Injection Blow and Extrusion Blow are both plastic manufacturing processes used to produce bottles and containers. Injection Blow involves an initial injection molding step to create a preform, which is then blown into the final shape. Extrusion Blow directly extrudes a tube that is then blown into a mold. While both roles require similar certifications and work environments, Injection Blow specialists focus more on precision molding, whereas Extrusion Blow workers handle larger-scale bottle production.
