A method for forming highly defined and detailed micro-channeled components (620, 640, 660) using injection molding of polymeric material (210, 220) is presented. Such micro-channel components (620, 640, 660) can be created by holding the temperature of the injection cavity and mold in excess of the glass transition temperature (Tg) of the polymeric material (210, 220) while the polymer is injected. The polymeric material (210, 220) can also be injected under pressure (P) to facilitate the forming of the highly defined micro-features. The newly created polymeric substrate (610) can then be ejected from the mold and used in micro-fluidic and other applications requiring precise and uniform micro-channeled structures. |
