Mold Temperature Control in Injection Molding

The iQ flow control software continuously adjusts the speed of the pumps in the temperature control units during production. Customer calculations show that this can reduce the energy consumption of the temperature control process by 85%. This results in CO₂ savings of approx. 160 t per year.

iQ flow control monitors the temperature difference in each distribution circuit of the e-flomo plus. The software calculates the cooling water requirement and passes this information on to the temperature control unit. The temperature control unit provides the appropriate amount of water and automatically adjusts to changing parameters.

You can easily operate iQ flow control as well as the hardware devices with the CC300 machine control. Important mold temperature control parameters in the injection molding process are available. The actual values of all temperature control circuits as well as those of the temperature control units, are displayed on the injection molding machine control. Changes and errors can’t be missed.

20% of rejects in the injection molding industry are caused by temperature control errors. iQ flow control decreases this number by increasing process consistency. If fluctuations occur, the machine is stopped before rejects are being produced.

Optimum temperature distribution in the cavity is crucial to produce, for example, high-gloss surfaces. As no shading occurs on the plastic parts and the gloss level remains uniform.

The ideal differential temperature control is repeatable during the next production. Mold temperature control in injection molding allows the production of good parts without repeating trials.

Intelligent mold temperature control in injection molding means that the pump does not have to operate constantly at full load. This reduces wear and the pump can be used for longer. Maintenance costs for temperature control units are cut down by up to 50%.

By bundling several temperature control circuits, less temperature control units are needed. This reduces the investment costs. Customer trials have shown that with ideal design and the recommended operating mode, the return on investment (ROI) can be two years.
