Precision injection molding is an important technology for improving productivity and lowering costs in fields such as electronics, photonics, and medical plastics by allowing the substitution of molded plastics for more expensive metal and ceramic parts. The work in this phase of the program examines correlations between morphology and precision of injection molded liquid crystal polymers. The materials were poly(benzoate naphthoate) polymers with several different filler packages including glass fibers and minerals. These materials show a distinct skin/core morphology in which the relative amounts of skin and core vary with process parameters. The precision of the parts is affected by this ratio of skin to core.
