1. Definition
An IBC Tank Blow Molding Machine Production Line is a complete automated system designed to manufacture large hollow plastic containers, especially IBC (Intermediate Bulk Container) inner tanks, by using the extrusion blow molding process.
The production line mainly processes HDPE (High-Density Polyethylene) and similar thermoplastic materials, producing containers with the following characteristics:
- One-piece hollow structure
- High mechanical strength
- Excellent chemical resistance
- Long service life
- Suitable for storage and transportation of liquids or powders
In practical applications, IBC inner tanks are usually combined with steel cage frames and pallets, forming standardized IBC containers widely used in global logistics.

6. Working Principle
- HDPE raw material is fed into the extruder
- The screw melts and homogenizes the material
- Melted plastic is extruded through the die head to form a parison
- The mold closes around the parison
- Compressed air inflates the parison to fit the mold cavity
- The product is cooled and solidified
- The mold opens and the product is released
- Flash and excess material are trimmed
- Finished products are inspected and stacked
