More zones, greater control

At Amerimold 2012 (June 13-14; Novi, MI), DME Company (Booth 307) showcased a new, 16-Zone Hydraulic Valve Gate Sequencer, which is aimed at processors seeking greater precision in sophisticated molding applications.

The increase in of timer-based zones from four to 16 includes control over electronics to match the hydraulic zone instead of using physical timers per zone, giving more responsive control of more valve gates.

DME says the new sequencer greatly reduces electrical usage over the life of the unit, and the controllers can operate from a wide supply of operating voltages for easier relocation between plants and countries. The controller plug can be replaced with 240 VAC plugs for instantaneous operation.

The 16-Zone Valve Gate Sequencer also features a new PLC touchscreen to facilitate easier operation. Molders can save and load mold recipes, view a log that shows the last 200 changes, and utilize dual-time functions which permit each zone to have both a programmed delay time and an on-time. The sequencer also has a manual mode that can turn all outputs on and off.

DME Company is a mold technologies firm that produces hot runner systems, control system, mold bases and components, moldmaking and molding supplies and cold runners for elastomers.
