Micro molding – also known as micro injection molding – is a high-precision injection molding process that can create parts that are extremely small and precise. To create a micro mold, a highly detailed tool is used to shape a final part. Once the micro mold is created, it is placed into a micro molding machine where it is filled with molten plastic. The plastic is then injected into the micro mold under high pressure, and cooled to form the final part.
