Extrusion Blow Moulding Machine Technology
Introduction
Extrusion Blow Moulding (EBM) is a popular process for manufacturing hollow plastic parts. It involves extruding a continuous tube of molten plastic and then blowing it into a mould. This technology is widely used for creating containers, bottles, and other hollow shapes with high precision and efficiency.
How It Works
- Material Extrusion: Plastic pellets are fed into an extruder, melting and forming into a continuous parison (a hollow tube of molten plastic).
- Blowing: The parison is transferred to a mould cavity, where it is inflated with compressed air to conform to the mould’s shape.
- Cooling: The blown plastic cools and solidifies inside the mould.
- Ejection: The finished product is removed from the mould.
Key Components
- Extruder: Melts and forms the plastic into a parison.
- Mold: Shapes the parison into the final product.
- Blow Pin: Injects air to expand the parison inside the mold.
- Control System: Manages the extrusion, blowing, and cooling processes.
Advantages
- Versatility: Can produce various shapes and sizes, including complex geometries.
- Efficiency: High-speed production with minimal material waste.
- Consistency: Uniform wall thickness and quality in finished products.
- Cost-Effectiveness: Lower tool and material costs compared to other molding processes.
Applications
- Packaging: Bottles, jars, and containers for food, beverages, and chemicals.
- Automotive: Air ducts, reservoirs, and other hollow components.
- Consumer Goods: Household items like toys and other plastic products.
- Industrial: Tanks, bins, and enclosures.
Recent Innovations

Injection Stretch Blow Moulding Machine Technology
Introduction
Injection Stretch Blow Moulding (ISBM) is an advanced manufacturing process used to produce high-quality, lightweight, and strong plastic containers, particularly bottles. The technology combines injection molding and stretch blow molding to create products with superior strength and clarity.
How It Works
- Injection Molding: A preform (a small, test-tube-like piece) is created by injecting molten plastic into a mold. This preform has a thick wall and is designed for subsequent stretching and blowing.
- Stretching: The preform is heated and then mechanically stretched in the axial direction, which aligns the molecular structure of the plastic.
- Blowing: The stretched preform is placed into a blow mold where it is inflated with compressed air. The air pressure forces the plastic to conform to the mold’s shape, producing the final product.
- Cooling: The molded container is cooled and solidified inside the blow mold.
- Ejection: The finished product is ejected from the mold.
Key Components
- Injection Unit: Forms the preform by injecting molten plastic into the mold.
- Stretching Mechanism: Mechanically stretches the preform in the axial direction.
- Blow Molding Unit: Inflates the preform to create the final shape.
- Mold: Defines the shape and dimensions of the final product.
- Control System: Manages the injection, stretching, blowing, and cooling processes.
Advantages
- Enhanced Strength: The stretching process aligns the plastic molecules, resulting in stronger and more impact-resistant containers.
- Improved Clarity: The technology produces containers with excellent optical clarity and surface finish.
- Lightweight Design: Allows for the production of lightweight containers without compromising strength.
- Versatility: Suitable for a wide range of container shapes and sizes, including complex geometries.
Applications
- Beverages: Bottles for water, soft drinks, and juices.
- Food Packaging: Jars and containers for food products.
- Personal Care: Bottles for cosmetics, lotions, and shampoos.
- Pharmaceuticals: Containers for medical and pharmaceutical products.
