Optimum holding pressure time in injection molding

Faster to series production with iQ hold control setpoint assistant

The sealing point, also known as the holding pressure time in injection molding, is typically adjusted individually after mold setup. Several components need to be test-molded and analyzed in the quality laboratory. The iQ hold control software automatically optimizes the holding pressure . The result: No manual effort, savings in time and raw material, optimized cycle time.

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

Manual determination of the holding pressure time during injection molding through sealing point determination is time-consuming. Parts must be removed from the production process l Equipment(a scale) is needed to check the weight of the molded 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 molding 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 injection molding machine control screen. At the push of a button, the correct holding pressure time for the injection molding process is determined - fully automatically. After a few cycles, the software finds the optimum settings and suggests it to the operator.

Do you want to automatically optimize the holding pressure time in injection molding?

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 molding process settings..Without iQ hold control, it would have taken me at least 3 hours to accurately determine the holding pressure time. I can now use this time for other tasks.
