Optimum holding pressure time in injection moulding

Faster to series production with iQ hold control setpoint assistant

The sealing point, also known as the holding pressure time in injection moulding, is typically adjusted individually after mould setup. Several components need to be test-moulded and analysed in the quality laboratory. The iQ hold control software automatically optimises the holding pressure. The result: No manual effort, savings in time and raw material, optimised cycle time.

Advantages of automatic holding pressure adjustment in injection moulding
Faster start of series manufacture

Manual determination of the holding pressure time during injection moulding through sealing point determination is time-consuming. Parts must be removed from the production process. Equipment (a scale) is needed to check the weight of the moulded part. iQ hold control, on the other hand, determines the holding pressure time automatically and within defined limits.

Less scrap due to automatic parameter setting

Finding an optimum holding pressure time in injection moulding requires a lot of experience and is time-consuming. Process engineers often only set the most necessary parameters. Incorrect settings lead to unnecessary scrap. iQ hold control determines the holding pressure time objectively. The software supports less experienced process technicians while also helping experienced technicians save time.

Easy operation via the machine control system

iQ hold control is started via a dedicated button on the machine control screen. At the push of a button, the correct holding pressure time for the injection moulding process is determined - fully automatically. After a few cycles, the software finds the optimum setting and suggests it to the operator.

Do you want to automatically optimise the holding pressure time in injection moulding?

Our experts will be happy to answer any questions about iQ hold control.

Enhancing productivity through time savings

During the hectic production process, one often does not have the time to optimize all injection moulding process settings. Without iQ hold control, it would have taken me at least 3 hours to accurately determine the holding pressure time. I could now use this time for other tasks.
