Intra-mold sterilization of plastic-embedded needle

Methods for intra-mold sterilization of a plastic-embedded metal component of a product, such as a medical lancet having a metal needle embedded within a plastic lancet body. For example, a lancet needle is retained within a mold, plastic is injected to encapsulate the needle, and a specified minimum temperature is maintained for a specified minimum cycle time. In example forms, the specified minimum mold temperature is at least about 370 degrees Fahrenheit and the specified minimum cycle time is at least about 10 seconds.
