When does a plastic injection molding tool have to be maintained? Optimizer4D paves the way for maintenance at the right time – evaluating the actual condition of the machine, instead of trusting in interval based service.
The QASS-system delivers an image of the injection process via HFIM (High-Frequency-Impulse-Measurement). This image varies according to the tools degree of wear. A worn out tool generates a very different image than a new one.
This test is non-destructive and takes place in real-time. Simultaneously, the system runs a process monitoring and in many cases detects sluggish bolts and worn out ejectors.
With the QASS Optimizer4D it is also possible to do subsequent quality control. A few examples are movable plastic parts for speakers, ashtrays, navigation systems or similar components. The measuring system sorts out faulty components by detecting abnormal sound emissions.
Check for wear
HFIM images below: This is a plastic injection molding process. The area marked green shows the injection phase. The tool used in the process on the left has shortly been maintained, the image on the right shows the same tool after 5000 shots. The high amplitudes indicate that the air is compressed and material and tool might be damaged.
