Injection Stretch Blow Mould (isbm) (two Stage)
INJECTION STRETCH BLOW MOULD (ISBM) (TWO STAGE)
In the two-stage process, the preforms are moulded in a dedicated injection moulding system which produces fully-cooled preforms. These preforms can then be stored, shipped, and even sold, before being blow moulded in a different machine. The blow molding machine unscrambles the preforms, reheats them with infrared radiation, and conditions them before blow molding.
Specifications:
- Flexibility.
- High Production with Efficiency.
- Cost saving.
- Zero material wastage.
- High transparency.

Two stage ISBM mould manufacturer
A Two Stage Blow Mould Manufacturer plays a critical role in producing high-performance PET bottles using the Injection Stretch Blow Moulding (ISBM) process. In this advanced system, the production of preforms and the final bottle blowing process are carried out in two separate stages, allowing greater flexibility, higher production capacity, and improved control over product quality.
A professional Two Stage ISBM Mould Manufacturer designs and engineers mould systems that are widely used in beverage, pharmaceutical, food, cosmetics, and chemical packaging industries. These moulds are built using high-grade tool steel, precision CNC machining, and advanced engineering techniques to ensure long-lasting durability and consistent output in high-volume production environments.
Two-stage ISBM systems are especially preferred by manufacturers who require large-scale production with optimized efficiency and superior bottle quality.
What is Two Stage Injection Stretch Blow Moulding (ISBM)?
Two Stage ISBM is a manufacturing process where PET preforms are first produced using an injection moulding machine, and later reheated and blown into bottles using a separate blow moulding machine.
This separation of processes offers greater flexibility in production, storage, and distribution of preforms.
A Two Stage ISBM Mould Exporter supplies moulds that are compatible with high-speed blow moulding machines, ensuring smooth operation and consistent bottle formation.
How Two Stage ISBM Process Works
The Two Stage ISBM process consists of two main steps:
Stage 1: Preform Injection Moulding
In this stage, PET material is injected into a mould cavity to create preforms. These preforms are cooled, stored, and transported as needed.
Stage 2: Reheating and Blow Moulding
The stored preforms are reheated to a controlled temperature and then stretched and blown into final bottle shapes using high-pressure air.
This process ensures better production planning and large-scale manufacturing efficiency.
Advantages of Two Stage Blow Mould System
A Two Stage Blow Mould Manufacturer focuses on delivering systems that offer multiple operational and commercial benefits:
High Production Flexibility
Preforms can be stored and used as per production demand, allowing flexible manufacturing schedules.
Large Scale Production Capability
