Orycon’s T-700 sequential valve gate controller is designed for molding visually and structurally perfect parts. It comes in a mobile housing, has a touchscreen with high-resolution graphics, and is available in standard models of 12 and 24 control zones.
Because each zone can operate as many as eight times per cycle (for a total of 96 operations per cycle when using a 12-zone unit and 192 operations per cycle using a 24-zone unit), control of the melt flow pattern in the cavity can be improved by a factor of four over the average unit, the company says. This allows the elimination of flow lines, cold welds and other defects.
All units can operate based on both time and screw position. Accuracy is 0.01 sec. when operating based on time and 0.01 percent of screw travel when operating in position mode. Trip points for opening and closing the valve gates can be entered by sliding markers across the screen or by entering the desired timing or position using a pop-up keypad.
The controller’s touchscreen interface makes all the gate open and close operations visible at a glance. The radar-like sweep bar allows the operator to see in real time which gates are being operated at any particular point.
