Extrusion Blow Molding VS Injection Blow Molding, what is difference?

At Maiwei, a leading blow molding machine factory, we specialize in providing advanced solutions for both Extrusion Blow Molding (EBM) and Injection Blow Molding (IBM) processes. Understanding the differences between these two methods is crucial for selecting the right technology for your manufacturing needs. This article explores the key distinctions between EBM and IBM, helping you make an informed decision for your production line.

Extrusion Blow Molding (EBM)

Process Overview:
Extrusion Blow Molding involves melting plastic and extruding it into a parison (a tube-like piece of plastic). The parison is then captured in a mold and blown with air to form the desired shape. This method is highly efficient for producing hollow parts and containers.


  1. Versatility: EBM is ideal for creating a wide variety of hollow shapes, including bottles, containers, and automotive components.
  2. Cost-Effective: The EBM process is generally less expensive than IBM, particularly for high-volume production runs.
  3. Material Efficiency: EBM allows for the use of a wide range of plastics, including polyethylene, polypropylene, and PVC.
  4. Large Part Production: EBM is well-suited for producing larger parts that would be challenging with IBM.


  • Household containers (detergent bottles, shampoo bottles)
  • Automotive parts (air ducts, fuel tanks)
  • Industrial containers (chemical containers, drums)

Injection Blow Molding (IBM)

Process Overview:
Injection Blow Molding begins with the injection molding of a preform, which is then transferred to a blow mold. The preform is heated and air is blown into it to create the final shape. IBM is known for producing highly precise and consistent products.


  1. Precision: IBM offers superior control over wall thickness, resulting in high-quality, consistent parts.
  2. Surface Finish: Parts produced using IBM typically have a better surface finish compared to those made with EBM.
  3. Material Optimization: IBM reduces material waste due to its precise molding process.
  4. Product Consistency: Ideal for applications requiring uniformity and accuracy, such as pharmaceutical and cosmetic containers.


  • Medical and pharmaceutical containers (vials, jars)
  • Cosmetic packaging (cream jars, lotion bottles)
  • Small to medium-sized bottles for beverages and other liquids
