Injection molding

Nanotechnology can be used to make cheap plastic parts with functional surfaces.

The functional surface can be obtained with injection molding using a standard injection molding plastic. The nanostructures are transferred from the surface of the injection molding tool to the surface of the molded plastic parts. 

In the Nanoplast project, structural color pixels have been realized in a injection molded plastic parts. The plastic parts were injection molded using a steel insert mounted in a commercial injection molding tool. 

The steel insert has been fabricated using a unique method developed in a close collaboration between the partners of the Nanoplast project.

The same method is currently used to fabricate inserts for injection molding of curved plastic parts.
