RE: ICM Compression switch has huge impact on warpage. Why?
In all Injection Compression Molding (ICM) cases we have been doing we found that a slight change in Compression-switch has a huge impact on warpage. Why is this?
This means that before the compression switch, the amount of resin injected is calculated as: (Part + Compression) * VP switched volume (i.e., 70%).
Therefore, the difference in resin volume is an influencing factor that causes the variation in warpage. The change in resin quantity affects the pressure, which in turn influences warpage.
