NR8000 Tower
Nolden multifunctional concept
Our vision of process control
It has to be simple – easy to install and easy to use! Based on this
vision developed the multifunctional NOLDEN concept that combines in one
device all the control functions required in an injection mold, such as
also in the hot runner. This means less space around the injection molding machine, less
cabling and simplified data maintenance for all functions
devices. Another advantage – the device “moves with the tool” and can
can be used on any suitable injection molding machine, which means more flexibility
in production planning.
Cooling
Individual monitoring of all cooling channels
Effective tool cooling is critical
for detail quality. In order to achieve an economical cycle time, bridging all cooling channels is often not enough, here the parallel connection of all channels with the proven ORCA measuring manifold helps. All flow and temperature alarms are displayed and monitored directly in the NOLDEN control system.
Servo motor
Servo motor control
directly from the hot runner controller
Servomotors are rapidly conquering tool technology and replacing hydraulic or pneumatic cylinders – precisely, very quickly and maintenance-free. All common motors can be connected
directly to the NOLDEN hot runner controllers of the NR8000 series. Suitable for both linear and rotational applications, the visualization adapts automatically.
Cascade control
Sequential control of needle lifting actuators
For parts with a large area or smaller thicknesses
walls, hot runner nozzles often need to be controlled sequentially, this is not a problem with NOLDEN cascade control. Activation may be time or cochlear dependent; it is also possible to perform several needle movements in one injection cycle. Exchange of signals with the injection molding machine using the core extraction interface (EUROMAP) or using programmable inputs and outputs.
Internal pressure measurement
Hot runner controller direct injection pressure monitoring
Pressure monitoring waMeasuring the internal pressure directly in the cavitation space is the current state of the art – unfortunately, it is often very expensive and cumbersome to operate. In NOLDEN, pressure sensors are connected directly to the control unit, visualization and monitoring of injection curves is done simply on the touch screen. Both direct sensors and underlay sensors can be controlled independently of the manufacturer. Integrated patented evaluation for NOLDEN direct injection control systems in the hot runner controller
