Abstract
A stretch blow molding method may include fabricating a preform (e.g., by molding, optionally while a core pin rotates within a mold cavity), heating the preform to a softening temperature, stretching and thereby elongating at least a portion of the heated preform, blowing the elongated preform with pressurized fluid within a mold cavity, and cooling the resulting pipette. A system for fabricating a stretch blow molded pipette includes a first mold defining a mold cavity for producing a preform. A stretch rod drive unit is configured to move a stretch rod within an interior of the preform to form an elongated preform, and a second mold defines blow molding cavity and a molding surface to contain expansion of the elongated perform when subjected to blowing by supplying pressurized fluid to an interior thereof.
