Injection blow molding is a process that combines injection molding and blow molding. A plastic preform is first injection molded, then transferred to a blow mold where it is inflated to its final shape. This process provides superior dimensional accuracy and surface finish, making it ideal for medical, pharmaceutical, and laboratory applications.
Injection blow molding offers tighter dimensional tolerances, more consistent wall thickness, better surface finish, and no flash or pinch-off lines, making it well-suited for precision medical and pharmaceutical components.
