Single-Stage and Two-Stage Bottle Production Systems

PET container manufacturing relies on two distinct process methodologies: single-stage (1-step) and two-stage (2-step) bottle production systems.

The core differences between these processes include:

1-Step Process (Single-Stage): Integrates preform injection molding with stretch-blow moulding inside a single PET bottle making machine. Finished containers are produced directly from plastic resin in one continuous operation.
2-Step Process (Two-Stage): Separates container manufacturing into two distinct phases. Preforms are first produced on an injection molding system, then reheated and processed on a standalone PET bottle blowing machine.
