Melt Design, Inc. (MDi) will feature its Dual Stage Filter Device at NPE, in addition to its high performance hot runner systems and variety of assorted components.

The device is mounted between the extruder barrel and the molding machine nozzle. Its unique design allows for two separate melt pathways: one path during injection, where the melt is filtered in two stages and homogenized through a series of decreasing-in-size grooves and openings; and via a separate path during decompression.

Decompression of hot runner molds occurs with virtually “zero” pressure drop, allowing for a faster and easier decompression cycle. In addition, during decompression, filtered debris will be bypassed and will remain trapped and undisturbed, as the melt follows a separate pathway. There are no springs or components to “stick” or clog up and the filter can routinely be cleaned up, if needed, by simply removing the adapter and purging.
