The evolution of manufacturing processes for micro‐featured epoxy resin mold

Micro‐injection molding or micro‐hot embossing is a highly effective process for fabricating micro‐devices with microfeatures in polymer. Based on the strong demand on the precision components in the precision machinery industrial, two major concerns are the time and expense required for producing a precision mold for microfabrication. To enhance the competitiveness in the market of micorcomponents, this study presents six approaches for manufacturing precision epoxy resin molds with microfeatures. Evolutions manufacturing processes are described experimentally. Characteristics and applications of micro‐featured epoxy resin mold are introduced in detail.
