2. Understanding Blow Molding Machines
What is a Blow Molding Machine?
A blow molding machine is a specialized manufacturing equipment used to produce hollow plastic objects by inflating a heated plastic tube until it takes the shape of a mold. This process is widely used to create products like bottles, containers, tanks, and other plastic-based hollow structures.
How Blow Molding Works
The blow molding process begins with melting plastic and forming it into a hollow tube, known as a "parison" or "preform." The tube is then clamped inside a mold, where compressed air is introduced, causing the plastic to expand and take the mold's shape. Once cooled and solidified, the finished product is ejected.
Key Types of Blow Molding Machines
- Extrusion Blow Molding (EBM): Used for producing large, complex, and high-volume products such as containers and industrial tanks.
- Injection Blow Molding (IBM): Best suited for precision manufacturing of medical and pharmaceutical containers.
- Stretch Blow Molding (SBM): Commonly used in the production of PET bottles for beverages, personal care, and household products.
3. Market Size and Growth Trends
