As every injection molder knows, the set of process parameters required to produce a good plastic part called “the injection window”.
Typically, these parameters include –
- The process pressures - melt, injection and back
- The process temperatures - melt and mold
- The process velocities throughout the injection phases
And all, within frame of times and length of movements.
The product design, mold design and mold producing, should all strive for the widest injection window to allow the producer to use as many variations and combination as possible of the above-mentioned parameters (wide injection window), thus allowing the process to fluctuate while still producing good parts.
A wide injection window will also shorten the setup time by making it easier to produce good part, and naturally – will reduce scrap and rejects.
Unfortunately, injection windows issues come to mind only when things go wrong and even then, understanding and visualizing the injection window boundaries is not simple… until Qualisense comes to help.
Qualisense’ unique analytics and graphic presentation makes the process results clearly visible and easy to grasp.
By analyzing and presenting the entire part’s physical parameters in one glance and in context of each parameter specification limits, Qualisense makes it visual and easy to understand as you can see in the screenshots below.
Once you see and understand your current production status, your operational decisions towards improving your process productivity become clear and almost obvious.
Combining the overall view with Qualisense’ inherent comparison feature makes
it is a very powerful tool to continually improve your Operational excellence. We will elaborate on the comparison features in a future post.
