Injection molding of plaques A Milacron injection molding machine was used to prepare plaques for the measurements of physical properties and adhesion.
The barrel temperature of the injection molding machine was set from 180°C to 235°C (360°F to 455°F) and the injection velocity from 15 mm/sec to 65 mm/sec.
