Effect of Functional Nano Channel Structures Different Widths on Injection Molding and Compression Molding Replication Capabilities

摘要

The present study investigates the capabilities of the two employed processes, injection molding (IM) and injection compression molding (ICM) on replicating different channel cross sections. Statistical design of experiment was adopted to optimize replication quality of produced polymer parts with the two different molding technologies. Focus of the experimental work was the assessment of the IM and ICM processes capabilities to replicate different channels widths (240 nm, 440 nm and 1040 nm) at different positions from the gate based on the deviations of their dimensions from the corresponding geometries measured in the nickel master. Results presented as main effect plot of channel depth deviation from ideal nickel master and polymer replicated features are reported.
