Extrusion Blow Molding (EBM) vs Injection Blow Molding (IBM)

Process Types

EBM: continuous parison extrusion. Best for large containers (200ml-200L). Handles on bottles possible. Multi-layer for barrier properties. IBM: injection molded preform then blow. High neck precision. For smaller containers (5ml-5L). Two-stage process for PET bottles (reheat blow) is ISO standard for beverage bottles. EBM tooling $8000-30000 per cavity. IBM $15000-50000.
