Airbags are standard equipment in automobiles today. They can save lives in emergencies, yet when no danger is present, they lie dormant beneath a cover made of plastic. These kinds of plastic components are usually injection molded. Plastic is melted, then injected into a mold for the corresponding piece and cooled until it is rigid again. Meanwhile, a new process has frequently been employed for producing the airbag covers. The process is called thermoplastic foam injection, or FIM.
