A pretty impressive example of micro injection molding is this “microwell array,”
which has millions of tiny wells measuring 3 microns in diam. and 3 microns deep,
with a pitch of 6.5 microns. These features appear on a standard microscope slide and are used in genomics, life-science, and biomedical assays that utilize microspheres or beads. Until now, the industry relied primarily on etched silicon or glass microwells. The part is molded by microPEP, div. of Precision Engineered Products, LLC in Attleboro, Mass. It selected Topas cyclic olefin copolymer (COC) from Topas Advanced Polymers, Inc., Florence, Ky., based on its excellent flow and surface replication, as well as high purity, biocompatibility, chemical resistance, low autofluorescence, and extra-high transparency in the near-UV range used in many tests.
