INJECTION MOLDING: Magnetic Clamps Gain Added Safety Features

System monitors magnetic flux at each pole on the platen.

At the Fakuma 2014 show in Germany last October, EAS Mold & Die Change Systems (U.S. office in Menomonee Falls, Wis.) showed off its new-generation magnetic mold-clamping system. It reportedly boasts the highest safety yet by monitoring the magnetic flux pole by pole across the platen, rather than sampling only one or two reference poles per platen.

In development are new controls that interact with the press. EAS is working with machine builders such as Engel and KraussMaffei to develop a mold database and controls that test the magnetic clamping force each time the mold is mounted in the press and signals the machine control to adjust the mold-opening force accordingly.

Also new from EAS is a now-standard modular line of mold-change carts for full automatic, horizontal mold loading.
