Micro injection molding is a highly specialized manufacturing process used to produce extremely small, high-precision thermoplastic components with micron-level tolerances and intricate features. It involves molding plastic parts that typically weigh less than 1 gram and have dimensions measured in millimeters or microns (1 micron = 0.001 mm). Micro molding can produce parts with tolerances as tight as ±0.003 mm (±0.0001 inches) and features like thin walls (0.1 mm), micro holes, and sharp corners.
