Growing miniature materials demand for several applications in end-use industries such as electronics, telecom, automotive and medical is anticipated to drive the global polymer microinjection molding market growth over the next five year, as per hexaresearch.com. Polymer microinjection molding process is used to manufacture micro sized tools and parts through a machine comprising fine resolution, injection pressure, and high speed specific molds as per requirements. Some primary polymers used for the process include polymethyl methacrylate (PMMA), polyether ether ketone (PEEK), polyoxymethylene, polyethylene, polylactic acid and liquid crystal polymer.Increasing demand for micro materials in electronic and medical industry is expected to bolster the global market over the forecast period. Shifting focus towards substituting polymers comprising phthalate with thermoplastics is anticipated surge the demand for microinjection molding in medical industry. Microinjection molding is used to manufacture parts and tools which require accurate geometries and high precision features such as micro filters, bearing caps and ear implants. Other important product applications include micro gear plate, wheel and operating pin in automobile industry. Microinjection molding is more advantageous than micromachining. It takes less molding time with high precision and uses low cost feedstock such as PEEK, whereas micromachining uses stainless steel which results in high manufacturing cost.
