Injection stretch blow molding (ISBM) machines

ISBM machines combine injection molding of a preform and its subsequent biaxial stretching and blowing into a final container. This biaxial orientation enhances molecular alignment, delivering superior mechanical strength, gas barrier performance, and optical clarity—critical for carbonated beverage packaging.

Modern ISBM systems from Jingye Machinery (WISB series) and TONVA (EFA series) feature servo-hybrid drives, CNC control, and preform temperature monitoring. They support both one-stage and two-stage processes and handle a wide range of polymers: PET, PETG, polycarbonate, and TRITAN—enabling production of bottles with complex neck finishes, lightweight walls, and custom aesthetics.

KNAVI GROUP supplies ISBM machines directly from manufacturers. All units undergo pre-commissioning, come with full English documentation, and include up to 2 years of warranty. Turnkey solutions—from line design to on-site training—are available.

Direct factory supply ensures fast delivery worldwide. Operator training and on-site commissioning are included.
