WEBINAR: Wake-Up Call to the Benefits of Simulation for Warpage and Windage
The impressive response of manufacturing to the urgent medical product development and delivery challenges COVID-19 presented was due in part to the use of simulation software. This free webinar takes attendees through a real-world example that used mold flow simulation to identify Kentucky Windage as the cause of warpage issues on a much-needed medical device.
“Mold flow simulation is so good because of its ability to filter out what is causing warpage,” CAE Services Director of Engineering Tim Lankisch says. Warpage is not always about cooling. Consider new gate location, pressure improvement, L-shape warpage improvement and volumetric shrinkage improvement. The key is good material data!
Take, for example, the bracket-02 metering accumulator CAE Services worked on in a very short amount of time that involved perpendicularity issues and excessive sink (when going from a machined design to an injection mold design). CAE got engaged and got it done with Mold Flow simulation in 18 days!
The key was identifying the warpage issue. “So you’ve done everything you can and you still get a warped part … then what?” Lankisch asks. The next step was Kentucky Windage where you are “biasing steel in the opposite direction of the warpage.” The challenge is determining the windage factor, which is traditionally calculated by trial and error—a lot of back and forth between the molder and mold builder.
“Tuning loops are commonly 9-13 weeks, but with Moldflow windage analysis you can knock it down to as little as one week,” Lankisch says. It’s all about doing BEFORE instead of AFTER. CAE proved that rapid mold flow and rapid windage are possible!
