NOLDEN CONTROL SYSTEMSSince 1975 at your service for plastics processing

For more than 40 years, NOLDEN controllers are knownfor precise temperature control in the plastics processing industry. Originated from a small development companyfor high quality laboratory controllers, NOLDEN designsand produces today precise process control systems mainly for hotrunners and injection moulds.

Starting with temperature control in the hotrunner, more and more additional process control, diagnosis and moni-toring functions were added – that’s how NOLDEN brings you today the whole mould control in just one device. This simplifies a lot the operation and wiring and saves precious space around the injection press. In many cases – as for the integrated servo motion control or the new mould wiring box “MouldConnect” – NOLDEN was the trailblazer for new, innovative technology, shown by numerous patents and industrial property rights.

Our lastest innovation is a first of its kind in the world: NOLDEN evoControl© is a completely new control algo-rithm that finally eliminates the odds of traditional PID- based systems and revolutionizes temperature control! Get inspired by our new development on the following pages.

As a development and production company, we want to be at your service from the very beginning. This starts with profound information on specialized fairs and indi-vidual support to find the best suitable control system, of course with thorough testing cycle in your production environment. Also for future upgrades and function enhancements as well as service and repair – we would like to be your partner for the whole life time of your device.

NOLDEN evoControl®

A quantum leap in control technology

Control technology exists since the ancient world – a technical parameter as e.g. a water level, a temperature or a speed had to be controlled at a desired magnitude without human interference. For this purpose, man invented at all times automatical devices, beginning with simple lever arm – controlled water systems in ancient Egypt up to the – mostly electronical controllers of our time.

That’s how mother nature assures control: A network of

neurons exchanges informationas small stimuli and determines

control reactions in a veryprecise manner.

In the field of plastic processing, it’s very often temperature to be controlled precisely, as it is of great significance for the viscosity and thus process behaviour of molten plastic aggregates. Here, mostly so-called PID controllers are used, which combine Proportional, Integral and Differential behaviour to calculate the needed heating power adjustments.

The solution: An artificial neuronal network as a mathematical model,single neurons are compu-ting a small part of the con-trol algorithm very quickly, the total result is obtained by the networking action of all neurons.

Alas! this proven method features two big disadvantages,as everyone working in the plastic business knows well. 1. Overshoot: Before stabilizing at the desired setpoint, temperature over- and undershoots several times, they also say: “The controller gets tuned”.

2. Computing PID-values: To work precisely with a given hotrunner or mould, one must program the controller with the appropriate P-, I- and D-parameters. This should be done preferably without the interference of the operator, therefore, several so-called self-optimizing or “autotun-ing” methods exist. In many cases, this works properly and the temperature remains stable, in other cases, it doesn’t and the process is oscillating up and down. This is just what you don’t need in plastic transformation business!

That’s why numerous attempts were made to overcomethose drawbacks. We at NOLDEN Regelsysteme work since more than 40 years in this field, so, our engineers and research people looked for a completely new appro-ach and found it in nature.

In biology and neurochemistry, control operations are

performed by so-called neurons, combined to huge networks.

Every single neuron only performs a limited part of the total operation, the precision of the overall result is obtained by the number of neurons in the network. In addition, a fundamental advantage of neuronal networks is their ability to get “trained”, the propagation parame-ters of every neutron can adapt themselves to prevailing circumstances.

Artificial neuronal networks have been scientifically investigated in the recent years, they were mapped into mathematical models and used to describe complex, dynamic processes. NOLDEN was first to use those models to control temperature within the plastic pro-cessing industry and is proud to present with NOLDEN evoControl® the first process control system without any overshoot. evoControl® is applied for patent for NOLDEN.

This problem of conventional PID-control is well-known to everyone in the plastic processing world: Strong overshoot of actual temperature depending of the responsivity of the hotrunner or mould. One can attenuate it, but not completely suppres it.

It has to be easy - easy to install and easy to operate! Inspired by this vision, the NOLDEN multifunction concept was born, to combine all necessary control functions in the mould as well as in the hotrunner in just one box. This means less space needed around the injection moulding machine, less wiring and sim-pler data management for all functions. One more advantage – the box “moves on with the mould” and can be used on every suitable injection press, this gives you more flexibility in production planning.

For large parts or thin walls, hotrunner valve gates have often to be controlled sequentially, no problem with the integrated NOLDEN valve gate control system. Operation can be either time based or based on the position of the injection press screw, also, you can program several needle movements per injection cycle. Data exchange with the press can be done via the core puller interface (EUROMAP) or with programmable in-/ and outputs.

VALVE GATE CONTROLSequential control of valve gates

Effective mould cooling is key for good quality of the parts. To obtain economical cycle times, a simple bridging of all cooling ducts is often not sufficient, here, a good solution is the parallel flow of all ducts with the proven ORCA-cooling water distributor. Visualization and automatic alarms for all flow rates and temperatures are done directly on the NOLDEN touchscreen system.

Measuring the cavity mould pressure is now state of the art - Alas! quite expensive and often not easy to operate.With NOLDEN, just connect the pressure sensors directly to the hotrunner controller, visualization and monitoring of the pressure curves are then done on the touchscreen of the controller. Direct action sensors (in the cavity) as well as indirect action sensors (under the ejector pin) can be used, no matter from which manufacturer. Integrated monitoring system patented for NOLDEN Regelsysteme.

Perfectly matching with NOLDEN touchscreen controllers, MouldConnect simplifies drastically the wiring and connection of your mould. Just wire all temperature sensors, pressure transducers and other low voltage lines such as core pullers or proximity switches into the new MouldConnect box. From there, only 1 cable is needed to the control system.

One plus on top: As you connect the cable to the controller, the mould is auto-matically identified and mould data are loaded, you simply can’t do it easier!

Easy, user friendly operation is of great significance ininjection moulding – so many systems and increasingcomplexity are a challenge for most operators.

That’s why simple, intuitive operation was on top of the list when we developed the new NOLDEN STS – Smart Touch System. All functions as hotrunner heating, mould cavity pressure measurement or servo motion control are operated in a similar manner – and all mould data are stored in one common recipe memory.

All touchscreen controllers NR 7000 and NR 8000 are prepared for evoControl©, existing systems can be upgraded.

In many cases, just temperature control is sufficientand complex additional functions such as servo control or pressure measurement are not needed. Here, our new compact touchcontroller NR 8000 is the ideal solution: The same intuitive, user-friendly NOLDEN Smart Touch System with all features of the NR 7000 in a compact desktop casing for hotrunners from 8 up to 32 zones. Nevertheless, also for those controllers conventional valvegate control as well as cooling monitoring are available as an option.

The great success of our touch controller series NR8000 shows: This device is meeting the expectations of plastic processing professionals. That’s why we created a “Mini” version for 4, 6 or 8 zones. Operation and data managementare identical for all units up to 120 zones, so, transitioning between the systems is very easy. Sorry, no space left in this very compact casing for additional control functions, just the cooling water monitoring is avalaible as an option. And of course, always on board is evoControl©.

MOULD CONNECTION BOXES The hands-on solution for trouble-free wiring

Every professional knows the main problem in mould wiring: Lack of space! Many wires must be accom-modated in the small space of a connector housing. Perhaps, even a wiring change must be performed later on – this is where the proven NOLDEN mould connection boxes come in as a very practical solution.

for electrical mould heating – manufacturer independant

Often, time is short, an unplanned repair must by doneand spare parts are missing. Good to know that NOLDENhas a broad assortment of thermocouples, heating

elements and connectors available ex stock. Compatibleto most industries standards, independent from the brand of the injection press and at low prices.
