Polymer injection molding is a high-volume polymer repliction method where a viscous polymer is injected into a custom-made closed mold. After solidification of the polymer, the cavity is opened and the polymer part is ejected. | Polymer injection molding is a high-volume polymer repliction method where a viscous polymer is injected into a custom-made closed mold.

The injection molder at DTU Nanolab was an Engel Victory Tech 80/45 which is a hydraulic machine with single motor. The machine was also equipped with a robot which could pick up finished samples and place them on a conveyor belt. See the table below for key capabilities of this machine.

There are no standard injection molding processes because it varies significantly how users prefer to optimize their process and how they prioritize parameters such as polymer type, replication fidelity, dimensional accuracy, optical properties, residual stress and cycle time. However, browsing through the [http://labmanager.dtu.dk/function.php?module=Processlog&view=editlog&machid=278 Process Log] it's usually not a problem to find a program made for the polymer and tool at hand which can be used as a starting point. | There are no standard injection molding processes because it varies significantly how users prefer to optimize their process and how they prioritize parameters such as polymer type, replication fidelity, dimensional accuracy, optical properties, residual stress and cycle time.
