Understanding Blow Molding Technology

What Is Blow Molding?

Blow molding is a plastic manufacturing process used to create hollow objects by inflating heated plastic inside a mold cavity. It is particularly suitable for producing containers that require uniform wall thickness and high structural integrity.

Basic Process Overview

1. Plastic resin is melted and formed into a tube (parison or preform).

2. The mold closes around the plastic.

3. Compressed air inflates the material to match the mold shape.

4. The plastic cools and solidifies.

5. The finished container is ejected.
