Engel to launch iQ flow control at NPE2018

Engel has expanded its range of intelligent peripherals, with its iQ flow control, consolidating its systems expertise. The temperature control solution improves the stability of injection moulding processes, reduces rejects and boosts energy efficiency. At the launch in North America, the Austria-based injection moulding machine manufacturer and system solutions provider will be demonstrating the new opportunities live at NPE2018, from May 7th to 11th in Orlando, Florida.

Joachim Kragl, Director of Advanced Moulding Systems and Processing in Pennsylvania, said: “Most rejects in injection moulding are the result of temperature control errors. This explains why the processors' focus is increasingly shifting to mould temperature control.”

With flomo, Engel laid the groundwork for more transparency and consistency in the temperature control process as one of the pioneers in this field back at K 2010. Engel flomo, an electronic temperature control water manifold system, replaces the maintenance-intensive cooling water distributors and even the basic version can individually monitor and document all cooling and temperature control circuits. The next generation e-flomo is further able to actively control either the flow rates or the temperature difference (?T) in all individual circuits. The advantage of ?T control is the automatic setting of the individually required flow rate for each temperature control circuit.


The CC300 control unit on the ENGEL injection moulding machines displays all temperature control components in a clear-cut way on a single screen, with the individual temperature control circuits of the mould in the centre.

iQ flow control software networks the temperature control units and the injection moulding machine to create a single unit and, based on the measured values determined by e-flomo, controls the pump speed in the temperature control units on demand. While e-flomo increases the process stability which consequently reduces the risk of rejects, automatic speed adjustment ensures that temperature control requires substantially less energy.

Since the pump operates on-demand rather than at maximum output all the time, stress on moving parts is reduced and temperature control units have a longer service life, which makes it possible to extend the maintenance cycles.

As an integrated solution, the entire temperature control process can be set up, monitored and centrally logged at the CC300 machine control display while the ideal operating point for the particular temperature control unit is determined and set automatically. This allows injection moulding shops to fully leverage their injection moulding machines' potential without the system operators needing special training.

To integrate the temperature control units with the CC300 control unit on the injection moulding machine, Engel collaborated with temperature control unit manufacturer HB-Therm (St. Gallen, Switzerland), to develop the temperature control unit series known as e-temp.

The extremely compact devices are networked with the injection moulding machine via OPC UA (Open Platform Communication Unified Architecture). With its service-oriented, platform independent and freely scalable structure, this communications model offers great flexibility.

A high degree of data security is guaranteed by the technical safety features that are an integral part of the architecture.

OPC UA is becoming increasingly popular in the plastics industry for networking injection moulding machines, peripherals, sensors and applications and is an important component of the inject 4.0 platform by Engel.
