How to use Moldflow for Powder Injection Molding (PMI)!
One of my college roommates was teasing me about my last post. That made me think of another topic: Powder Injection Molding (PIM)!
This roommate (let’s call him T-BONE for anonymity) asked me about using Moldflow for PIM a few years ago. I told him sure, send over the model and process settings and I would run it through Moldflow Insight.
What I didn’t tell T-BONE was that I had never used the Powder Metal code within Moldflow. All good – fake it until you make it. What is the worst that could happen, I make a mistake? I have made so many mistakes in Moldflow, I stopped counting years ago.
I ran the model through Moldflow Insight and made a sweet report. While sharing with results with T-BONE, I told him that I thought his pack time was too long and the gate froze off at 8 seconds. T-BONE dropped the phone, ran to the press, came back, and said “You are right, pack time is actually 8 seconds”. We reviewed some additional plots around Volumetric Shrinkage, Shear Stress, and Powder Volume Concentration as well.
