Process by which components, such as terminals, pins, studs, and fasteners, may be molded into a part. Instrumented impact testing A mechanically or hydraulically driven dart is driven at a constant velocity through a plastic test specimen. The dart tip or driving mechanism has transducers and high-speed data-gathering computers to measure and analyze the energy required to break the specimen.

The injection of molten plastic into the surrounding area of metal stamping parts in order to combine the stamping parts into a single piece.

Insert molding cuts the cost of a traditional mold by making the core/cavity into a set of inserts that fit into standard prefabricated bases thereby negating the need to make the entire mold.
