Moldflow Analysis

Optimal process settings are critical to influencing the cost, quality, and productivity of plastic injection molding.
Process optimization is done using the following methods:

1. Injection speeds are usually determined by performing viscosity curves.
2. Process windows are performed varying the melt temperatures and holding pressures.
3. Pressure drop studies are done to check if the machine has enough pressure to move the screw at the set rate.
4. Gate seal or gate freeze studies are done to optimize the holding time.
5. A cooling time study is done to optimize the cooling time.
