Blow molding manufacturing process used to produce hollow plastic parts, such as bottles and containers. Different types of
blow molding machines are used depending on the specific requirements of the product being manufactured. Here are the main types of
blow molding machines:
1. Extrusion Blow Molding (EBM) Machines
Description: These machines extrude a tube of molten plastic (parison) which is then clamped into a mold and inflated to form the desired shape.
Applications: Commonly used for making bottles, containers, automotive parts, and industrial components.
Examples:
Kautex Maschinenbau
Bekum
Jomar
2. Injection Blow Molding (IBM) Machines
Description: This process involves injecting molten plastic into a preform mold to create a parison, which is then transferred to a blow mold where it is inflated.
Applications: Ideal for producing small, high-quality bottles and containers with precise dimensions.
Examples:
Nissei ASB Company
Jomar Corporation
Aoki Technical Laboratory
3. Stretch Blow Molding (SBM) Machines
These machines come in two main types:
a. Single Stage Injection Stretch Blow Molding (ISBM)
Description: Combines injection molding and blow molding in one machine. The preform is made and then immediately blown into its final shape.
Applications: Used for high-quality PET bottles for beverages, personal care products, and pharmaceuticals.
Examples:
Nissei ASB Company
Sidel SBO Series
b . Two Stage Reheat Stretch Blow Molding (RSBM)
– Description : Preforms produced separately using injection molding; reheated before being blown into final shape
– Applications : Widely used beverage industry producing large volumes PET bottles
– Examples :
* Sidel SBO Series
* Krones Contiform
Key Features Consider When Choosing Machine
1 . Clamping Force : Ensure adequate clamping force handling molds preventing defects during production
2 . Cavity Number : Choose appropriate number cavities based required production volume efficiency needs
3 . Cycle Time : Evaluate cycle time ensuring meets speed requirements maintaining quality consistency
Additional Equipment Auxiliary Systems
1 . Mold Temperature Controllers : Maintain consistent temperature ensuring optimal performance quality finished products
2 . Air Compressors Chillers : Provide necessary cooling air pressure supporting efficient operation blow molding processes
3 . Material Handling Systems : Efficiently transport raw materials finished products within production facility minimizing downtime maximizing productivity
By understanding these different types machines carefully evaluating specific requirements ensures choosing right equipment meeting diverse manufacturing needs!
