inspected by a vision system and packed in retail bags, each one containing 16 parts. A bag leaves the production cell every four seconds.
